Compost, Perennials, Pruning, Shrubs & Trees, Soil

Some tasks to get started on now…

By MJ Pilgrim, Master Gardener

Spring is just starting to peek through the winter cold and soon it will soon be time to start getting your hands dirty again. Before you break out your trusty garden tools and seed packets, there are a few garden chores you need to tackle to get your garden off on the right foot.

Inspect Raised Garden Beds: Check garden beds for any damage. Over the winter, rain, snow and ice can damage the wood frames of a raised garden bed. Repair or replace as necessary.

Check Your Garden Tools: Get your garden tools a good wipe down and inspect for rust on the tool heads. Oil and sharpen if necessary, paying particular attention to wooden handles that show signs of splits or cracks; rub them down with boiled linseed oil.

fresh-2386786_640Turn Your Compost: It’s time to turn your compost pile and check for any that is black and crumbly and thus ready to use. Making your own compost is free and a great way to amend your soil! Add compost to improve soil by scratching in finished compost into the top one inch of soil.

Top Dress Garden Beds: If you run short of home-grown compost, use well-seasoned manure to top-dress your garden beds in preparation for planting. If you planted a winter cover crop, now is the time to dig it into the soil in preparation for planting the beds.

Plan to Divide Perennials: Spring is a great time to think about dividing or moving plants around as you walk around your gardens.  Any plant that has gotten too large or that has a bare spot in the centre is a good candidate.   Sharing is a cost-efficient way to add more plants to your landscape, but be mindful of pests, disease, and weeds. Only share plants from your garden that are healthy and inspect plants from friends or plant sales thoroughly. If there are any signs of distress or discoloration, do not plant it in your garden.

Weed and Mulch: Eradicate those pesky early spring weeds (or late fall weeds that didn’t get attention) before they get too comfortable in your garden. Be careful of where you step as it will compact the spring soil.  Remove any young weeds first and then put down a layer of mulch. Alternatively, you can plant your garden tightly with perennials, annuals, trees, and shrubs to crowd out weeds. Leaving bare earth anywhere is a recipe for a weed-infested space!

Prune: Remove any dead branches from shrubs, trees and perennial foliage after new growth has begun. Prune the spring bloomers, like forsythia and rhododendrons, as needed soon after flowering is complete. Thin and shape hedges after the first flush of new spring growth.

Taking the time now to complete a few essential spring garden tasks will bring you benefits for the rest of the season.

Bees & Pollinators

What is a “Bee City”?

Leave a comment

By Suzanne Seryck, Master Gardener

beecitycanIn the summer of 2017 the City of Kawartha Lakes was officially recognized as a Bee City by Bee City Canada. I live in Lindsay and heard this first through our local newsletter last summer. Since then I attended our local horticultural meeting in January and heard Susan Blayney, who had spearheaded the project, give an interesting and enthusiastic talk on what exactly this means to the City of Kawartha Lakes and how a city can officially become a Bee City.

Pollinators are vital. They are responsible for 1 in every 3 bites of food that we eat, as well as the reproduction of 90% of the world’s wild life plant species. The approach of Bee City Canada is to bring first nations, cities, campuses, schools and communities together to promote and protect pollinators, encouraging a natural, pollinator friendly approach to gardening and farming, where ecology is respected and biodiversity is the goal.

Bee City Canada was launched in Canada in 2016 by Shelly Candel after being inspired bnature-3240902_640y the success of Bee City USA. Bee City USA is a non-profit organization, which was started in 2012 to help motivate communities to sustain pollinators. There are currently 62 cities and 33 campuses or educational institutes recognized through Bee City U.S.A.

The official vision of Bee City Canada is ‘Communities across Canada, connected in the protection, promotion and celebration of pollinators, enjoying the benefits of healthy ecosystems’. The first city to be recognized by Bee City Canada was Toronto in 2016, and since then 10 additional cities, 8 schools and 3 businesses have been recognized. The City of Kawartha Lakes is the first municipality to be recognized, and is unique for both its size and its agricultural component.

lavender-1537694_640The City of Kawartha Lakes has a number of initiatives that they are working towards, the largest being the Fenelon Falls Pollinator project. Last year, a 1.5 acre decommissioned parcel of land on the Fenelon Falls landfill site was reseeded with a pollinator friendly seed mix. This project is an ongoing pilot that is being monitored by students from Fleming College along with the Ministry of the Environment. Other initiatives that are being planned include pollinator gardens, a 100 garden challenge, education in schools and seed bombing along trails, roads and parks.

It is important for all of us to recognize how necessary pollinators are, and to do whatever we can to encourage and support them. For anyone with a garden, we can all create pollinator friendly spaces, growing plants that will provide food, creating shelter, leaving space undisturbed for pollinators to build nests in the soil and creating a safe, pesticide free environment.

Young Seedlings & “Damping Off”

Leave a comment

By Christine Freeburn, Master Gardener

There is nothing more disheartening than checking your freshly sprouted seeds to discover them rotted and almost dead. Damping Off is a fungal disease that often kills young seedlings. There are several fungi that are responsible, however the most common ones are soil-borne.

Damping off can be identified by these symptoms:

seedling-1386653__340
Seedling 1386653 by Alex80, 2016, used under CC0 1.0.
  • wilted leaves while soil is moist
  • rotten mushy seedlings
  • roots that have rotted off
  • stems that have thin, brown, almost transparent sections
  • white mold, almost cobweb-like on plant stems or surface of soil

Here are some tips to prevent this disease:

  • don’t plant seeds too closely together – plants need air to be healthy
  • fill container to top with soil, so seedlings grow up where air circulates
  • keep air circulating around the young seedlings – do not cover
  • water from the bottom with room temperature water
  • do not let container sit in water – no waterlogged soil
  • use good sterilized seed starting soil and clean containers
  • keep seedlings warm – cool wet conditions are where fungi thrive
  • apply a natural fungicide like a weak solution of chamomile tea

Basically, the best solution to controlling damping off is to give your young seedlings the best soil, watering techniques, and temperature control to ensure success.

Seeds: All of the Dirt

Spring is almost here!

The seed catalogues have arrived and been perused. Seed varieties have been chosen and ordered. Or not. It’s not too late. It’s almost never too late to buy and plant seeds as different things can be planted almost throughout the growing season.

In addition to Canadian gardening catalogues, you can buy seeds at hardware stores and garden centres. If you are looking for something different, Seedy Saturday or Seedy Sunday is a good option. In Peterborough, it is held on the second Sunday in March at the Emmanuel United (formerly George Street United) Church basement. Many local growers grow their own seeds including many heritage varieties and share/sell the extras they don’t need. There is also the Peterborough Garden Show in April where you can buy seeds not generally available elsewhere.

Let’s get started:

You can buy soil specially prepared for starting seeds. It had the best texture for small seeds to be able to put down roots. The soil should be damp like a wrung-out sponge. Using clean containers, fill them with the potting soil. Read the package carefully for the needs of the seeds. Label your seeds carefully so you will know what you are growing.

Spread the seeds on top of the soil, and then add a dusting of the soil mixture using a sieve to the recommended depth on the package for small seeds. Larger seeds can be pushed gently into the soil. Gently pat the soil, so the seeds are in good contact with the soil. Spray the top of the soil with water. Place a plastic cover lightly over the seeds, allowing for some air circulation.

Some seeds need light to germinate, others don’t. Again, follow the directions. Seeds germinate best with a little heat. The top of the refrigerator is a good place to put them. Once the seeds have their second pair of leaves they can be transplanted into bigger containers. The nice thing about starting seeds indoors is that it can extend the growing season for you and give you many vegetables (or flowers) earlier than you would otherwise have if you just planted them directly. Other plants like tomatoes and peppers need to be started early as they have a longer growing season for them to mature before frost takes them.

Here are some interesting websites which including Starting and Planting calendars:

The Right Way to Plant Trees, Shrubs and Other Plants

Leave a comment

by Lee Edwards, Master Gardener

The task of planting is among the many tasks avid gardeners faces every season. Therefore, we’ll focus on the proper way to plant trees, shrubs and plants thereby reducing transplant stress while promoting lush, healthy, plants and root growth.ecology-2985781_640

1. Dig A Proper Hole

To achieve the correct hole size that allows a plant, tree or shrub’s roots to stretch out, dig a hole wider than the width of the plant’s container; about two to two and a half times wider, and as deep as but not deeper than the container’s depth. Then, water the hole.

2. Remove Plant From Container

Ease the plant from its container, gently pushing up from the bottom. If roots are densely packed outside the container (rootbound), loosen the roots before removing the plant. Do not pull on the plant’s trunk, stem or branches when removing from the container, as this may severely damage the plant.

3. Inspect and Prune

Once out of the container, inspect the plant thoroughly. Prune damaged, girdling (circling), dying roots, and suckers. Water the roots, wrap with moist paper, and place in a shaded area away from the wind until ready to plant (same day). If you plan to plant in a few days, cover the paper with mulch and water thoroughly.

For bareroot plants, prune, completely wet then wrap roots, and keep shaded until roots are fully hydrated. For burlapped and dug plants, cut away burlap/wires, prune, wet then wrap roots, and keep shaded until ready to plant.

4. Prepare Soil

gardening-690940_640.jpgSoil is important. Use the soil that was dug from the hole and amend it as needed; for example, add loamy soil to clay soil to ease denseness, or organic matter to sandy soil to slow the soil draining quickly. Ensure the soil is suitable for the plant being planted with sufficient nutrients to satisfactorily support and sustain the plant.

5. Plant Properly

The depth a plant is planted is important. If a plant’s crown is too far below soil level, stunted growth or crown rot may occur. A crown planted too high above soil level may cause sunscald and unnecessary drying out.

Place the plant in the pre-dampened hole and spread out its roots. Make sure the roots sit on firm soil with the crown slightly above soil level to safeguard the crown from sinking below soil level after watering. Fill the hole halfway with soil and tamp down with your hands. Water thoroughly to remove any air pockets. Fill the hole with the rest of the soil and create a shallow, bowl shape at soil level around the plant. Tamp down firmly.

6. Water and Mulch

To reduce transplant stress, water the roots slowly and thoroughly allowing the water to completely sink down and around the roots. Add mulch as needed to maintain moisture then water again. For the next six weeks, regularly water taking care not to allow the soil to dry out.

Reblooming an Amaryllis Bulb

Leave a comment

By Sharleen Pratt, Master Gardener (in Training)

Amaryllis Bulb in its 3rd Year

Amaryllis bulbs are a wonderful winter flower! They never disappoint and are easy to grow over the Christmas season. They come in many dramatic colours. The bigger the bulb, the bigger the bloom, so it is always a good idea to spend a little more to get a good sized bulb.

They are prized for their exotic trumpet-shaped flowers that sit on top of leafless stalks or “scapes”. They are native to Peru and South Africa. The bulbs were brought to Europe in the 1700s. In warmer climates, they have been known to bloom for 75 years.

In Canada, we generally buy new bulbs each year, but did you know that it is possible to keep these bulbs from year-to-year and it is relatively easy to get them to re-bloom. Below is a simple guide to what works for me, but I have also attached a few reliable articles. The methods are a little different, but with the same end result.

 

HOW TO GET YOUR AMARYLLIS TO RE-BLOOM

  • Wait until the amaryllis finishes blooming.
  • Remove the wilted flowers and allow the stalk to die back a little to feed the bulb, then cut it down. Leave any leaves as they also help to feed the bulb.
  • When all chance of frost has past, take your amaryllis outside in the pot and place it in a protected area. It is best to choose a spot that gets morning sun rather than the scorching sun of the afternoon.
  • If you wish, you can also remove it from the pot and plant it in the garden. I tend to leave it in the pot as I find there is less chance of infection from disease.
  • During the summer months, feed it with an all purpose fertilizer about once a month. To be honest, I don’t always remember to do this! If we have a really hot summer, you may actually get another bloom during the summer season. I had this happen two summers ago.
  • Around Thanksgiving, before a hard frost, remove the bulb from the ground or the pot.
  • Cut all the foliage back, close to the bulb.
  • Dry the bulb well (this is important), outside if it’s sunny or in a nice sunny window.
  • Once it is good and dry, put the bulb in a brown paper bag and store it in a cool, dry place. I store mine in the back of the garage up against the house.
  • Leave it for at least 6 weeks.
  • Bring it back in, pot it up in good potting soil. Don’t use a pot that is too large as they like to be snug. Remember to leave the top 1/3 out of the soil.
  • Put in some good supports, fertilize with an all purpose fertilizer at ½ strength, keep it watered but not too wet and ‘cross your fingers’.
  • Indirect light is best until you see some growth, then move it to where you normally keep your amaryllis.
  • You may find that you will get leaf growth first, but eventually you should see a stalk emerge.
  • I have found that you tend to get flowers closer to the end of January, which is a real treat in the middle of winter. If you prefer to have them earlier, start the process before Thanksgiving.
  • Good luck!!

by Cauleen Viscoff, Master Gardener

1. The Informed Gardener – Linda Chalker-Scott

51XOwySYW6L._SX304_BO1,204,203,200_Debunking many anecdotal garden myths, this book is backed by scientific research. Boring, it isn’t. It is charming and witty with a no-nonsense approach. Ms. Chalker-Scott is a passionate professor whose life work is devoted to raising consciousness about marketing misconceptions so we can garden with intention and confidence in an environmental and sustainable way. (paperback – $20.00)

2. The Informed Gardener Blooms Again – Linda Chalker-Scott

9780295990019I learned so much from her first book, I bought this one and was not disappointed. She surprises, teaches and makes sense. (pp. $20.00)

weeds3. Weeds: in Defence of Nature’s Most Unloved Plant – Richard Mabey

This book is readable, informative, and also charming but in another way. He takes us through the life of some plants and seeds we call weeds, showing why we do, where they came from and that many have been here for many centuries. He shows how they travel thousands of miles on ships, in ballast, on animals and in other unmentionables. This is a book to read…and to learn, of course… loved it. (pp $20.00)

4. The Wild Garden (expanded edition) – William Robinson and Rick Darkewild garden

This is such a pleasure to read; it begs a snowy afternoon and a pot of tea. Originally written in 1870, Robinson works to teach formal gardeners to let some “wild” creep into English gardens. He travelled the world to do so. This book has been updated at least 4 times and this edition, with beautiful new photos, includes the original chapters and engravings. Readable, educational and well worth the price. (Hardcover – $71.00- softcover – $10 less)

The Evolution of Gardening

Leave a comment

By Amy Woodward, Peterborough Master Gardener

Last year I went to the Master Gardener Technical Update at Toronto Botanical Gardens.  One of the keynote speakers was Mark Cullen and he was discussing how Canadian Gardening has evolved.  The way we garden is constantly changing by utilizing small spaces, composting and appreciating insects and the natural environment.

Gardening Spaces

Many in urban areas are limited to the space they can garden in.  There are numerous examples of minimal space gardens such as in apartments, community allotments, rental properties and new homes with smaller yards.  A change in my gardening pattern has been from the old fashion long vegetable rows to square foot gardening.   Mel Bartholomew, creator of square foot gardening, was disenchanted with long rows that took up too much space and involved too much weeding.  He came up with the square foot method of gardening that takes up much less space, less weeding and minimal maintenance.  This method is very popular amongst our Master Gardener Organization and for those short on space.  Other approaches to limited space are container gardening, rooftop gardening and lasagna layering.

Composting

Although composting has been around for many years, we have seen changes in the way people compost.  For instance, in the past, leaves were known as a nuisance and people would rake them, bag them and wait for the municipality to pick them up.  Now it is recognized that leaves are a great addition to the compost pile.  Leaves are rich in carbon and balance out nitrogen rich green material.  You can also use leaves as mulch.  Simply rake leaves onto the garden and the leaves will keep the moisture in and weeds out.  Leafs are also used to improve soil texture and encourage earth worms to reside there.

Pollinators

 

nature-3076891_640

The public is now more educated and interested in how to save native pollinators such as flies, wasps, beetles, birds, butterflies and most importantly bees. Unfortunately, pollinator populations are decreasing.  A number of steps have been adopted to protect pollinators including choosing native plants, planting milkweed, decreasing pesticides and installing insect hotels.  The critical role that pollinators play is why the public is so concerned and methods of gardening are changing.

 

 

Overall, gardening continues to change and evolve.  It will be interesting to see what our future has in store for us.

Perennial Plant of the Year 2018: Allium ‘Millenium’

Leave a comment

Adapted from perennialplant.org allium millenium

Allium ‘Millenium’ has numerous virtues to add to the landscape setting and will not disappoint.  It boasts low-maintenance,  dependability, and is not invasive.

Soil: Grows best in well-drained soils.

Uses: Full-sun gardens–where its sleek structure can complement many other growth habits. Cut flowers retain a blush of their summer color.

Unique Qualities: Allium ‘Millenium’ is a butterfly magnet. The plant is interesting through multiple seasons for both foliage and large, gorgeous blooms. Reseeding is much less a problem than in other alliums.

Maintenance: Allium ‘Millenium’ is subject to no serious insect or disease problems. Deer and rabbits usually avoid ‘Millenium’.  Alliums are bulbs that are available in stores for fall planting.

Growing best in full sun, each plant typically produces an upright foliage clump of grass-like, glossy deep green leaves reaching 10-15” tall in spring. In midsummer, two to three flower scapes rise above the foliage with each scape producing two or three showy two-inch spherical umbels of rose-purple florets that last as long as four weeks. Alliums are sometimes avoided due to their reseeding behavior. Fortunately, ‘Millenium’ exhibits 50% reduced seed production, raising less concern for self-sown seedlings.

Blooming at a time when most of our garden begins to decline in the tired excess of the season, ‘Millenium’ offers much needed color.  It is truly an all-season plant that offers attractive shiny foliage spring through summer and caps off the season with its crown of perfectly round rose-purple flower umbels.

Got the Winter Road Salt Blues? Some Advice on What to Plant

1 Comment

by Emma Murphy, Master Gardener (Twitter @Hey_MzEmma)

It’s an unfortunate reality. We live in Canada and we get snow, lots of snow. And then there’s the ice. So our industrious public works folks are out there putting down road salt (sodium chloride) and sand to keep us moving. We also apply salt or sand on paths and walkways on our property. Unfortunately it seeps into the soil and kills plant roots. Road salt mixed with melted snow creates a mist that blows on to our properties, especially when cars splash through melted snow. Having lost a few very nice plants to a combination of huge snowbanks and road salt, I was curious about what plants can survive (and maybe flourish) in a front garden that inevitably gets doused in road salt.

What Does Road Salt Do?

The negative effects of road salt on humans and the natural environment have been well documented. The Smithsonian magazine has two great articles on the subject.
The Hidden Dangers of Road Salt  What Happens to All the Salt We Dump on the Roads? 

Road salt doesn’t just dissolve into thin air. It splits into sodium and chloride ions and gets absorbed into roadside plants, licked up by wildlife or accumulates in aquatic ecosystems—sometimes with devastating consequences. All that saltiness can help invasive or even toxic species spread, not to mention increase traffic danger due to deer and moose drawn to salt-covered roads. (From a gardening perspective, if you want to deep dive into the nasty things that happen to soil structure from salts, this article by the Soil Science Society of America provides some great insight.)

What Perennials Can Handle Road Salt?

Our Savvy Gardening friend Tara Nolan (@ThatTaraNolan) (who you may remember as a speaker from our 2017 Peterborough Garden Show) recently posted a great blog post on how we can combat the road salt challenge in our gardens.

Salt-tolerant Plants that will Survive in Road Salt-laced Soil

So what are some of Tara’s favourites salt-resistant plants?

Autumn Joy Stonecrop (Sedum spectabile ‘Autumn Joy’)
Butterfly weed (Asclepias tuberosa)
Blanket Flower (Gaillardia)
Russian sage (Perovskia atriplicifolia)
Columbine (Aquilegia)
‘Karl Foerster’ reed grass (Calmagrostis acutifolia ‘Karl Foerster’)
Silver mound Artemisia (Artemisia schmidtiana Silver Mound)

Some other ones I found doing an Internet search:

Rugosa roses (Rosa rugosa)
Lilacs (Syringa vulgaris)
Summersweet (Clethra alnifolia)
Lady’s Mantle (Alchemilla mollis)
Daylilies (Hemerocallis)
Catmint (Nepeta)

So, if your garden is looking less than wonderful due to winter salt damage, try some of these options!
