Gardeners' Corner at the

Calgary Horticultural Society

It's Summer!
The Society is into its summer programming. Tea with Kath will continue on Facebook Live and Garden Coaching will be online using Zoom meetings. Open Gardens tours are being recorded with formal video launch dates scheduled for July 19 and August 9. The office is still closed to drop-in visitors, but you are welcome to stop by the gardens and see what's in bloom. The deep purple of the Salvia at the front of the garden can be seen as you pass by while travelling north-bound on Macleod Trail. The native bed is in full bloom. The peonies smell wonderful. The yellow foxglove reins in the rain garden. In the back garden, the Evans cherries are turning red and the garlic scapes are curling.

Calgary has many lovely public gardens. Stop by Reader Rock Garden, the Botanical Gardens of Silver Springs, Central Memorial Park, or Lougheed House gardens. Summer seems to move swiftly, so be sure to spend some time in a garden to relax and enjoy the sights, sounds, and fragrances of summer.

Summer Staff
The Society has been able to welcome two summer staff onboard: Christopher Campbell and Leora Cohen. 

Christopher has joined the team as videographer. He is a Broadcast Media Studies student at Mount Royal University. During the last two weeks, he has been helping Nisha Sridhar with the creation of the Open Gardens videos. Going forward, he will be responsible for creating most of the videos for this summer's Open Gardens video tours.

Leora has joined the team as a horticultural specialist. She is a recent Plant Biology graduate from the University of Calgary. Under Michelle Edworthy's guidance, she is reviewing and updating material for the Master Gardener program, community gardens, gardening resources, and plant database. If you watch the Open Gardens videos posted on the website, you'll have seen Leora interviewing the gardeners.

The extra help has already made a big impact. We're excited to their see what their contributions will bring throughout the summer! 
Calgary Gardening—Roses
Often when someone says "rose" we think of that solitary, sensuous, red rose on a long stem—a tea rose. Tea roses are not hardy in Calgary, but there are many other beautiful and aromatic roses that are. Read June Bergman's article And You Thought Roses Could Not Be Grown In Calgary in the July issue of Calgary Gardening magazine to learn more. 

Visit the Members Only section of the website, log in, select the Calgary Gardening menu, and enjoy reading about gardening.

Did you know that Calgary Gardening is published eight times a year on the first of the month of August, October, December, February, April, May, June, and July?
Plant Database
The Society often receives plant information requests. Did you know that the Society has a plant database? Silvia Kallen, while a Master Gardener student, prepared profiles to add 30 plants to the database. Leora Cohen, our summer horticultural specialist, has already reviewed 14, and they are now available on the website, expanding the plant list to 124 entries. 

The listing for each plant includes a photograph; summary of characteristics such as height, spread, light requirements, bloom time, colour(s), soil needs; and uses (including whether or not it is deer- or rabbit-resistant).  

You can browse through all the plants listed alphabetically by Latin or common name, or use the search filter to find plants with specific characteristics. 

The Plant Database is a members' benefit and is available after logging in to the Members Only section of the website. Non-members can see the list of Perennial Plants of the Year, under the website's Resources tab, but to see all the plant details, you need to access the plant database.

A huge thank you to Silvia and Leora for helping us expand this member service!

The next draw will be made on July 16. Enter the contest and let us know about your water-wise gardening practices. This month's prize is a copy of the Society's garden journal and $25 of Blue Grass Bucks (vouchers that may be use at Blue Grass garden centre).

Community Gardens
Community Gardens—Leafy Veggie Challenges
The garden is producing some nice leafy greens, such as Swiss chard. However, upon closer inspection, they are developing what looks like blisters. This is an indication that they may be food for more than the gardener—there may be a leaf miner enjoying the produce.

Usually, the first indication of a leaf miner is a trail in the leaf or a blistered area. Upon closer inspection, the trail may have black specs, which are the frass of the caterpillar that is eating between the top and bottom layer of the leaf. The consumption of the mid-leaf tissue causes the blister appearance. If you look closely at the blister, especially when held up to the light, you may see the small caterpillar. If the damage is minor, you can kill the caterpillar by squishing it in the leaf tissue. Badly affected leaves should be removed and put in the garbage. 

The caterpillar is a larval stage of a fly. The fly cuts holes in the leaf to feed and then lays eggs in the feeding holes. The eggs hatch and the caterpillar eats its way into the leaf. It will eventual pupate and then become a fly. The process can take as little as two weeks. 

Manage the leaf miner problem by squishing the caterpillars, removing the damaged leaves, looking for eggs on the under side of leaves and squishing them, and spraying the leaves on both sides with water to remove overlooked eggs and the adult pests (the adults can live for two weeks). Once the problem is noticed, daily inspection is recommended. Do not compost the damaged leaves, put them in the garbage.
