Are there any stains weeping from the bark of deciduous trees either in the trunk or from large branches? Large poplars can show dark stains where internal fluids have oozed out of a crack or small hole in the bark. Poplars are relatively short-lived trees compared to elms, oaks, ashes and basswoods. Poplars may become infected with a fungal disease that opens up the bark by killing living cells that lie just under the bark in a region referred to as the cambium. These openings are referred to as cankers. Are there many dead branches and weeping cankers in older coniferous evergreen trees such as spruce and pine? Lower dead branches are common in these trees as they age. They should be pruned off at the trunk. Upper dead branches interspersed with living branches may be a serious ...
Having said that, I do want to stress there are many benefits of having healthy vegetation of all kinds on one's property. Trees provide beauty and many functional purposes around our homes. Shade and wind protection are very obvious benefits. Well-placed trees can save energy costs associated with air-conditioning and heating. Deciduous shade trees on the south and west sides of the home provide cooling through shade during the heat of summer. Coniferous evergreen trees on the northwest and north sides of the homes in our area can reduce the force of cold winds, making the house more comfortable in the winter, thereby lowering heating costs. Urban trees and shrubs provide places for birds, small mammals and desirable insects such as bees, butterflies, dragonflies and others, with food ...
There's a menu of items for cankerworms, and those are the first ones they go after and defoliate," he said. "But they have been known to go after other deciduous trees after that. "This is more of a nuisance for people," he said. "It's OK -- it's nature working. The trees, as long as they are healthy, are able to withstand a defoliation." Does anything eat cankerworms? Birds love the little guys. "They're a nice little delicacy," said city entomologist [Taz Stuart].

I have written about the problems of spruce trees for many years. No other tree in urban Manitoba suffers more problems than these spruce trees. Reasonable looking trees can be treated but not cured of their most serious disease problem, white blister (or Cytospora) fungal cankers. The treatments will slow down the spread of the disease and give the tree a healthier appearance. It takes at least four years for most spruce trees to show some positive effects of treatment, but badly infected trees might take longer or they might simply get worse. This disease must be treated in conjunction with the other problems most spruce trees have especially spruce spider mites and tip blight (Sirococcus) disease. I do not give out the treatment program in a newspaper column because it depends on the...
