GARDENING WITH MARK AND BEN

May, 2025

May is Planting Month: you ready?


May is a lot of things: flowers after April showers, Mother’s Day and planting month.

It doesn’t really matter what you intend to plant, May and the first half of June, in virtually all parts of Canada, south of the Arctic circle (more or less), is the month to plant plants. Shrubs, trees, evergreens, perennials, veggies and later, frost tender edibles and annual flowering plants.

Plant, plant, plant.  

We encourage you to go for it. And buy early if you can as the best quality stuff comes from the farm first, including the most colourful annual flowers from the greenhouse. For proof, check out the first geraniums to arrive at your retailer then go back in a month and check out the supply. No comparison.

However (and you knew there would be a “however” didn’t you)…. The secret to growing great plants is to invest in a little knowledge and the soil. The root zone of your plants will determine how the top half of any plant will perform. While this sounds obvious, the truth is, most beginning gardeners do not pay enough attention to soil preparation. 


So, that said, here are our 5 essentials for successful planting this spring:

 

1.      Match the plant to the exposure. If your garden or balcony is sunny, design your garden using heat-loving plants. We encourage you to look for plants that can dry out between water applications. The “Sunshine” impatiens that look so good in a hanging basket at the garden center around Mother’s Day are one of the worst choices for placing in a sunny location, despite their name. Their moisture rich stems are loaded with water, and they need to stay that way, or they collapse in front of you. 

Conversely, if you are planting in a shady place, avoid most of the flowering plants that will tempt you and steer your purchasing power towards green: ferns and foliage plants that tolerate low light.

2.      Dig a hole three times wider and 50% deeper than the root mass of the plant and backfill it with quality soil, like triple mix (equal parts soil, peat moss and compost). Place the plant a little deeper in the hole than it exists in the pot you purchased it in don’t be afraid to bury a centimeter of soil around the main stem of the plant. This is only true of perennials and annuals, as shrubs and trees need to have water flow away from their root zone. We recommend that you plant them above the soil grade by a few centimeters and mound quality soil around them, but NOT up the stem or trunk.

3.      Compost. If you have a compost unit or pile, now is the perfect time to remove the finished material and add it to your existing garden soil. It is nutrient rich. Be generous. This is not salt and pepper. If your garden soil is clay based and heavy, add generous quantities of sand to open it up and allow water to move through it freely.  

And when planting in containers, always use new potting mix, not the soil of last year. It will be fine used in your garden (so don’t throw it out). 

4.      Water. Every plant needs water shortly after it has been planted. Even a desert plant like a cactus. For most garden plants, a deep drink that reaches down to the lowest roots of the plant is necessary. Add more water as the top 2 or 3 centimeters of soil dries out. Use your finger to determine this. As the season progresses, pull back on the frequency of water applications.

5.      Mulch. After all your planting is done, mulch around each plant with finely ground up cedar bark about 3 to 5 cm thick.  This will reduce the need for water by up to 70% and reduce weeding up to 90%.

Which reminds us, weeding and watering are essential to the long-term health of your garden. As May turns into June be sure to have an eye out for these important tasks and who knows, maybe this will be the year that you win a community award for the best-looking garden on the street.

We certainly hope so.

A TRUE HONOUR

A few weeks ago, I received a Letter from the Honourable Edith Dumont, Lieutenant Governor of Ontario.

I am deeply honoured to be awarded the King Charles III Coronation Medal. Such an incredible surprise.


Thank You to all involved and to those who nominated me for this prestigious accolade. 


I shared this news on my Facebook page and the response was overwhelming. Thank you to everyone for your kind comments.

Thank you also to team Trees for Life who helped immeasurably to make this happen. They make me look good.

THINGS TO DO THIS MONTH

·      Get Ahead of Insects and Disease with dormant spray. Wait until nighttime temperatures are above freezing for treatment of your trees, shrubs and roses. Apply before the buds have fully broken.

·      Start your zinnias, marigolds, cucumbers, squash and other fast growers or wait another couple weeks and direct sow them outdoors. Always in a sunny garden.

·      Prepare your containers. Containers should be emptied of last year's soil (the old soil spread in the garden) and replaced with quality new container mix. If you live somewhere off the ground, like a condo, give the soil to a friend who owns some real estate (and a garden).

·      Prepare the soil. Meanwhile, back on the ground, enhance the quality of the soil in your garden with generous quantities of compost. We spread two to three centimeters of compost over most of our gardens this time of year.  Let the earth worms "work it in" to the sub soil. You can turn yours under by hand or use a rototiller.

·      Plant. Most Canadians live in a growing zone where frost is expected for at least the next couple of weeks. All of us can plant trees, shrubs, evergreens and roses now. If you find perennials that have not been greenhouse-forced, they can be planted out as well.

·      Sow. Many veggies can be sown by seed now, regardless of frost in the forecast: peas, radishes, beets, carrots, onions, lettuce, broccoli, cabbage, and Brussels sprouts.

BIRDS IN FOCUS:

Birds Canada Birdathon

By Jody Allair

 

For those who have been following along with my column over the years, I’ve written a lot about my favourite yard birds, highlighted conservation issues and provided tips that people can use to help protect and conserve birds at home. This month I want to draw attention to a very important fundraiser – the Birds Canada Birdathon.

 

On Friday May 23rd I will be participating in the Birds Canada Birdathon to raise funds that will help conserve and protect Canada’s wild birds. This year I will be birding around the prairies and badlands near Drumheller Alberta. My big target will be to find our 2025 Avian Ambassador — the Endangered Chestnut-collared Longspur.

I have been taking part in this important fundraiser for over 20 years. All proceeds from the Birdathon help sustain conservation programs and initiatives through Birds Canada that are making a real difference for birds. Proceeds also support the Birds Canada Community Grant, which provides one-year grants for initiatives that enhance the understanding, appreciation, and conservation of birds.

You can donate at: https://www.canadahelps.org/me/ngYdTdj  

All donors will receive a tax receipt along with a summary of my birding highlights.

Good Birding!
