Gardening Resolutions

Leave a comment

By Marjorie Vendrig, Master Gardener in Training

We all start January with a list of hopes and plans for the coming year; some of us making resolutions for better nutrition and exercise, or improved habits for work and family. Resolutions are distinct from plans and projects and, when put into practice,  resolutions simply become new habits or routines. Gardeners have endless lists of projects and plans along with many resolutions as they prepare for a new gardening year. As with nutrition and exercise, it’s not easy to develop new habits and to maintain these throughout the year. One of the reasons I decided to become a Master Gardener was to acquire new knowledge and skills and update my habits and routines as a gardener.  I felt I needed a solid commitment to learn and educate, and after almost two years in, I am on the road to changing old habits and learning new ones.

When I moved from a large rural property to a small urban lot, paradoxically garden cleanup became much more complicated. I no longer had a large compost system, and there were bags and bags of leaves and garden waste that neighbours set on the curb every week in the autumn.  My Master Gardener course work helped me understand more about soil composition and why and how much of this garden waste could be used in my own garden.  My resolution was to keep all the leaves for mulch and soil improvement –  I didn’t want to put a single bag out on the curb yet I also wanted a fairly ‘tidy’ garden. After a few years trying different methods, I use my mulching lawnmower and have developed techniques and  habits that allow me to avoid the cumbersome and awkward garden waste bags.

Over the holidays, I’ve taken a casual survey asking for gardening resolutions for 2026. Family and friends –  some experienced gardeners, some new homeowners, along with gardeners interested mostly in vegetables, or in houseplants, in garden design or any other of the many aspects of gardening  – have sent me their thoughts on what they resolve to do as gardeners in 2026. The results aren’t surprising, one friend commented that when she looked over her list, she realized she had made the same resolutions for the last ten years! Making the same resolution year in, year out does not equate with failure, it simply means that it’s an important goal, one that’s important to maintain.

As you glance through this list, I’m sure you’ll nod your head in agreement, there might be a few that you will add to your own list, or even some where you can say it is no longer on a list because it  is without thinking. Generally, with the gardening season still far off, gardeners hope to avoid over consumption, have an interest in native plants and informed gardening.  The following resolutions are pretty straightforward; most are fairly manageable tasks.

  1. Plan garden projects in advance, keep notes of successes and failures.
  2. Prune for shape but also at the right time of year.
  3. Buy only what will get planted right away – and have the space prepared.
  4. Buy only the right plant for the right spot.
  5. Water and fertilize house plants on a regular basis.
  6. Source plant material from Canadian or local growers.
  7. Stay on top of deadheading, particularly to encourage new blooms.
  8. Learn more about growing and pruning clematis (or dahlias, or roses, or fruit trees, or anything else!!)
  9. Buy only what grows in my zone.
  10. More focus on native plants.
  11. More focus on plants to promote pollinators.
  12. Try a few new veggies in the garden.
  13. Fertilize, particularly with compost tea – and keep to a schedule for fertilizing.
  14. Learn more about pest control.
  15. Get better at composting.
  16. Stay on top of goutweed (or other invasives) eradication.

For me, these next two are the most interesting and in some ways, the most challenging:

  • Consider how AI (Artificial Intelligence) may be influencing gardening information or trends and respond accordingly.
  • Make gardening more fun, less work and obligation

Utilizing Tree Bark in Garden Design

Leave a comment

By Marilyn Homewood, Master Gardener

We are now on the uphill climb towards increasing daylength.  However, the bleakness of the season will be with us for some time yet. Increasing winter interest by incorporating trees and shrubs with unique bark is one way of dealing with the view.  There are some striking options available to us in this area.

Paperbark Maple (Acer griseum)

This is a small tree that once would not have wintered well here.  With the changing climate, it can now be grown in our area but I should caution that it still prefers a sheltered area and will not tolerate strong wind.  It has a mature height is about 25 feet with a spread of 15 -25 feet.  It’s trunk and limbs remind one of cinnamon sticks and the peeling bark is similar to that of a birch tree.  As a maple, it also has an impressive fall show when leaves turn shades of yellow, red and orange.  As for placement, it will grow in full sun to partial shade in well-drained soil.

Striped Maple (Acer pensylvanicum)

This is a native, understory tree in southern Ontario topping out at 30 feet. It prefers partial to full shade in cool, moist, slightly acidic soil.  The bark is distinct with green and white stripes.  One warning however, the tree is also known as “moosewood” as the deer and moose love to browse on the twigs.  Young trees should be netted to prevent damage from these critters.

Shagbark Hickory (Carya ovata)

This is a large tree growing 60-80 feet in height with a trunk diameter that can reach 1 -2.5 feet.  The bark separates into long plates as the tree ages which loosen from the trunk giving the tree a shaggy appearance.  This tree also produces sweet tasting nuts making the tree popular with squirrels and birds.  Hickory is best grown in moist soil and full sun but can tolerate some shade.  It prefers rich soil and is often found on hillside and in valleys where there is more moisture.  These are long lived trees (200 years).

River Birch (Betula nigra)

With a graceful form and attractive bark, river birch is a deciduous tree frequently used in ornamental plantings. It is a fast-growing shade trees, valued for the colorful exfoliatingbark. River birch is one of the most culturally adaptable and heat tolerant of the birches and a good substitute for white birches. It is also reputed to be more resistant to the birch borer that plagues the white birch.  Another appealing feature is the shimmering contrast when theleaves flutter in the wind, with lower leaf surfaces a different color than the upper surface. A medium to tall tree, growing 60-80 feet at maturity and about 40 wide. Trees typically live 50 -75 years. Although it naturally forms just a single trunk, it is frequently sold in multiple-trunked form with two to five trunks per tree.

Because it is a large tree, river birch makes a wonderful specimen planting for largerproperties. The canopy casts light dappled shade when young but provides medium shade when older. This species is a good choice for low spots and wet soils and should be planted in full sun.  It does well on clay as that type of soil retains moisture well.   It can tolerate dry summers once established.

 “Heritage” is a popular, vigorous cultivar often used as alternatives to white barked birches in landscapes due to its lighter bark color. It has heavily exfoliating bark, with layers of cinnamon, salmon and brown bark peeling back in big sheets to reveal creamy white inner bark. It looks best planted in multi-stemmed clumps.

This is just a smattering of what is available.  Why not spend a cold day searching the internet trees with interesting bark and see what pops up.

Creating a Garden Journal

1 Comment

by Emma Murphy, Master Gardener

Full confession – I have never kept a garden journal. I have been given one from time to time as a gift, but I’ve never got round to using them.

This winter I’m thinking about finally using one (because my memory isn’t getting any better with age!) and because I’d like to record my gardening experiments in our main perennial beds year over year, as well as my experiences with native plants in my small native plant nursery in Lakefield, Ontario.

Keeping a garden journal is a valuable practice for both novice and experienced gardeners. It helps you document your gardening journey, learn from your experiences, and plan for the future.

So Why Keep a Garden Journal?

To Track Progress – A journal can help document plant growth, flowering times, and harvest yields to see how your garden evolves over time.

Record Weather Conditions – Noting temperature, rainfall, and seasonal changes that affect your plants will help you understand their influence on growth.

For Inspiration – A journal is a great place to document ideas, designs, and observations that inspire your gardening, serving as a creative outlet.

For Improved Planning – Use your past experiences to inform future planting decisions, such as choosing the right plants for specific locations.

Pest and Disease Management – It’s great to keep a record of any pest issues or diseases, along with effective treatments, to reference in the future.

For Budgeting Purposes – Keeping track of expenses related to your gardening supplies and plants allows you to manage your gardening budget effectively.

Some Thoughts on Creating a Garden Journal

I found some great ideas on how to have a successful garden journal.

Choose the Right Format – Decide between a physical notebook, a binder, or a digital platform that suits your preferences. You might want to keep several different journals – one for your vegetable garden, one for seeds etc. It’s up to you.

Include Essential Information – Record planting dates, plant names, care instructions, and observations on growth and health. This allows you to compare information year to year.

Photos – Incorporate photos of your garden at various stages, including bloom times and harvests.

Be Descriptive – Use descriptive language to capture your feelings and thoughts about your garden’s progress and challenges. Think about how your garden makes you feel during different times of the seasons.

Create Seasonal Sections – Consider organizing your journal by seasons or gardening phases (preparation, planting, maintenance, and harvesting) for easier reference.

Set Goals and Then Reflect – Write down your gardening goals for each season and include reflections on what worked well and what didn’t.

Add Design Elements – Include sketches or diagrams of your garden layout. Use colour, stickers, or drawings to make it visually engaging.

Maintain Regular Updates – Set a schedule to update your journal regularly, such as weekly or monthly, to maintain consistency. This is one thing I will have to do in order to successfully use a journal.

Experimentation Section – Dedicate a space to document any new gardening techniques, experiments, or plant varieties you try.

Review and Revise – Regularly review your entries to spot trends and adjust for future growing seasons.

The Garden Continuum
Why a Journal is a Gardener’s Best Friend – explains the benefits of and tips for choosing the right format. This last link I found interesting as it explained the benefits of a digital vs hard copy journal.

“A digital journal can offer several advantages. First, it’s easily searchable so you can quickly find information on specific plants, techniques or projects. Second, you can easily add photos and other digital media to your entries, which can help you document your garden’s progress visually. Third, a digital journal can be accessed anywhere and from multiple devices so you can update it from your computer, tablet or phone. 

Writing by hand, however, can be a meditative and reflective experience, and it may help you to connect more deeply with your garden. Additionally, a handwritten journal can serve as a keepsake or heirloom that can be passed down through generations or to the future owners of your home.”

What I learned from my research on starting a garden journal (for this blog) is that you have to think about what YOU want to get out of your journal – inspiration, documentation, templates, a diary…whatever that is. So find a journal (or create your own journal) that meets your needs. If you find a great resource, please share it in the comments!

For now our garden in asleep for the winter, but it doesn’t mean we can’t start our journal and dream of springtime!

Cold Frames – A Mini Greenhouse in Your Garden

Leave a comment

by Brandi McNeely, Master Gardener in Training

I’m sipping my coffee on the deck, overlooking my vegetable garden. Everything shows signs of fall. The onions and garlic have been harvested. The green beans are finished for the season and are ready for the compost pile. The zucchini and summer squash are suffering from powdery mildew, and the tomatoes are carrying the last few fruits of the season. Although summer is ending, the fall gardening season is just beginning – and I have a secret weapon: a cold frame.

Why Cold Frames Work

Several leafy green vegetables can survive and even thrive in cooler temperatures. Kale, lettuce, Swiss chard, and spinach produce sugars that lower the freezing point of water in their cells, protecting them from damaging ice crystals. These crops tend to bolt in the heat of summer but thrive in the crisp days of fall. Still, even hardy plants will eventually succumb to our harsh Canadian winters.

That’s where a cold frame comes in – you can significantly extend your growing season with one. Imagine brushing snow off your cold frame in November to harvest fresh kale for a salad!

Cold frame basics (Source: “Large Cold Frame” by Ofer El-Hashahar, CC BY-SA 2.0)

What Is a Cold Frame?

A cold frame is a low, bottomless structure with a transparent lid that protects plants from wind and cold. The lid lets sunlight in, while the insulated base traps heat and creates a microclimate that can run several degrees warmer than the surrounding air. Ventilation is key – open the lid on sunny days to prevent overheating and ensure proper airflow.

Cold frames come in various styles depending on budget, materials, and space.

Types of Cold Frames

Traditional Cold Frame
Built from wood with an angled, hinged top – this could use glass, polycarbonate, or heavy plastic. They can be permanent or portable and built with reclaimed or new materials. An old window makes a perfect lid.

Straw Bale Cold Frame
 Stack straw bales to form a frame and cover with windows or plastic sheeting. Straw provides insulation and can be reused or composted in spring.

Hot Bed
 A sunken bed filled with compostable material such as horse manure, straw, or poultry bedding, covered with soil and topped with a cold frame. As the material decomposes, it generates heat, warming the soil below.

Tips for Success

  • Timing is everything: Sow spinach, kale, or lettuce in late August or early September to harvest well into late fall – or even December, depending on snow cover.
  • Ventilation matters: Even on sunny October days, closed frames can overheat. Keep lids open when needed.
  • Spring bonus: In March or April, use your cold frame to start early crops like lettuce or radishes, or to harden off seedlings before planting.

The Quiet Magic of Cold Frames

No matter which style you choose, a cold frame is a valuable addition to any garden. It helps you garden later into the season and gives you a head start in spring.

With one simple structure, you don’t have to say goodbye to your garden when frost arrives. Picture a crisp November morning—brushing snow from the lid and harvesting fresh spinach for breakfast. That’s the quiet magic a cold frame brings to your backyard.

Using Broken Branches as Plant Supports

2 Comments

By Marjorie Vendrig, Master Gardener in Training

Gardeners and municipal services in Peterborough and areas hit by the ice-storm are busy picking up the broken branches and limbs and using them for city compost and recycling programs.

Another use for some of this wood might be found in our own gardens, repurposing them for use as stakes and supports. The timing for the ice storm was perfect; the broken branches are young and supple and without leaves so they can be bent easily and shaped to suit needs. Small branches can be bent or twisted to create low supports for perennials or annuals that become leggy as the season progresses or to prop up flowers as the plants bloom. Heavier and longer branches can be used as poles for teepees in vegetable gardens for beans and peas or for climbers such as sweet peas and clematis.

British and European gardeners have historically avoided plastic and metal as garden supports, instead ‘pea sticks’ are the norm. Pea sticks are usually coppiced hazel branches, but any young pliable wood will work.  Birch, lilac, red dogwood, along with oak and maple twigs and branches are at the top of the list, willow is popular as well but it tends to root and sprout – an advantage or disadvantage depending on where and how it is used. In some cases, a branch with lots of twigs and small growth is the best choice as the plant will grow under and over the branches.  In in other instances the small twigs might appear messy and a visual distraction.  When selecting your sticks, it’s important to take into account your garden aesthetic – are you going for the scrambling abundance of a country garden, or the formal structure of a classic retreat? Sarah Raven, a well-known British gardener has taken things a step further and made an effort to use only native wood when creating plant supports for her vegetable gardens.

In the ice-storm clean up, I collected a few branches for use as supports. My sweet pea seedlings are ready to plant outside, they’ll be perfect growing up and around the broken branch of a very special cornus Kousa, a sad loss from the storm. The long stem on the bottom is cut off at a sharp angle to be pushed into the soft spring soil as deep as possible.  The spread of the small twigs and branches will be close to the ground within easy reach of the seedlings planted around the base where they will quickly grow up and through the twigs and branches. Clematis would also do well on this structure and it’s likely strong enough to withstand several seasons. The popular annual mandevilla vine is another good choice as a climber. All add vertical interest to garden design.

My scrambling cotoneaster became too leggy and suffered a lot this winter. It’s now had a hard prune and I am using the cut offs to create small branch cages around some perennials. Yarrow, nepeta, tradescantia, and phlox are good candidates for this simple approach. Four or more long branches, each about 3’ long and with a similar diameter were chosen.  The new spring growth from the cutoffs will soon turn brown so I snipped off the new

growth and twigs, then pushed the thick end of each branch into the soil about 6” from its base, repeating this at the other three corners, to create four points of a box around the plant. The upright ends of the branches are then bent into hoops towards the opposite corner and wound around one another to create a hoop. More support is provided at the front where the plant flops towards the sun. I’ve made the hoop about 2/3 the final height of the plant and should be able to increase the height a bit by untwisting the ends a bit, if necessary.  At the end of the season, I’ll leave the hoops in place if they are sturdy enough for another season or add them to the compost pile.

My technique is very much that of a beginner; I expect I’ll refine things with more practice. Even still, the natural wood hoops are more appealing than  a plastic pole with string around it. In formal gardens in the UK, I have seen cages of plant supports that are works of art in themselves. It all takes time and patience.

A Garden Visit – The Abkhazi Garden

1 Comment

By Marjorie Vendrig, Master Gardener in Training

Gardening is an incredibly versatile hobby, a hobby that can move around with you when you move house or travel near or afar. I’ve always made a point of visiting gardens whenever or wherever I travel. Out-of-town sporting events, family holidays, weddings, and even business travel have always included visits to public gardens, arboretums, or even garden centres. These visits are always aesthetically pleasing and relaxing. At the same time, they provide a chance to learn about the plant material along with some local history and culture.

On a recent trip to Vancouver Island I visited the Abkhazi Garden in Victoria.  It was early October, well past the glory days of summer and far too late to enjoy the rhododendrons – the highlight of the garden – at their prime.  That didn’t matter at all, the vistas were astounding, the property a real treasure where gardens wind their way over and around dramatic glaciated rock mounds. This is a site where the gardeners took full advantage of the topography and natural environment rather than change it or cover it up. It’s a one acre spot surrounded by urban Victoria yet each view from anywhere in the garden carries the eye to pleasing combinations of shape, colour, texture, and form. The main house and summer house were built in the late 1940’s reflecting the post-war Modernist sprit, resulting in a superb integration of house and garden.  The house and garden are carefully integrated, the blend of the natural and designed is seamless and sublime.

The story behind the garden is interesting as well. The property was originally purchased by Peggy Pemberton-Carter who, in 1946, had recently arrived in Victoria after having spent the war in prisoner-of-war camps in China. She soon married Nicolas Abkhazi, an exiled Georgian prince who had also been interned. The combination of their personal privilege and hardship found a creative outlet in their garden. In the beginning they acquired plant material from the finest nurseries, they were mentored by distinguished horticulturalists and over the next 40 years they experimented and refined their project.

The walk through the garden begins in the rhododendron woodland where the native Garry oaks provide the canopy for species and hybrid rhododendrons. Growing closer to the ground are the ferns and hostas with winter aconite, fawn lilies, camas and hardy cyclamen blooming in season. There’s also tigridia, primula, and galtonia, along with spring flowering bulbs.

A Spanish fir tree holds place of honour at the beginning of a meandering green path with an immense rock outcropping on one side and a profusion of heather and other mounding, textural interest on the other. The path was inspired by the Yangtze River and Peggy’s image of it near her childhood home. Side paths lead onto several naturally created rock ponds providing reflections of sky and other nearby plantings. At each turn or change in elevation the composition is unique and spellbinding.

Recent additions to the garden include a swathe of native camas and a collection of plants indigenous to the Caucasus region, these the result of a donation from the Georgian Ambassador.

The Land Conservancy of British Columbia (TLC) purchased the property in 2000 to save it from becoming a townhouse development. Part of the main room in the house has been refurbished as a Tea House. Community support is a large factor in the continued success and improvement of the garden: the entry fee is by donation and a large group of enthusiastic volunteers do much of the work around the garden.

Five Great Garden Practices for the New Year

Leave a comment

By Christine Freeburn, Master Gardener

With the new year days away, resolutions for 2025 might be on your mind. Here are a few easy garden practices you might want to include in those New Year’s Resolutions.

  1. Keep a record.

Have a file, record on your computer, write in a journal, put plant tags in a zip lock bag by year. Write on your tags the year & where you planted. It is important to know which hydrangea you planted, so if you need to research how to prune or how large it should get or if you want to purchase another, you will have that information. When you keep tags or record what annuals you plant, if it is something you want to repeat, you will have the exact variety when you go shopping the next spring. There are so many varieties of so many plants.

  • Keep things clean.

Disease is often spread through the tools we use. Have a pack of wet wipes in your tool box & clean tools after each use. Sharpen tools at the end of gardening season, so they are clean & ready to go in spring.  Although you should use leaves as compost, don’t leave diseased plants in your gardens. Place them in your green garbage. Keep houseplant soil free of fallen leaves as well.

  • Keep yourself healthy.

Stretch before going into the garden to do manual work. Limit yourself to an amount of time that is good for you and your body and stop when your time is up….your garden will be there when you come back. Take your water bottle with you. Wear gloves & hat to protect yourself. Don’t work in the blazing sun…. bad for you & your plants.

  • Do your research.

Right plant in the right spot will give you more chance of success. If you plant a water loving perennial in a dry sandy spot, the plant will suffer or fail. Planting a tall annual at the front of your bed will obscure the pretty ones behind it. Use the internet, but make sure you are using reputable sites where knowledgeable gardeners are sharing good information. Look for articles written by Master Gardeners or university professors or scientists. Look for websites that end with “edu.” You can also contact Peterborough Master Gardeners online (peterboroughmastergardeners.com) to ask questions or check out what events we will be at in 2025.

  • Enjoy your gardens.

Remember, you garden because you get enjoyment from your hard work. Wander through your garden, peaking at the new sprouts coming up or the gorgeous flowers opening. Breath deep. Enjoy the birds, insects and wildlife that visit. Research shows that gardening and being in nature help our minds, bodies & souls.

Happy New Year! From Peterborough Master Gardeners

Fall Colour in Your Garden

Leave a comment

by Cheryl Harrison, Master Gardener

Fall is a wonderful time of year!  The leaves are changing, often it is still warm, and gardening is winding down.  However, there can still be some beautiful colour and texture in your garden.

Fall tree and shrub leaf colour is caused by less sunlight and longer nights.  Chlorophyll production, which gives leaves their green colour, slows down and then stops. Eventually all the chlorophyll is destroyed. The carotenoids and anthocyanin that are present in the leaf then show their true colours….ranging from yellow to orange to red. 

Many garden plants are known for their fall colour.  We are all familiar with maple trees especially the sugar maple (Acer saccharum).  However, sugar maple trees grow to be large trees so what might be some other options?

Evergreens

Evergreens, as their name indicates, stay green year-round.  They can add rich colour in the fall and some winter interest in the garden.  Birds love evergreens because they provide shelter from predators and from bad weather as well as nesting sites and, in some cases, food.

Some evergreen examples, in my garden, include false cypress (Chamaecyparis).  This shrub grows slowly and needs little to no pruning.  Others to consider would be the various species of dwarf spruce (Picea) shrubs.  Perhaps a dwarf blue spruce for its small stature, slow growth and beautiful blue colour or a dwarf green spruce would work.  The dwarf shrubs take up less space than a full sized shrub so are great in a small, or any size, garden.

Dwarf Blue Spruce

Flowers for Fall

We still had annual zinnias blooming in mid-October.  This may be an old-fashioned flower but there are so many sizes, shapes and colours that it is well worthwhile.  A couple of perennials might include peonies…..not for their flowers (long gone, of course) but for their foliage.  Many develop a reddish colour in the fall.  One perennial that blooms late summer or in the fall, is monkshood (Aconitum).  Mine bloomed in October this year but note that monkshood is a poisonous plant (all parts) so this one may not be for you if you have small children or pets who visit your garden.  The perennial stonecrop (Sedum) or houseleek (Sempervivum species) and annual straw flowers (Xerochrysum bracteatum) never disappoint in fall.  Certainly, the native asters (Symphyotrichum species) and goldenrod (Solidago species), especially when grown side by side, are beautiful as they bloom in the fall garden.

Monkshood
Zinnia

Grasses

I love the grasses, particularly in the fall. Their gold, bronze, copper, red or blue foliage and seed heads, are beautiful as they sway in the breeze.  Blue fescue grass (Festuca glauca) remains a pretty blue year-round which is welcome as the gardening season winds down.  This grass may be short lived but reseeds well.

Blue switch grass ‘Heavy Metal’ (Panicum virgatum) is a taller grass which is good for the back of the border or as a focal point.  It has metallic blue leaves that turn bright yellow in the fall and is accompanied by delicate pink panicles (loose, branching cluster of flowers).

Blue fescue grass

Fall is a good time of year to walk through your garden.  Look at what catches your eye.  If you decide that more colour is needed, perhaps consider some of the choices suggested above for spring planting then texture and colour next fall.   For more information on fall colour in the garden, check here.

Fall is the New Spring…It’s Time to Plant

Leave a comment

by Emma Murphy, Master Gardener

I confess to LOVING this time of year. The heat and humidity of the summer is gone, and our gardens are still looking lovely. Although my established gardens are beginning the slow process of fading and getting settled in for their winter sleep, fall is a wonderful time to plant for so many reasons.

They may not look perfect but they’ll be going to sleep soon and will wake up next spring in their new homes.

You Have Time

Unlike your annuals or tender perennials, most perennials (and native plants in particular) can be planted in September and well into October (depending on where you live in Ontario).

Smaller trees and shrubs in particular are fine to plant once they have gone dormant and leaves have dropped, as long as they are well watered until freeze up.

I love the fall as it seems less frenzied than the spring gardening season, with time to reflect on the summer that has passed. Unlike spring and summer, temperatures moderate during fall, not only for the plants but also for us! It’s terrific working weather – you start with your sweatshirt on in the morning, but by the afternoon the temperatures have warmed up considerably and you might be in a t-shirt. During July and August I can only work in my gardens in the early morning or late evening due to the heat. Your plants don’t like to be planted in the heat of summer either. So fall is my happy time.

Assessing and Dividing

Fall is the perfect time to look around your garden – do you have holes, bad-looking spots, poorly performing plants? Are there places that need something new or something moved?

I need to revamp this garden and think about moving some perennials around.

Fall is a great time to divide overgrown perennials, especially those that bloom in the spring. I just dug up all of my fragrant hostas the other day and moved them to a new location so that I can expand my shade native plant garden. Next up – planting a hedgerow.

Hostas at the front of the bed were removed to put in more native plants

Warmer Soil Temperatures

During fall, soil temperatures remain warm from the summer sun, so conditions are ideal for root growth.

Cooler Air Temperatures

Gone is the humidity and heat of the summer and the unpredictability of spring weather (and worries about frost). Daytime high temperatures are nice and there is less water evaporation from leaves.

More Rain, Less Work

With fall also comes more frequent rainfall and less need to water new plantings. There aren’t crazy swings in moisture levels – fall rains are warm and welcome and moisture levels are perfectly balanced, encouraging root growth.

When you plant in spring and early summer, the weather can be very variable, especially with regard to temperatures and rainfall. The soil is still cool, and plants take a while to get established.

Fall rains rejuvenate our gardens

Some Challenges

It can be challenging to plant new perennials in the fall – stock and selections at nurseries may be less (however the prices may be better!) and some plants have been sitting in plastic pots for months and look less than perfect. Be sure to purchase new plants at a nursery that takes good care of their plants over the gardening season (that generally does not include big box stores – shop local where you can) and pull the plant out and check for a healthy root mass in the pot.

Ideally, give your plants at least 6 weeks of optimal growing weather of fall before the colder winds start blowing in.

One Last Note

It’s a really good idea to add mulch to your fall gardening – it helps insulate the ground and maintains warm soil temperatures even during early winters. So, you are providing a nice warm area for young plants to establish their root systems before the frost.

A Special Note on Native Plants

They might look a little sad in the nursery, with not much top growth and it may be browning. However, under that soil are roots, lots of roots, and that is what you are buying when you purchase a native plant.

Although a bit brown on top, this native plant has great roots
just ready for a new home.

So when you see a small three inch plant with roots coming out the bottom, recognize that it’s the perfect size to plant, and don’t worry about its ability to survive the winter.

Sleep, Creep, Leap

You may have heard the phrase “sleep, creep, leap” with respect to many plants, and especially native plants. Unlike most perennials, native plants just want to get their roots established during the first year (which is why they appear to ‘sleep’).

So if you plant in the fall, the roots are growing furiously, pushing south to grab moisture and nutrients to sustain them through the heat of summer next year. In the second year native plants creep, with more top growth and maybe even flowering. Watch out in the third year! They leap to their full size and blooming capacity.

So, if you can plant in the fall, the sooner your native plants can put down their roots in their new home, and be ready to grow in the spring season.

Bottom line? Fall weather is optimal for growth.

The perfect combo of warm soil temperatures near the root and cooler air temperatures on the top offer the ideal growing conditions for any new plantings or dividing existing perennials.

So get out in your gardens! (It’s also time to think about planting your spring flowering bulbs. Check out Master Gardener Cheryl Harrison’s excellent blog on how to do this.

Make a planting plan now to grow your best vegetable garden yet!

By Silvia Strobl, Master Gardener in Training

True confession: In 30 years of growing a vegetable garden I’ve never made a planting plan. I only make a sketch noting what was grown in each planting bed so that I rotate crops over a 3-year cycle to minimize pest build-up.

Recently, I was introduced to the idea of making a planting plan to both optimize garden space for vegetables to be grown and ensure timely harvests and succession sowing/planting–of particular importance in our short growing season! Now is a great time to plan. To illustrate how, here are the steps to grow 6 crops in a hypothetical garden plot 12 feet x 12 feet in size.

Step 1: Identify the Average Date of Last Spring Frost and Average Date of First Fall Frost for your garden location. By consulting this Ontario map, we see that Peterborough is in Zone E with a May 17 last frost and a September 26 first frost, giving a 19-week or 133-day growing season.

Step 2: Identify the vegetables you want to grow, and note the weeks to maturity (i.e., estimated time before you can harvest edible vegetables) on the seed packet. Decide whether you will direct sow or plant seedling transplants that have either been purchased or sown indoors. In short growing seasons, transplants can give you a head start and are recommended for crops that take more than 100 days to mature.

Step 3: Make a schedule either on paper or in digital format, by creating a table with the months of the growing season as columns and the 4 weeks in each month as rows (see Table 1 or this more detailed worksheet). Identify in which weeks the following events for each crop will occur:

  • Direct sowing of cool season crops like lettuce, spinach, kale and snow peas (second week of April in Peterborough)
  • Either direct sowing or planting of seedling transplants of warm season crops like carrots, beans, squashes, melons, tomatoes (third week of May, or later)
  • Count the weeks to maturity and identify when harvest will occur for each crop
  • Identify if there will be enough weeks in the growing season to sow or plant the space with a second crop of after the first crop is harvested
  • If you can sow or plant a second crop, add these actions to the schedule, ensure the second crop in any planting bed is from another vegetable family
  • Finally, add in other key dates, like when seedling transplants need to be sown indoors in spring and hardened off, or in mid-summer (for a second crop), if growing these yourself

Table 1 shows a schedule for 6 crops and identifies that the growing season in this hypothetical garden can accommodate harvests of two kale, lettuce, and bush bean crops, and one carrot crop.

Step 4: Identify where each crop will be planted by sketching a map to approximate scale of your planting beds. Refer to the recommended spacing on the seed packet, to identify how many plants will be sown or planted. Refer to notes about the past 2 years of planting to ensure you don’t grow the same crop in the same location as the years before.

Figure 1 shows the 12-foot square hypothetical garden divided into 6 beds, each 3 feet by 5 feet. We immediately notice that nothing is planted in beds 4 and 5 until the last week of May and the first week of June, respectively. Could radishes (3 to 5 weeks to maturity) and spinach (5 to 6 weeks) have been planted in mid-April in beds 4 and 5, respectively, and mostly harvested just before planting the small tomato and zucchini seedlings?

Ft.= feet; in.=inches; W/in = within; Wk=week

You will likely grow more than 6 vegetable crops. For example, you could plant seedlings of a short-season broccoli instead of kale crop #1 and snow peas instead of bush bean crop #1. But, if you follow these steps to make a planting plan almost every inch of your garden space will be used from as soon as cool-season crops can be sown to when crops such as kale, cabbages, carrots, and parsnips are touched by the first frosts that concentrate sugar content and improve their taste. You might also include annual flowers like marigolds, calendula and alyssum that not only add beauty to the vegetable garden but attract pollinators.

By recording yields in your garden over the years, the planting plan can be fine-tuned so that the number of plants of each crop grown is as much as your family can eat. Nobody wants to be overwhelmed by too many zucchinis!

It is a bit of work upfront to make a planting plan, but it will save time over the growing season because you will know exactly when and where each crop will be planted, at what spacing, and which crop will succeed the one just harvested. You will also save money by only buying seeds for crops that will be grown!

I am going to try this for my vegetable garden this year, how about you?
