GARDENING WITH MARK AND BEN

May, 2026

Birds of a Feather


Early May on a gardener's calendar and the #1 question is “where do I start?!”

We hope to help you with that this morning, but first a family story.

 

Ben has a farm in Flesherton, Ontario. It is more nature-reserve than cultivated fields, which is the way he wants it. His “family” farm is a summer place.  Ben, being a generally welcoming kind of guy, liked the idea of hosting some birds to the property. Specifically, flying insectivores. Birds that follow the insect trail from south to north every spring. 

The tree swallow is a classic example of an insectivore that needs some friends like us. As a member of the “swift” family, as in chimney swift, they are in decline across the continent. Why? Mostly because insects are in decline, despite what you might think during mosquito season. We need tree and barn swallows, chimney swifts and purple martins to help balance the web of nature, which is seriously out of whack mostly due to climate change and human activity.

Ben working hard! And yes, that is snow.

The answer is to provide habitat for them when they arrive from the deep south each spring. We placed 15 new nesting boxes for them on the farm just a week ago. As you can see from the pictures, it was a family affair, and yes, it snowed. Perfect! You don’t want to be late with this exercise, or you will miss the opportunity to intervene their journey north with a place to live and brood their young.

The birds will thank him later.

Generally, tree swallows, which normally nest in hallowed out, dead trees, of which there are fewer than ever, fly north in spring as insects come to life after a long winter. Their range is broad, from the Maritimes to BC, up to the Arctic circle. They are “socially monogamous” which means, if this needs explaining, that the mom and dad are a pair. According to Wikipedia, 8% of males are polygynous which we will leave to you to look up. 


After meeting, mating and choose a home to raise a family, the dad sticks around to help with the nest building and feeding of the young. By mid-July to early August they have trained the kids how to fly, hunt and get along before they start their long journey to their happy winter hunting grounds as far south as south America and the Caribbean Islands. 


Ben’s 5 year old son was keen to know what we were doing, pounding posts and hanging wooden boxes in the meadow. His 2 year old daughter was more interested in picking weeds and running….. forever running! Thank goodness Ben's wife Sam was there to join the fun, not just watch the kids but to help steady the nesting boxes as they were secured

In time, this family outing in late April has the potential to sprout in to a bigger adventure, where cleaning out the nesting boxes each fall, and observing which ones are successful at attracting expecting parents fills future days on the farm. 

There is, in our opinion, nothing quite like watching swallows dart and dive at remarkable speed: flying cigars or miniature torpedoes in the air! 

If you are successful in attracting swallows to your yard they will make you stop, look and listen. 

Which, given this time of year when every Canadian gardener is raring to go and not likely to stop until we are exhausted, is not a bad thing. 


Enjoy your May. And be sure to keep an ear out for the birds.

THINGS TO DO THIS MONTH

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.


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.


Get ahead of insects and disease with Dormant Spray. Wait until nighttime temperatures are above freezing for an after dark 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.


Overseed the lawn with quality lawn soil and grass seed, and apply a quality fertilizer to existing lawns. Set your lawnmower high, above 2.5 inches, for the first cut.


Prepare your containers. Containers should be emptied of last year's soil and replaced with quality stuff. The point is to replace used, tired container soil with the best new soil you can get your hands in and put last year's container soil in your garden. If you live somewhere off the ground, like a condo, give the soil to a friend who owns some real estate.


Prepare the soil. Meanwhile, back on the ground, enhance the quality of the soil in your garden with generous quantities of compost. Mark spreads two to three centimeters of compost over most of his garden this time of year. He lets the earth worms "work it in" to the sub soil.


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.


Empty your finished compost (bin), add compost or composted manure to your garden before planting.


Slow down and enjoy the bird song.


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, which is celebrating it’s 50th anniversary this year.

 

In May I will be participating in the Birds Canada Birdathon to raise funds that will help conserve and protect Canada’s birds. Once again, this year I will be birding around the prairies and badlands near my home in Drumheller Alberta. 

I have been taking part in this important fundraiser for over 20 years. All proceeds from the Birdathon help sustain essential conservation programs at 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.

If you’d like to support my fundraising efforts, you can donate at: https://www.canadahelps.org/en/charities/Birds_Canada/p2p/birdathon26/team/birds-canada-staff/member/jody-allair

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

 

Good Birding!
