The Town of Coaldale handles the maintenance of trees in parks, recreation areas and along town roads throughout the year. Residents are encouraged to keep their own trees healthy in order to protect the overall health of trees throughout our community.
It’s spring and time to check your trees to ensure they are getting the proper water, nutrients and air in order to maintain their health. Ryan Moman, Town Arborist encourages residents to mulch the root zone to keep roots moist and cool. Mulching will also help inhibit weed growth.
If you are not seeing new growth on trees, visit a landscaping or nursery and pick up some tree and shrub fertilizer. Trees also need air in order to grow and won’t do well in hard compacted soil. If you’re planning to plant new trees, work in some organic matter such a peat moss or compost from your garden composter. Mix it in with the soil before planting your tree.
Local issues – One of the issues for trees in Coaldale is the spruce sawfly. If you check a spruce or evergreen, you may notice some tips of branches are bare, they are being chewed or sucked on by insects and most of the time it is the sawfly. There could be other insects so if you notice this on your trees and it is more than a couple of branches throughout the tree, call a tree care service.
Another issue for Spruce trees in Coaldale is the white pine weevil. If you look at the tips at the top of the tree, or the leader, and see no needles left and a bend to the branch, known as a shephard’s crook, you have the white pine weevil in action. It will need to be pruned out of the tree. Call a tree care service.
Elm Tree Pruning Ban – From April 1 to September 30 of every year there is a ban on the pruning of elm trees. If you have trimmed a tree please do not leave branches lying around, get rid of them but dropping them off at the local landfill. Do not use elm wood as fire wood.
Green Waste can be placed in your compost bin. Tree branches, with the exclusion of Elm wood, can be cut to 4 foot lengths, bundled with natural fibre and a set out a foot from your compost cart.

Conservationists want to keep the invasive pest out of Alberta for as long as possible, said Jon Sweeney, a forest research scientist with Natural Resources Canada.
"Once it gets to a place, about 10 years later, more than 99 per cent of the ash in that area have been killed by it," Sweeney said.
