It’s officially spring, so it's time to plant

Venture into the garden

Nepeta racemosa, Walker?s Low Catmint, is a great host plant for pollinators, as these swallowtail butterflies prove.

Spring has sprung, finally.

Wow, was it just me or does this past winter seem to have been the longest ever?

Perhaps slipping on the ice at a neighbour’s on Friday the 13th and breaking my ankle in two places and the subsequent six weeks in a cast and on crutches didn’t improve my attitude, but this last winter seemed interminable.

After my period of immobility, it was a great pleasure to volunteer at the recent Seedy Sunday organized by the Okanagan Master Gardeners and to reconnect with gardeners and vendors alike after the long years of COVID-induced hiatus.

The Okanagan Xeriscape Association had a booth at the event with volunteers spreading the message of water conservation so that collectively we will have more water available with which to grow our own food.

Upwards of 900 people came through the door at the Parkinson Recreation Centre, all eager to purchase seeds and to talk about plants, edible and ornamental, and the collective mood was one of anticipation, joy and hope.

While all those purchased tomato, pepper, and basil seeds will have to wait for warmer temperatures, there are lots of what are known as “cool season” crops that can be planted now when we are still seeing nightly freezing temperatures. In fact, they perform best in the cooler temperatures of spring and fall.

Cool season crops include leafy greens—think lettuces, spinach, mizuna, Swiss chard, arugula, and mustard greens. With the current price for a head of lettuce hovering around the $6 mark, why not consider growing your own?

Also happy in cool weather are crops harvested for their roots, such as radishes, onions, leeks, carrots, beets and potatoes.

The genus Brassica, commonly known as the cabbage and mustard family, performs best at cooler temperatures and includes broccoli, cabbage, cauliflower, kale, Brussels sprouts and turnips.

In addition to all of these edibles there are tons of ornamentals which benefit from a period of cold known as stratification, often mimicked by placing your seeds in the freezer for a few weeks.

Many of these ornamentals are also xeriscape plants so the benefits of including them in your landscapes are two-fold.

Achillea millefolium, known commonly as Yarrow, is an Okanagan native which has many cultivars—all of which are extremely appealing to a wide variety of pollinators.

The umbrel shape of the flower head makes for an easy buffet for them.

Joining Achillea, among others, are Siberian iris, multiple sedums, monarda, baptisia, and nepeta, all of which benefit from a cool start. When combined in your landscape they offer a strong showing of colourful flowers and support for pollinators throughout the season.

We are in the process of determining dates for the next xeriscape class, so check our website frequently for the latest information, at www.okanaganxeriscape.org.

Join OXA before the end of March and you will be eligible to win one of two $25 gift certificates to be used at our annual spring plant sale being held on May 6th from 10 a.m to 2 p.m. at Wild Bloom Nursery, 840 Old Vernon Rd.

Rest your lawnmower and let the lawn grow

Benefits of longer grass

Egan Davis talked to Okanagan landscape professionals recently in Kelowna at an Okanagan Xeriscape Association workshop about the "Long Grass Movement" in passive turf areas. He suggests you give the lawnmower a break.

This spring, give your lawn mower a break.

You’ve got a valid excuse not to mow the lawn. There are lots of ecological benefits to letting turf grass grow long instead of shearing it short, including the fact it provides both food and habitat for beneficial insects such as bees, birds, snakes and other urban wildlife.

In passive turf areas, the concept of allowing the grass to grow long and co-exist with flowering plants provides support for pollinators such as bees as well as providing additional carbon storage in the ecosystem.

Whether you take the long step into creating a meadow, or just reduce the amount of mowing you do is up to you.

Also dubbed “No Mow May,” the conservation initiative was one discussed by Egan Davis during his presentation to the recent Xeriscape for Professionals workshop held in Kelowna by the Okanagan Xeriscape Association.

“No Mow May” encourages homeowners to leave their grass and wildflowers long during the month of May. The initiative originated in Britain by the organization Plantlife, but has recently begun to gain traction worldwide.

Founded in 1989, Plantlife is an international conservation charity dedicated to conserving wild plants in their natural habitat and educating people about their benefits and beauty.

By keeping your mower in the shed for the month of May you are providing vital habitat and resources for bees and other emerging pollinators.

Multiple studies have shown that areas left un-mowed can contain double the population of broadleaf species and yield three times the nectar sugar of mowed areas. With the worldwide decline in pollinator populations this research gives us legitimate permission to leave our lawns long for the month of May.

Appleton, Wisconsin was the first U.S. town to adopt “No Mow May” in 2020.

Lawrence University did a study on the lawns of Appleton and found five times the number of bees and three times more bee species snacking on the un-mowed lawns.

Egan Davis is currently the parks operations manager for the City of Richmond and acknowledged the push-back from residents toward his “No Mow May” approach to turf management. But, he is emphatic that education is the key to changing people’s perception towards long grass and a less-manicured esthetic.

Echoing Egan’s sentiments is Chris Szymberski with Seed and Sparrow Landscape Design of Kelowna, who supports climate resilient landscapes. He says these landscapes can use significantly less resources and management energy.

At the workshop, Chris shared slides of a client’s project that bore witness to the transformation from a traditional turf grass, water-thirsty and high-maintenance landscape, to a stunningly-beautiful natural space which allowed the aging clients to stay in their family home without feeling overwhelmed with maintenance challenges.

If you would like to see this design concept in-person, visit the pollinator garden located behind the Laurel Packinghouse on Ellis Street in Kelowna.

Jennifer Miles from the City of Kelowna discussed the many benefits of trees in urban areas, from slope stabilization to shade. One big benefit is that their shade helps decrease energy use in air conditioning during the hot Okanagan summer months.

She discussed the primary drivers of tree loss: development, safety, and pests, and how the city is implementing new bylaws aimed at root protection for mature trees on development sites.

It was a pleasure to hear from all of the presenters at the workshop and I came away from the day with a renewed sense of optimism that we can make positive changes in our approach to environmental issues.

Fight the impacts of climate change on your garden

Gardens and climate change

The past eight years were the warmest on record—proof, if needed, that climate change is here.

That was just one fact brought to the table by Mario Lanthier, owner of Crop Health Advising and Research, at a recent workshop on xeriscape for professionals, held in Kelowna by the Okanagan Xeriscape Association.

He brought graphics illustrating the warming trend and discussed the challenges facing their lives as plants struggle to cope with increased temperatures, and the importance of providing our plants with the best start in life in our landscapes. That means we must begin by amending the soil in planting areas with water-retaining organic matter and installing efficient irrigation, since plants—even xeric ones—need adequate water to get their root systems established in the first year or two of their growth.

Lanthier recently returned from professional conferences in Europe and talked about tree species which are better able to thrive in our warming future. I was not surprised to find that two of them are already planted in our xeriscape demonstration garden, as promising species in our arid climate.

Syringa reticulata, commonly known as Ivory Silk Japanese Tree Lilac, and Koelreuteria paniculata, Golden-Rain Tree, have been growing successfully in the UnH20 xeriscape demonstration garden in Kelowna since 2010.

Joan Byrne, owner of Wild Bloom Nursery and OXA President, talked about her favourite new perennial cultivars for xeriscape landscapes. Penstemon pinifolius, Salvia nemorosa ‘Sky Blue Marvel’, Panicum virgatum, and Cotinus coggygria ‘Velveteeny’ were among her selections.

All of the above can all be viewed in one of our two demonstration gardens, in Kelowna and West Kelowna, and many others she discussed will be available for purchase at our annual spring plant sale.

Josh Smith, manager of Xeriscape Endemic Nursery, gave a presentation on the beauty of native Okanagan plants and their uses to help with erosion control. He talked about the many ingenious ways plants survive periods of drought and discussed how he uses natives as the most successful approach in stabilizing slopes on the many challenging properties rising up from the valley bottom.

New advances in irrigation aimed at water conservation was the topic of SiteOne Irrigation, as the company is keen to educate homeowners and professionals alike about the many new technologies aimed at decreasing water consumption on your landscape.

In my next column, I’ll tell you about Egan Davis’s presentation of the long grass movement in passive turf areas.

Spring is just around the corner and I can’t wait. Two of my favourite indicators of the beginning of the growing season are the opening day of The Greenery on Feb. 25, a pilgrimage for more than 20 years, and the Master Gardener’s Seedy Sunday on March 12, where the OXA will have a table. Come visit us with your xeriscape questions at Parkinson Recreation Centre. Seedy Sunday will run from 10 a.m. to 3 p.m.

Join the move towards good landscape choices

Better landscape choices

Photo: Contributed

Landscape professionals from up and down the Okanagan met last week in Kelowna to learn more and be inspired about xeriscape from the Okanagan Xeriscape Association.

We have to move away from inappropriate landscape choices such as turf grass, cedar hedges and inappropriate plant selections and instead move toward choices that better mimic our stunning natural Okanagan environment and support our pollinators, birds, and small mammals.

We humans have to relinquish our control issues and let nature do what she does best—heal herself, with our support.

That was brought home to me recently during a day-long, sold-out workshop for professionals in the landscape and nursery industries, organized last week by the Okanagan Xeriscape Association in Kelowna. Participants came from up and down our valley, while the keynote speaker, Egan Davis, travelled from Vancouver to present.

Both of OXA’s co-founders, Gwen Steele and Lisa Masini, were in attendance, as were many OXA board members and volunteers. There were municipal workers, golf course managers, irrigation specialists, nursery personnel, Master Gardeners, tree advocates, landscape designers, and many landscape companies also in attendance.

Of course, organizing a conference like that is a time-consuming challenge and I am very grateful to all of our volunteers who put in countless hours of work to pull off the extremely successful event. Thank you all.

Personally, I was pleasantly surprised to see so many young people in attendance, interested in becoming leaders in their field and being educated about the challenges that face this industry as our climate changes.

While all the presenters approached the issues of climate change and sustainable landscapes through a slightly different lens, many of the discussions on the day overlapped and built upon each other as the day continued. Through the day, I witnessed friendships rekindled and new connections being established.

On a personal level, I was able to spend time with Steele, one of the founders of OXA and my mentor, and was able to hear how happy she was with all of our work to further the organization. Everyone in that room owed a debt of gratitude for her vision.

At days’ end, a master gardener approached me and said with unmitigated glee that she had found her “tribe.” I couldn’t have agreed with her more. There was an infectious enthusiasm that permeated everyone in that room and a feeling that we had all found our tribe.

I have attended countless climate conferences over the decades but have never come away with such a feeling of that precious emotion—hope, hope for education that leads to better collective choices for our home, Earth. My faith in humanity is intact.

Give yourself that feeling by joining us. Become a member of the Okanagan Xeriscape Association by visiting our website at www.okanaganxeriscape.org. Membership costs $25 for individuals and $40 for households and includes many benefits, all of which are outlined on our website.
