Bringing Spring Indoors

by Emma Murphy, Master Gardener

I’m trying something new today. If you’re like me, you’re going a bit loopy by mid-February. The snow just keeps on falling, you have no more room for new houseplants, and you just want to see some green or flowers. Two years ago I went to visit friends in Florida and it just rejuvenated this gardener’s soul to see the two Gs – green and growth, plus some beautiful flowers like these.

Where was I? (distracted by looking through all my February Florida flower photos!). Back to the blog topic at hand.

Often people force bulbs like paperwhite narcissus, muscari and hyacinths in mid-winter, but in many cases that requires remembering to put the ones that require a cold period in the fridge or other cold spot (and I never remember).

Then I saw someone “forcing” flowering shrub branches and I said “I can do that!”. The key is to cut branches and fake them into thinking it’s spring and time to flower.

Under normal conditions, warming spring temperatures and lengthening days trigger flower buds to swell and open.

The process is fairly straightforward:

  • Head outside in your garden, preferably when the temperatures are above zero Celsius and it is sunny
  • Using sharpened secateurs, look for branches with plump buds and cut branches about a foot or so in length; make sure to use clean pruners and proper cuts to protect the rest of the plant
  • Plunge the branches immediately into a bucket of very warm water inside (about as warm as you can stand on your hands); the water helps move that first burst of moisture up into the stems; some people advise submerging the entire stems in water in a bathtub overnight
  • After 6 hours, make fresh cuts (see next bullet) and move branches to water-filled vases. Use narrow necked vases, bottles, or mason jars to keep the branches standing upright
  • Don’t smash the branch ends (old advice) – make a slit or two in the bottom of the stem so it looks like a cross or star pattern from the bottom.
  • Add floral preservative to the water or 1 tablespoon of antibacterial mouthwash per quart of water to prevent bacteria growth
    • Another option is to leave the cut branches in the original bucket of water until they bloom. Then they can be moved into vases, as needed
  • Keep in a cool area (no more than 18 degrees Celsius/65 degrees F) and in indirect light (warmer temperatures cause buds to develop too rapidly and not open properly and direct sun can cause bud drop)
  • Change the water weekly (adding new preservative). If the water discolours or begins to smell replace it, and in 2 to 4 weeks, the dormant flower and leaf buds should open
  • Mix the blooming branches with a cut evergreen branches for a free bouquet

Branches that are a half-inch or less in diameter work best, as do plants that flower earliest in spring. Make a fresh cut whenever the cut ends are exposed to the air for any reason – that exposure will lead to healing, and when the cut end seals, it can’t take up new water.

Among the best bets? Plants that naturally flower before May – things like fruit trees, lilacs, azaleas, rhododendrons, redbuds, witch hazels, forsythias and magnolias – species that produce their flower buds the year before.

It helps to understand each species’ different “chilling” requirements before buds are in position to open. Chill time occurs at 4 degrees Celsius (40 degrees Fahrenheit) and less. Most spring bloomers are ready to flower after about 6 weeks of chilling, but some late-spring bloomers need eight or 10 weeks*.

* Trees and shrubs suitable for forcing from January on: Cornelian cherry dogwood, filbert, forsythia, fothergilla, witch hazel; from early February on: apple, cherry, crabapple, ornamental pear; from mid-February on: beech, birch, Japanese maple, lilac, magnolia, quince, red maple, serviceberry, willow.

What a perfect way to brighten your house in winter while impressing everyone with your gardening expertise. And best of all it’s free..

I’ll be planting some witch hazel this spring to be ready for next year!

Here’s some other great suggestions from Ottawa Master Gardener Kira Burger on things gardeners can do to keep occupied until the snow melts.

Planning and Dreaming

by Judy Bernard, Master Gardener

Winter is a time for planning and dreaming about our gardens.

Since we decided to move and downsize, I’ve been planning on how I want to create my new garden. Right now, under the snow, is mostly compacted construction zone. Debris from bricks, rocks, and stones ( I’ve collected some of the larger stones for garden beds) and weeds have been partly covered by sand fill. I’m hoping that we will have topsoil and sod fairly early in the spring. In the meantime, I’ve been dreaming and planning.

watercolour-2045917_1920

Our house is oriented east-west. There are two story houses to the north and south of us. Before planning on what shrubs and plants to put in those areas, I want to see how much shade they provide and for how long during the daytime. I’m keeping a record of where the sun is in the sky relative to those areas. The front and back are wide open, like a blank canvas.

summer-4282857_1280

At the same time, I’m making plans for what trees and shrubs I want to put in those areas. My choices are for mostly native shrubs, trees and and fruit producing plants. Other than the usual garden centres, I’ve been looking for places to purchase native plants and have found some close by Peterborough that grow shrubs and trees. Richardson’s Pineneedle Farms in Pontypool is one. They are a major commercial grower and have a lot of native shrubs and trees for sale. You can buy in bulk there. Another one Eastern Evergreen Inc. grows white cedar for hedges and is located in Warkworth.

With an office in downtown Peterborough, Cedar Ontario has a long track record of providing healthy natural eastern white cedar trees and installing hedges throughout Peterborough and the Kawarthas.

When it opens, Ecology Park in Peterborough is another good place to purchase native plants. Their big annual plant sale is Saturday May 16th at 10 am. Remember to bring your own containers for leaf compost and cedar mulch. The bulk sales are self loading , with a 20 bucket limit per person, per visit. Knowledgeable staff and are there to help you (and often Master Gardeners are there too).

In the meantime, I’m researching trees and shrubs, drawing plans, and dreaming.

 

 

I Remember When…

by Mary Jane Parker, Master Gardener

EmmaHayfield

One of my first gardening loves was daylilies. This probably started with Master Gardener Beryl Harris taking me to an open house for “We’re in the Hayfield Now” daylily gardens in Orono, Ontario. And every time I see Henry Lorrain today at my favorite breakfast haunt, I think of how much fun those open houses were. They were like the social event of my gardening season and I know many others who felt the same way.

Henry and his then partner, Doug Lycett (who has since died), knew all of the renowned hybridizers of the time – mostly people from the eastern U.S. right down to Florida. Henry and Doug were probably the premier hybridizers in Canada, if not the only ones when I first discovered daylilies. Those were heady times. Hybridizers were aiming for ruffles and frills, picotees and edges, rebloomers and the colour blue, among other things. There are 390 cultivars registered to Lycett, Lorrain/Lycett and Lorrain.

20200103_205956

Collectively these peoples’ daylilies created the genetics for generations of daylilies and encapsulated the best of the best. still have early plants from Henry and other key hybridizers.

Kudos Henry. We owe you!

Facing Climate Change: What Gardeners Need to Know

By Sharleen Pratt, Master Gardener

I recently attended a Master Gardener’s Technical Update at the Toronto Botanical Gardens. The subject was Facing Climate Change: What Gardeners Need to Know. The speakers were Dr. Jon Warland, Dr. Steven Hill and Lorraine Johnson. As we sat listening to how our climate is changing and the impacts that this has on current gardening practices, it was not lost to us that we were about to experience an upcoming ice storm at the same time that Australia was dealing with horrific fires. And then on January 17th, Newfoundland is hit with one of the worst winter storms they have ever had!

Some interesting facts I took away with me that day were:

  • Plants that were once borderline hardy are now easily surviving our winters.
  • Severe storm conditions are damaging many of our trees.
  • The Sugar Maple could disappear in this century from the Greenbelt area.
  • Invasive plants are taking hold and pushing out some of our woodland native plants.
  • The average concentration of CO2 in the atmosphere was about 250 parts per million (ppm) in pre-industrial times. Now it exceeds 400 parts per million (ppm).
  • The peak bloom date for cherry trees in Washington, D.C. has shifted earlier by approximately five days since 1921.
  • The current climate in the Golden Horseshoe area will be in Algonquin Park by the end of the century.

Lorraine Johnson spoke at great length about our perception of what was a ‘nice’ garden. She believes that we need to understand the benefits of growing native plants that will be hardy enough to withstand the unpredictable extremes in climate. She presented several examples of people who had replaced their front lawns with native plants or vegetables and had been instructed by the cities to remove the plants or had received bills when the city moved in and cut it all down only because it was considered ‘messy’ and ‘unappealing’!

What we can do as gardeners:

  • Consider using native plants. You will be rewarded with lots of birds, butterflies and insects to help cultivate a natural ecosystem.
  • Grow as many plants as possible (I won’t have a problem with this one). Gardening is a journey and learning what plants work best in your conditions takes time and patience.
  • Learn to live with some weeds, nibbles in leaves, as well as leaf spots. Focus on cultivating plant health.
  • Stop watering your lawns as it is estimated that nearly one-third of all residential water is lost in the watering of lawns. Your lawns will go dormant in dry periods but will return with the fall rains.
  • Consider a rain garden to minimize surface runoff.
  • Include a diverse mix of plants, shrubs and trees to prepare for the possibility of losing certain plants due to climate change.
  • Leave grass clippings on your lawn to add nutrients
  • Mulch fall leaves and add to your lawn or flower beds to avoid having leaves sent to the landfill where the organic material undergoes anaerobic (without oxygen) decomposition that produces the greenhouse gas methane with is worse than CO2.
  • Grow your own vegetables or buy locally from farmers markets to help reduce greenhouse gases when food travels thousands of kilometres from farm to grocery store.
  • MOST IMPORTANT … Get out in your gardens and be thankful for the beauty that surrounds you!

African Violets – Houseplant Extraordinaire!

By Cheryl Harrison, Master Gardener

African violets are the plants that immediately come to mind when anyone asks me about houseplants. This plant is an old favourite for good reason. I have two. As the name implies, African violets are native to the cloud forests in the mountains of east Africa. Many of the native plants are threatened or endangered due to habitat loss. African violets are not violets (family Violaceae, genus Viola) but are included in the family Gesneriaceae, genus Saintpaulia.

African violets are classified by size from the “Mini” which are less than 7.6 cm (3 inches) in above-ground diameter to the “Giant” which ranges from 30.5 cm – 40.6 cm(12-16 inches). They are pretty plants even when not in flower which they will do almost continuously under good growing conditions. Their flowers may be single, semi-double or even double. This refers to the rows of petals on the flowers. Flower colours include blue/violet, pink, fuchsia, white and bi-coloured. Their dark, green leaves appear velvety because they have a fleshy texture and are covered with fine hairs. The plants maintain a compact form but do come in a trailing form. Lots of choices!

Picture1

African violets prefer soil that has excellent drainage because the plant may rot if water lays on top or the soil stays water logged. You may purchase specific African violet soil to help ensure a porous growing medium that allows water to percolate through.

Water your plant so that the soil stays moist all of the time but pour off the standing water from the saucer under the plant to prevent the soil from becoming water logged. Do not get water on the leaves of this plant because disfiguring rings will appear where the leaf has been damaged. You may also use a system that allows you to water your African violet from the bottom. This can be as simple as filling the saucer under your plant with water then allowing the plant to absorb water from the saucer. Discard any water left in the sauce after about 45 minutes. Remember to check the surface of the soil to make sure that it is moist … if not, then repeat this process. There are also self-watering pots available. Over-watering or under-watering will damage and may eventually kill your plant.

Picture2African violets like bright indirect light. A sunny, warm window is okay in winter but in summer, place your plant in a north or east window or just sit it back from a south or west window so that it does not receive direct sunlight. African violets prefer cooler temperatures at night around18C (60F) and up to 27-29C (80-85F) in the day. Too cool temperatures will stunt their growth.

Like any houseplant, African violets can suffer from some diseases and insect pests including botrytis blight, powdery mildew, mites, mealybug, aphids or thrips. Be sure to purchase your African violet and all of your house plants from a reputable seller to avoid these problems.

With all of the new African violet cultivars and their colourful blooms, why not try one? If you enjoy house plants then the African violet may be the one for you!

Permaculture: Where do I start?

By Suzanne Seryck, Master Gardener

So what do gardeners do in the winter? Once we’ve read all our seed magazines and compiled our purchasing lists, or designed new or changes to existing perennial beds, or decided on our vegetable crop rotation for the upcoming season, or read a new gardening book, or watched some gardening videos or TED talks, or found ourselves in the middle of taking a gardening course, what next? Personally, once I’ve exhausted all these possibilities, I tend to reread my favourite gardening books. I have an incredibly bad memory and find it really helps me when I reread the same books over and over; hoping eventually something will sink in. My books to reread this year are both permaculture-related: Toby Hemingway’s “Gaia’s Garden” and Rosemary Morrow’s “Earth User’s Guide to Permaculture”.

When I first became interested in permaculture a number of years ago, I started reading books and watching videos by the two founders, Australians Bill Mollison and David Holmgren. The concept, ethics, and principles resonated with me, but I have to admit that I struggled based on the literature available at that time, to understand how to translate this into my own Canadian garden. It was not until a couple of years later that I attended a couple of local permaculture design courses and read the book by Toby Hemingway who focuses on North American gardens, that I felt confident enough to bring some of those concepts and methods into my home garden

As I mentioned in my last blog, permaculture is a design system, a set of guidelines, principles and practices for sustainable living and land use, working with nature in a continuous cycle that benefits both people and wildlife. As with anything new or overwhelming, it is easy to be deterred by the big picture.  Instead, focus on smaller ideas or concepts. If you start implementing smaller more manageable tasks, it will give you confidence to tackle the larger concepts.

The following are a few easy-to-implement permaculture techniques to get you started:

  1. Sheet mulching. This was actually the first group activity I performed in my first design course.  It can also be called lasagna gardening. Permaculture encompasses a no-dig philosophy focusing on building soil life. Sheet mulching allows you to create new beds whilst eliminating weeds and building up the health of the soil. It is also a lot healthier on your back. You simply lay a heavy layer of newspaper or cardboard over the area and top it with 12 inches or so of organic mulch.
  2. Keyhole garden beds. Keyhole beds are often used in permaculture because they maximize use of space, whilst building soil fertility.  They decrease irrigation needs and are easy to plant, harvest and maintain. The bed can be either raised or not, and is often created in a circular pattern which decreases the space required for paths and increases space for plants. This type of bed is most often used for growing herbs & vegetables and because of the circular design, plants with different growing requirements can be planted together often creating different microclimates. For more information: https://permaculturefoodforest.wordpress.com/2016/04/14/keyhole-gardens/
  3. Creating gardening communities or guilds. In permaculture, a guild can be defined as a grouping of plants, trees, animals and insects that work together protecting their health, habitat and productivity. Probably one of the most familiar guilds is the Three Sisters Guild in which squash, corn and beans are grown together; each one supporting and benefiting the others. The beans grow up the corn and provide nitrogen, whilst the squash mulches and covers the soil. In my last garden, I grew apple tree guilds, surrounding each apple tree with daffodils in the spring (deter predators from chewing bark), comfrey and yarrow, and herbs such as dill & fennel along with chives & onions.
  4. Multiple stories or forest gardens. As an avid gardener and someone who has difficulty saying ‘enough is enough’ when it comes to plants–and also the owner of a small city garden–this technique is one I am especially interested in. The idea is that a garden can have multiple stories or layers; from a low herb or ground cover layer up to perennials, shrubs, small trees and finally the canopy trees. The plants in each layer combine and support each other to create and maintain a healthy ecosystem.

Permaculture is much more than the simple examples I have given.  It can encompass everything from designing landscapes and buildings, to water and waste management. The benefits for me include enriching the land, feeding and providing habitat, growing food for my family, and giving me somewhere to unwind and feel good about life. However, I am omitting one very important benefit for myself–by incorporating some permaculture practices into my garden, the garden tends to look after itself much more with less interference and work for me!

Thank goodness the seed catalogues have arrived…

By Mary-Jane Pilgrim, Master Gardener

“Thank goodness the seed catalogues have arrived… I was about to start cleaning my house!”

It starts with the dream.

There’s no better time than now to  dive into a good seed catalogue and start planning for the upcoming growing season. Seed catalogues can be a great resource for bulbs and unique seeds, and offer a far bigger selection than what you can find in your local garden centre. You’ll find inspiration and will likely discover new plants that you must have in your 2020 garden.

You’ll be the most successful if you pick the seed companies that are closest to where you live, or in the same growing region as you. However, you can still have success ordering from a company farther away, but you’ll have to be careful not to order a plant that isn’t in your growing zone.

Below are some popular seed companies from across Canada, with some that are also in close proximity to the Peterborough, ON, area.

Gardening Resolutions for A New Year

by Emma Murphy, Master Gardener

As this decade comes to a close, I like to think that I over the past ten years that have learned some things about gardening. And with that in mind, I’ve set a few New Year’s resolutions to guide me through this next year (and decade).

1. Be Better at Cleaning My Tools

I have some great tools – my Felco #12 secateurs/pruners (several pairs), my delightful drain spade, and my Japanese hori hori knife. But I am neglectful and do not clean these well during the season and especially at the end of the gardening year. My resolution to improve my tool maintenance for next year. Some guidance here and here.

20190713_140635

2. Make a Plan

I was basically back to square one in my garden a few years ago after a major house renovation. Since then we have installed some hardscaping and I have tried to replan my gardens. I’m 15 years older than when I first did my gardens, so my plan needs to take into account my aging and energy level, so I have eliminated those fussy perennials and focused more on a garden built on flowering shrubs that are lower maintenance. But I don’t have a plan, and my engineer husband keeps saying “where’s the plan?”. So my resolution is to spend this January laying out a plan for spring, rather than just going with my gut.

gardenplan

3. Don’t Order Too Many Seeds

This will be a tough one. After all who hasn’t looked out their window in January at the snowy landscape while reviewing seed catalogues and dreaming of a perfect garden? The diversity available via seed companies is just astonishing these days, and it’s nice to grow something that your friends don’t have and that you can keep seed for the next year! But we all tend to indulge and over purchase, so my resolution is to have a specific place for any seeds that I order (see previous note for a plan), and to test all the existing seeds I have for viability like this.

4. Share my Knowledge and Start a Blog

While I write a blog for the Peterborough Master Gardeners on a regular basis, I’d like to start a garden blog of my own. The challenge? Just finding the time when I work full time and write for a living. My resolution is to spend January getting a basic blog set up, and then to try and write once a week starting in February. I’ll share a link once it’s up and running, and you can all hold me to task for getting it off the ground. The great part is there is lots of good advice on how to start a blog out there.

Create a Holistic Garden

I am passionate that my garden should be more than just beautiful flowers – it should be a wonderful habitat for birds and bugs and critters and pollinators, and everything in between. I want to know that I am making a difference that contributes to supporting our local ecology and habitat. My resolution is to continue focusing on this as I re-establish my garden, and share my knowledge with others so that we can all make a difference.

Wishing everyone a Happy New Year and a wonderful 2020 gardening season, wherever you may be.

Last Minute Festive Plant Care Tips

by Christine Freeburn, Master Gardener

Christmas is only a few days away and hopefully you have all your cookies baked, your shopping done, presents wrapped under the tree and your decorations up. Here are a few last minute tips to help you and your plants through the next week.

If you are taking plants to family or friends, bundle them up before putting in a warm car so they won’t be shocked from the drastic temperatures. If you buy a poinsettia, be sure the clerk wraps it well as they are very susceptible to drafts. If you are taking the plant home before you give it away, remove the paper or plastic wrapper to let the plant breathe once you get it into the warmth of your home. Check the soil to be sure it is damp and water if necessary. The same applies to any arrangement you might be transporting. Keep warm and watered so the plants are happy.

DSCN7188

If you have leftover cut evergreen pieces, now is the time to use them up. BC cedar and Ontario white pine look the nicest. Make little arrangements for in your bathroom either in oasis or in water. Place stems in vases along with fresh flowers. Lay fresh greens on mantles, side tables or your dinner table. Add stems around your amaryllis bulb or with your paperwhites. You can purchase a WiltProof product which when sprayed sparingly on fresh greens, will prolong their life. Please be mindful of fire hazards when you are decorating with fresh greens.

And have a Merry Christmas and a Happy Holiday Season!

The Christmas Rose: Helleborus niger

By Judy Bernard, Master Gardener

Nothing warms a home up as much as plants do. At this time of the year there are so many options to choose from: Poinsettias ranging in colour from white to deep reds, Cyclamen, Christmas Cactus, Amaryllis, Rosemary to name a few. There is one, however, that is usually found in garden centres in the spring but which one can occasionally find in a grocery store or florist in the fall, and that is the Christmas Rose. Its botanical name is Helleborus niger and its common name is Hellebore.

Helleborus niger is a hardy perennial in the Raniculaceae or buttercup family. It has dark green evergreen foliage and delicate white flowers resembling a wild rose. They are hardy to zones 3-4. Bloom times vary from November to February/March, depending on the location. They like semi-shade and grow well in sheltered areas in well-draining soils.

If you are fortunate enough to find one in your local store, not only will you have a conversation piece, you will be able to plant it outside in your garden and enjoy it for many years.
