Potted evergreens can be slipped out of their pots and planted in the ground for the winter.

Wintering trees and shrubs grown in containers

Try these ideas and maybe you won’t have to purchase new plants next year

My wife and I went on a garden tour in Winnipeg this past summer and we saw just how popular the practice of growing trees and shrubs in containers has become — many of them grown as standards. Such plants are not inexpensive, particularly when many of the standards had woven stems and were quite

Fire blight-infected raspberry cane tips.

Fire blight can infect raspberries

There is no cure for this bacterial disease and pruning is the best treatment

Fire blight is a bacterial disease caused by the pathogen Erwinia amylovora that attacks many trees and shrubs (apple, pear, cotoneaster and mountain ash are four of the most common targets). The disease usually appears in late spring or early summer when it attacks the blossoms and very young growth at the tips of the

National Tree Project Planting Day held in RMBR

Project highlighted the important role that trees play in the environment

The Riding Mountain UNESCO World Biosphere Reserve (RMBR) held a “National Tree Project Planting Day” last month to highlight the invaluable role that trees play in our environment. The initiative stems from a collaboration between the Canadian Biosphere Reserves Association and the Government of Canada, which will see 100,000 trees planted in 14 Canadian biosphere

The U.S. Midwest has been fighting emerald ash borer for years. Seen here is a residential street in Toledo, Ohio. Both photos were taken in the summer. The first is from 2006 when emerald ash borer was first discovered, the second shows the near-total devastation the pest caused by 2009.

LAID WASTE: emerald ash borer a looming threat

A concerted effort will be necessary to preserve ash trees that shelter homes and fields

A village council in Manitoba’s Interlake thinks it’s a good idea to prevent an invasive insect from destroying local trees. Dunnottar just doesn’t know what it would do if emerald ash borer (EAB) chews its way into town. “We’ve sort of been aware of it,” said Village of Dunnottar Mayor Rick Gamble. “But we’re not

Edward Simpson, lead supervisor with parks in Dauphin and Dauphin city councillor, Patti Eilers sign up their community for signage about containing the spread of emerald ash borer. They were among about 65 municipal officials attending a meeting in Portage la Prairie in March to discuss ways to contain the invasive insect and pursue other community-based tree-care strategies.

Tall timber: Rural communities rally around threatened trees

The spectre of tree-destroying insects like emerald ash borer spreading in rural Manitoba underscores the urgency to begin to see trees as ‘green infrastructure’ and key community assets, say workshop speakers

Allan Derhak doesn’t want to think what his hometown would look like stripped of trees. Neepawa is renowned for its beauty and in large part because its residential streets are lined with mature elm, cottonwood and green ash trees. But Derhak, a public works employee in Neepawa, knows many of those trees’ days may be



The city of Morden sees its public trees along streets and green spaces as a valuable asset and has recently unveiled plans to reduce its vulnerability to emerald ash borer.

Morden prepares to battle the bug

The city has just unveiled its 10-year strategy to manage for emerald ash borer’s imminent arrival here. Morden officials will speak at a workshop next month on what actions other rural communities can take

Morden isn’t waiting until it discovers the emerald ash borer (EAB) in its midst to take action to protect its public trees. Starting later this winter the city will begin systematically removing the tree species that would otherwise attract the invasive beetle. One hundred and fifty green ash trees will be taken down in 2018

Protecting plants from winter damage

You’ll be glad you did when you see healthy plants come back in the spring

Late October/early November is the ideal time to plan on how you are going to protect vulnerable plants from our severe winter. The first step has hopefully already been taken where you have chosen most of your plants that are hardy to your climate zone. Many gardeners, however, like to try a few “challenging” plants


Researchers zero in on Dutch elm disease genes

Study compares resistance and susceptibility of trees and may provide helpful info for cloning tolerant ones

A new study by University of Guelph biologists has brought researchers closer to the goal of restoring American elms resistant to Dutch elm disease (DED) in cities and forests across Canada and the United States. The paper published in Nature Scientific Reports offers a closer look at specific genes that allow elms to resist the most destructive shade

Five hundred miles of trees — so far

The Stanley Soil Management Association has stood the test of time 
and continues the work it was set up in 1984 to do

When the soil began to blow south of Winkler this spring, Richard Warkentin knew his phone would ring. It did, almost on cue, as he drove the back roads eyeing dust storms swirling on a mid-April afternoon. “It was a guy wanting to plant trees,” says the long-serving technician and project manager with the Stanley
