In Our Gardens
Sheryl:
Well, the first frost has already happened here in Calgary and so I’ve been watching the forecast like a hawk and covering the tomatoes as required. I swear, my tomatoes have been covered nearly the whole growing season – first, to protect them against the threat of multiple hailstorms, and now this! I have already harvested a pleasantly sizeable yield of ripe and ready currant tomatoes and my husband and I have been enjoying them in salads and I’ve been taking them to work just to snack on. I’m still waiting on my precious ‘Black Krim’ tomatoes, though…they are still green and I’m waiting on a bit of a blush to happen. If you pick them when they are TOO green, they won’t ripen indoors…you have to reach that special threshold.

I have picked quite a few lovely zucchinis over the past several weeks and they’ve been cooked up in various ways in my kitchen. Did you know that you can shred zucchini, drain the excess water from it, then pack it into bags and freeze it for later use? It’s a good solution if you’re swimming in summer squash! I saw a great tip in the Alberta Gardening group on Facebook last week from a gardener who goes one step further and freezes the shredded zucchini after packing it into the cups of a muffin tin. When it’s ready, she just snaps out the iced zuke pops, bags them individually, and puts them back in the freezer. Nice and tidy and ready for that chocolate zucchini cake at a moment’s notice!
And I’ve been saving seeds…calendula, dill, nasturtiums, beans, and sweet peas so far. I can’t stress enough the importance of labelling the plants that you want to save seed from so that you can easily locate them later on when they’ve stopped blooming. This year, I just tucked in some old wooden skewers I had kicking around and fashioned a tag with a piece of coloured tape. I wrote the colour of the flowers on the tape – for example: a calendula with DBL (double flowers) with BRN CENT (brown centres). I planted several types of calendula this year and wanted to differentiate the doubles from the singles, and identify the colours. I also had several colours of nasturtiums, so I tagged them to remind myself where the red ones were in the sea of cream-coloured ones. You’ll be sure to come up with a labelling system of your own – just remember to do it in advance, as it makes seed saving much easier. I always think I am going to remember the exact location of everything but I never do….

Floral Miscellany
Sheryl:
Did you know…that hawthorn berries are not really berries at all? They are pomes. (Apples and pears are pomes, too). Hawthorn berries are commonly called “haws”; rather reminiscent of the ‘’hips” from roses. (And, in fact, hawthorns are related to both apples and roses – they’re in the same family). Right now, you’ll be seeing the bright red fruit on hawthorn trees growing on the prairies – they look a bit like tiny ornamental crabapples or indeed, like oversized rose hips. I’ve been experimenting with making jelly from hawthorn berries…stay tuned for a blog post containing the recipe!
I’m a bit late in putting this up as I filmed it two weeks ago, but here is a short plant profile on ‘Candyland Red’ currant tomatoes. They’re a bit of a novelty, but I really love the size of the fruit for use in fresh green salads – they’re perfect!
The e-book versions have been available in the catalogue for several months now, but we unpacked some boxes of new books at work last week and guess what was in one? I couldn’t resist taking a photo of them sitting in their new homes out on the floor…hopefully they circulate like crazy!
(If you want to purchase, not merely borrow, a copy of the first two books in The Guides for the Prairie Gardener series, click here for more information! They are available in bookstores all across the Prairie provinces and via online retailers).
First harvest of beans today! These are ‘Dragon Tongue’, a popular, easy-to-grow heirloom bush bean from the Netherlands. Gotta love those purple streaks – so pretty! I highly recommend this cultivar for prairie gardens and beyond.

We’ve been on a podcast!
Janet and I had the pleasure and honour of being guests on Agriculture for Life’s Know Your Food podcast, for not one, but TWO episodes! We talked about growing veggies and other edibles, encouraging children to catch the gardening bug, and the connection between the coronavirus pandemic, self-sustainability, and growing your own food…and a few other topics, besides! Go to Ag for Life’s website to listen.
Congratulations to Sherryl H. and Linda H., who each won a set of The Prairie Gardener’s Go-To for Vegetables and The Prairie Gardener’s Go-To for Pests and Diseases by participating in a contest run here on the blog earlier this month. A huge thank you to our publisher, TouchWood Editions, for supporting the contest and providing the prizes for the winners!
Out and About
Sheryl:
After being laid off for nearly four months, I am back to work at the library and, combined with my writing schedule and gardening and the need to eke out a few fun summer activities while there is still time, I’m a wee bit swamped. I have an ever-accumulating load of articles to write, questions to answer for curious (and occasionally desperate and fed up) gardeners, thunderstorms to dodge (my tomatoes have spent half of their lives covered up with sheets to prevent hailstones from destroying them), and So. Much. Weeding. The weed du jour (besides quackgrass, which is actually the bane of my existence): stinkweed (Thlapsi arvense). At least stinkweed is an annual, and it spreads via seeds instead of rhizomes (or seeds AND rhizomes – shudder). It’s easy to pull but there seems to be an incredible amount of it this year. Stinkweed has the glorious distinction that if it is allowed to set seed, one plant can produce 15,000 seeds. I’m pretty sure all of those germinated in my raised beds this year, alongside a zillion annual chickweed plants (Stellaria media), which are another story altogether.
A few articles that I wrote earlier in the year have made it to publication – check out “Harvesting Rain’’ in the Summer 2020 issue of The Gardener for Canadian Climates and “Superb Serviceberries” in Mother Earth Gardener. Both of these are available on newsstands across Canada – and in the case of Mother Earth Gardener, you can find it anywhere in the United States, as well. (You can also read the article online here!). I also went a little farther afield than usual and wrote an article called “Opossums as Pollinators in Brazil” for the April 2020 issue of 2 Million Blossoms. As you can imagine, that one was fascinating to research! This is a beautifully-produced, brand-new publication out of Arizona, dedicated to celebrating and “protecting our pollinators.” (If interested, you can order a subscription from their website).
I also had a chance to do a story about houseplants, for a change – my article “Devil’s Ivy vs. Philodendron: Which is Which?” can be found online at Farmers’ Almanac. Check it out here! And, finally, “Using Colour in the Garden” was published in the July 4, 2020 issue of the newspaper The Calgary Herald. You can read it here.
Janet:
Unlike Sheryl I have been taking a hiatus from writing and workshops since the middle of June, although my article ‘Attracting Butterflies with Annuals’ is in the Summer issue of The Gardener for Canadian Climates. It was a joy to research, write and photograph and I hope any of you that take in this magazine enjoys it too.
My Horticultural Therapy programs are all in abeyance too, except for one that is online!
So, my days have been filled with planting, sowing and weeding all the gardens that folks in the programs usually do. Plus, every so often, getting into my own garden.
One thing I haven’t had to much at all is watering, seeing as the sky has repeatedly provided ample moisture. Apparently, Alberta is experiencing La Nina like conditions in the atmosphere which have been contributing to our cooler and wetter weather lately. There is also a 50/50 chance of a full blown La Nina for this winter. Can we say cold and snowy?
I have been loving the chance to get out into the wild where the wildflowers have been stunning along with the insects and birds. Usually my days are filled in the summer months and I seldom get the chance to go out and about. If there is a silver lining to this year, it is the joy we Albertans are getting from relearning our own backyards and wild spaces!

In Our Gardens
Sheryl:
As I already mentioned, weeds are what’s happening. We have had a lot of rain and now there are weeds everywhere. I’m a bit weird in that I don’t mind weeding: I like to relax in the sun and pull and dig them up by hand. Weeding is just a really nice opportunity to turn the ol’ brain off and listen to the birds sing and the bees buzz in the garden. More importantly, it’s a way to get really up close with your plants and see what’s going on almost at soil level. Sometimes you get in a rush and you run to the garden to grab a handful of lettuce for a supper salad, or you sprinkle some water over everything before you dash out to work in the morning and you don’t really SEE what’s going on out there. You need to sit and go slow to do that. If you take a look at our pests and diseases book, you’ll notice that we talk about Integrated Pest (Plant) Management. One of the tenets of that practice is monitoring. That’s one of the things you can be doing while you weed: monitor your cultivated crops and ensure they are healthy and stress-free. If they aren’t, maybe you can see what the problem is while you’re out there weeding.
In July and August, everything is up in the garden and you’re just taking it all in, harvesting a few crops here and there and waiting on others to get larger or to produce more. We’ve been enjoying spinach, lettuce, Swiss chard, scallions, garlic scapes, kohlrabi, and various herbs – and, of course, potatoes (which are honestly the real reason I grow vegetables, LOL). And now the beans are coming along as well and the zucchini (which is seriously late for me this year).

Janet:
I have been having so much fun working in my bed at Inglewood Community Garden. It is a 10’ x 4’ bed so I have taken our Victory Garden plan (which you can see here) and used it in this bed using the square foot gardening technique to control my urge to just add a bit more into it.

It is producing magnificently with my four kale plants in full production, along with lettuce and chard galore. This year with all the rain our radishes were wonderful….mild tasting, beautiful round orbs and nary a radish maggot to be found. Soon it will be the turn of the pole beans, garlic and tomatoes as they all come into their own. And I grew the best cilantro I have ever done, with it tucked in the shadow of the tomatoes and under floating row cover the entire time. A testimony to the benefits of using this ‘gardeners’ best friend’, not to mention the value it provides as hail protection!
Best cilantro ever! (Photo by Janet Melrose)
As I love to get as much as I can from a space I have already sown more radishes where the cilantro was in the hopes that the conditions there will good enough to get a second delicious crop. While the first lettuces are being harvested using ‘crop and come again’ I have sown more seed to germinate while I munch through the first round of delicious leaves. When the garlic come out in a few weeks I have more seedlings growing in wintersowing jugs to take that space to continue the bounty!
Fantastic radishes! (Photo by Janet Melrose)

Sheryl:
A couple of the questions that keep cropping up (pun intended) on the Alberta Gardening group on Facebook concern the topic of growing onions. If you’re waiting on your onion bulbs to plump up and you know it’s going to be a few more weeks, what do you do if flowers suddenly show up? Do you cut them off? Do you leave them? And some gardeners stomp down the tops of their onions at this point in the growing season because they think it will promote fatter bulbs – is that something that should be done? (I’ve seen people recommend this for potatoes, as well). Let’s get down to the bottom of this!
Janet:
Continuing on with the Allium family, garlic (Allium sativum) is taking centre stage now. Our late and cool start to the growing season has meant that they are only now developing the distinctive curl to the scapes, but now is the time to snip those scapes back to the first set of leaves. A gourmet delight and expensive in stores, use them just as you would the cloves for your summer cuisine. They pickle and pesto perfectly too if you have too many to use fresh!
Then watch for the leaves to turn yellow and die back in the next few weeks. Once they are about one third brown harvest one to see if the bulb is big and well formed. If it is, then harvest the lot as left too long after that the quality starts to degrade. Cure for three weeks in a dry and warm spot and we have fantastic garlic for the winter months plus using the best bulbs our stock for planting come fall when the cycle begins again!
If you love growing garlic like I do check out Ron L. Engleland’s iconic book ‘Growing Great Garlic’.
I’m growing ‘Lollo Rosso’ lettuce in a container on my balcony this year – I’m very pleased with this one so far! It has resisted bolting and is a tasty and beautiful coral type for cut-and-come again harvests.
What are your favourite cultivars/types of lettuce to grow?
Someone recently sent me a question about radishes, and then I had a bit of a chuckle because the same thing she was complaining about happened to me this week: they bolted. To add insult to injury, when I pulled them, there were no beautiful globular roots, just some lovely greens and the start of a bloom. While radishes are often excitably touted as one of the easiest and quickest edible crops to grow, things do go wrong sometimes. So, let’s troubleshoot this:
About the bolting:
Heat usually is the cause. Radishes are a cool season crop and tend to freak out when the temperatures tip into summertime territory. Plant them early in the season (or late in the season, if you have that luxury) and you’ll have a better chance of success.
About the sumptuous tops and lack of bottoms:
Did you space them sufficiently apart in the container or bed? They need room for the roots to properly develop.
Did you add too much nitrogen-based fertilizer? That’s not going to produce generous roots.
Is your soil compacted? If so, you might end up with misshapen roots or none at all.
Too many cold, cloudy days. Radishes may be a cool-season crop, but they do need adequate sunlight for production.
That bolting thing. It all comes full circle…when the temperatures soar, the radishes think it’s flower and seed time and completely forget about their roots.
So, my radish problem? The seeds were sown just over two months ago, so late seeding isn’t a likely candidate. I can eliminate the compacted soil and the overabundance of fertilizer, as I know those are not the culprits. Spacing was more than adequate for the variety I planted. That leaves me blaming the weather, which – you have to admit – seems both plausible AND satisfyingly convenient. 😉

There has been a lot of walking and appreciating the fact that spring is bursting out all over the place. I’ve done plenty of writing, and editing, too, as well as volunteering for the Calgary Horticultural Society and the Master Gardeners Association of Alberta answering online gardening questions. It’s always difficult at this time of year to strike a balance between going slow to properly take in all the newness in the world and the unbelievably harried (and hurried) rush to get everything done…but this year is a bit different because I am not yet back to work at my regular job at the library.

May was unbelievably busy with workshops with experienced and new gardeners all taking part in the webinars I have been involved in facilitating.
June is a slower workshop time as we are able to be outside in our gardens, but here are a few workshops happening to launch us into summer:
June 3rd – Embrace Gardening-How to Get the Most out of Your Raised Bed Part 2
We will have spent May sowing and transplanting, and things are coming up and some may almost be ready to eat. While others should not have even gone into the soil outside yet! There’s more to edible gardening on the Prairies! To register, click here.
June 4th– 2 Gals in a Garden – Sensational Succulent Planters
Succulents are a fascinating with all the different shapes, colours, and sizes! They are perfect in a container for a hot and dry summer. To register, click here.
June 11th– Calgary Horticultural Society – Bringing Back the Bugs!
Creating a welcoming garden for all the critters that are so necessary to our world is one way; a very constructive way to contribute to the larger efforts to stem the insect crash of our times. To register, click here.
June 18th– Beyond Kale* – Taking the Edible Garden Into the Summer!
Now that our gardens are growing strongly, let’s learn what we need to do to keep them that way! To register, click here.
In Our Gardens
Sheryl:
Lots going on! The community garden which looked to be shuttered for the season has now reopened…and to my surprise, they weren’t full up, so the garden leader asked if I wanted to rent a second plot. Twist my rubber arm! This gives me plenty of space to put more seed in…which I did, with huge enthusiasm, this past week. Late in the month, I also planted the plot I acquired from the other community garden I joined – I put in potatoes, onions, and a few root veggies such as beets and rutabaga. I know I will not be able to get over there often due to the distance I have to travel, so low-maintenance selections were key. I spent hours last week digging up quackgrass in my “new-old” community garden beds and found a pleasant surprise tucked in alongside the troublesome plants: clusters of dill weed volunteers. I know some people find them annoyingly…erm…weedy, but to me, dill is a staple herb – my hubby and I love its fresh leaves in potato salad and other dishes, and I always bring some to seed to use when I make garlic dill pickles. I will allow a few of these plants to grow and produce seed, and the thinnings I removed were scrubbed and used in a meal.

In the communal beds at the “old” garden there are chives and lovage and rhubarb ready for all the plot holders…especially that lovage! It grows so fast I think you could just sit in front of it for five minutes and new leaves would pop out before your eyes. Be aware if you plant lovage that it is a perennial, that it gets to six feet tall (or over), that it has a propensity to reseed, and that you will ALWAYS have too much of it as a very little goes a long way in cooking. But it is well worth having in the garden if you love to cook – it’s one of those herbs that once you’ve tried it, you’ll wonder why you didn’t plant it sooner. Plus, you seriously don’t have to do anything to get it to grow – it’s unbelievably maintenance-free.

Janet:
I am trying out our Victory Garden plan with my bed at the Inglewood Community Garden and going whole hog with a full-on Square Foot Gardening grid to boot! We were delayed getting into the garden while rules for operating during the pandemic were being figured out, but after the long weekend we got busy. I had already prepared the bed last fall and my garlic was up so I launched right into sowing all the cool season veggies on the plan along with some kale seedlings. Our monsoon rains took us out the next week but I was back in there again this week and took a chance and sowed some pole and runner beans, though I may regret it if the soil isn’t warm enough for them to germinate quickly. No way was I going to transplant my tomatoes and cucumbers in this early as the long-range forecast is calling for the obligatory cool and rainy (maybe snow) episode the first weekend of June. Did you know that [famed championship horse jumping venue] Spruce Meadows [here in Calgary] changed the date of their first tournament [on the annual schedule] to the second weekend of June because that first weekend always was snowed/rained out? I’ll wait until June 10th for those tender transplants, thank you very much!

Lots of other gardens I am involved are getting planted too with the hope that sometime during the summer Horticultural Therapy programs can resume in some form or another and will want a garden growing strongly to greet everyone! It’s a time to try out all sorts of techniques and planting schemes not to mention a few old gardening saws to see how it all works out. For starters I am trying out a large 2 Sisters planting guild at the Between Friends Camp Bonaventure garden with lots of pumpkin plants surrounding the corn and beans to see if we can ward off the hares and deer that think that garden is a buffet planted just for them! If it works our returning gardeners should have a treat harvesting everything come September!
Floral Miscellany
Sheryl:
I recently came across an unusual piece of garden advice: apparently, to reduce the risk of seeds from squash such as zucchini from rotting in the soil before they germinate, you’re supposed to sow them with the edge of the seed slid vertically down into the soil, instead of laying the seed flat onto the soil surface. Have you ever done this? It’s not wise to direct sow squash seed into cold, wet soils, anyway – it’s better to instead wait for everything to heat up a bit. (For squash and pumpkins, you’re looking at soil temperatures of 15.5 degrees Celsius/60 degrees Fahrenheit, minimum. Waiting until the temperatures approach the mid- to high twenties is even better). If you do that, then you don’t have to worry which way is up (and more importantly, you’ll likely have better germination rates!). I’ve been asked a few times whether or not it matters how you orient seeds when planting (as far as how it influences the way seeds germinate and grow) and this article from the Laidback Gardener gives one of the best explanations I have ever read.
And, as the rhubarb is growing beautifully and thoughts turn to rhubarb pie and upside-down cake and pie again, I’ve put in my two cents’ worth about how to properly harvest the plant here:
Janet:
As always, I am interested in weather and nature wisdom. Buffalo beans (Thermopsis rhombifolia) are blooming right now. They are so named because First Nations people used their bloom time to indicate that buffalo bulls were ready for the spring hunt!
(Left to right: Lilac, Buffalo bean – Photos by Janet Melrose)
Another guide is to wait till the lilacs are in bloom before setting out tender seedlings such as cucumbers, squashes, and – dare I say it – tomatoes and eggplants. Seeing as the lilacs in Calgary are only just budding out, though I have seen a few in bloom downtown in the heat island, we had better pay heed and have the patience to wait till they are in full bloom.
Beer traps have long been used for slug control but there is another way to trap them that doesn’t involve you sharing your precious brews (because, really, why should slugs get the good stuff?). Try this very basic yeast trap instead:
Ingredients:
1 cup water
1 tsp sugar
1/2 tsp dry yeast
Instructions:
Throw everything into a jar and mix it together. (You can double or triple this recipe if you are attending Slimapalooza and require lots of bait. It’s best to mix up a fresh batch each time you need it).
Raid your recycling bin for some shallow containers and sink whatever you scrounge up into your garden bed so that the tops of the containers are level with the surface of the soil. In effect, you’re creating a drop of doom/swimming pool sort of scenario. Pour the bait mixture into the containers so that they are about 3/4 full. Then go crack that beer and enjoy the rest of your evening. Slugs come out at night so check your traps the next morning and dispose of the contents in the garbage.
What are your tried-and-true methods to combat slugs?
Sweet potatoes, perhaps; yams, no. Yams (Dioscorea alata) cannot grow on the Canadian Prairies – they are native to Asia and the Caribbean (where they are a perennial vine) and require a very long growing season to be able to produce tubers.
Under certain conditions we might be able to grow sweet potatoes (Ipomoea batatas), which are sometimes mistakenly called yams (at least in the grocery stores, where the names seem to be interchangeable). Due to our short growing season, sweet potatoes are a tricky crop to grow, as we often run out of time to produce tubers. There are short-season types available, however. Cultivars such as ‘Covington’, ‘Beauregard’, and the Canadian-bred ‘Radiance’ can produce crops in 110-120 days, and ‘Frazier White’ supposedly only needs 105 days. This is, of course, if conditions are suitable. Due to the time constraints of our growing season (for example – Calgary only has 117 frost free days on average), starting the slips (unrooted vine cuttings) indoors is essential.
Sweet potatoes also require a long period of hot, dry weather to produce decently-sized tubers, and we all know that the weather doesn’t always co-operate in that regard.
If you have the heat and the time, sweet potatoes aren’t massively demanding plants, as far as inputs go (they are susceptible to a number of pests and diseases, however). They don’t need extremely rich soil; in fact, too much nitrogen is detrimental to tuber production. Beyond watering consistently, you don’t have to do much to make this crop happy. Sweet potatoes fare best in full to part sun, and will produce sizeable vines that resemble those of another plant in the same genus: morning glories (I. purpurea).
Although things will likely change in the future as breeding efforts continue, sweet potatoes are considered a novelty veggie on the Prairies (although they are grown as specialty food crops in provinces such as Ontario). You can attempt to grow sweet potatoes in-ground or in a raised bed, but your best bet is probably to try them in containers in your greenhouse and see what you end up with – at the very least, you’ll have a lovely vining plant to enjoy all summer!
Do you grow sweet potatoes in your garden (I’d love to know – whether or not you live in Canada!). If you enjoy eating sweet potatoes, what are your favourite ways to prepare them or use them in recipes?
