July's turbulent storm season keeping Calgary gardeners on guard

Early July is an exciting timefor Stampede goers, but for Calgary's gardening community, it can be aperiod that arriveswith atleast a littlewariness despite warm temperatures.

Known in some green-thumb circles as "plant hell week," thistime of year can mean some trepidation because, afterweeks of hard work and growth, gardens can facesome nastystorms and hail.

"Predictably, we get the biggest thunderstorms, lightning and hail during Stampede week, and it actually goes all across Alberta at various points in July," said Kath Smyth, ahorticulturist with the Calgary Horticultural Society.

Smyth, who begangardening with her grandfather as a child, has been an horticulturist for almost 50 years. Usually, she can predict the direction the hail is coming from, but this has changed in recent years.

"My succulents took a beating the second day after I put them out last year. The hail came from the wrong direction and I wasn't fast enough," she said.

Susan Johnson lives innorthwest Calgary. A few years ago, a hailstorm tore through her garden.

"It damaged everything. It just wiped out my entire vegetable garden," said Johnson.

Many gardeners know this frustration in Calgary.

According to Justin Shelley, a meteorologist with Environmentand Climate Change Canada, the city typically experiences a number of thunderstorms in July, just as it has so far this season.

"Especially from a gardening standpoint, those heavy downpours and that hail and winds can definitely damage plants like that,"Shelley said.

"This is typically when we see more of this thunderstorm activity occur."

Alberta has a hail suppression system that reduces the size of hail. However, Calgary's weather conditions are unpredictable.

"We can get hailstorms coming up out of nowhere you don't get a lot of notice," Johnsonsaid.

There are several ways to protect gardens from hail, according to Johnson and Smyth.

Some gardeners place tarps or garden netting over their plants. In extreme cases, household objects like pots and plastic containers are pretty handy.

As an experiencedgardener, Smyth has several semi-permanent systems in place to protect her garden.

"I have what I callmy hail suppression devices, which are essentially dollar store umbrellas," she said.

She also uses garden netting and has a succulent and cacti collection planted in front of other plants to "protect them because the rain and the hail comes straight off the leaves."

Some gardeners, like Johnson, use permanent structures, such as the one she put up after the hail damage to her garden.

"I decided no, I have to do something," she said.

"So then we put up that car shed frame and spent about $200 on buying some greenhouse grade poly and putting it over that frame and that really protects [the garden]."

Johnson said permanent and semi-permanent structures are best for Calgary's unpredictable weather.

"I think if you're a serious, particularly vegetable gardener, then you really need to have something that is semi-permanent, and we take the poly off of that frame in the winter and store it away so that it lasts a lot longer," she said.

Other remedies include planting native plants that are acclimated to this region and asking a professional for help.

Smyth advises new gardeners to be aware of the positioning of their yard.

"You want to put things so that you put them in the good exposures. Read your plant labels, talk to the garden centre folks. They really know their stuff," she said.
