Tree work has seasons, and a surprising amount of it has to happen in a window that closes before most people start thinking about their yard. By the time the snow is gone and the first warm weekend arrives, the best windows for several jobs have already passed and every crew in the city is booked.
February is the month to plan. Here is what is time-sensitive, what has a hard legal deadline, and what can wait.
Dormant Pruning Ends at Bud Break
Most structural pruning is best done while a tree is dormant and leafless. The branch structure is fully visible, the tree is not spending stored energy on foliage, and there is less disease pressure.
That window closes when the buds break. Once a tree has leafed out you can still prune, but the tree pays more for it and the crew cannot see the structure as clearly. If you have structural work in mind, it should be booked before spring arrives, not after.
Black Knot and Disease Pruning Have Deadlines
Black knot on mayday, chokecherry, and plum has to be pruned out while dormant, before the galls start releasing spores in spring. Cut during wet spring weather and you spread the disease around the tree you are trying to save.
Fire blight strikes are removed in dry conditions or dormancy for the same reason. These are not preferences, they are the difference between treatment working and treatment making things worse.
Elms Have a Legal Window
Alberta prohibits elm pruning between April 1 and September 30 to protect against Dutch elm disease. That means any elm work has to be done by the end of March.
This one catches people out every year. An elm that needs pruning and does not get booked in time waits until October, which is a long time to live with a branch over the driveway.
Removals Are Easier While Frozen
Winter and early spring removals have practical advantages. Frozen ground carries equipment without rutting a lawn, there are no leaves to clean up, and access across a yard is often easier.
If you already know a tree is coming out, doing it in the cold season is usually cleaner and easier on the property than waiting for June.
Planting Goes on the February List Too
Bare root stock has to be planted in early spring while dormant, and the best nursery selection goes early. If your plan involves bare root trees or a shelterbelt, ordering happens in winter, not in May.
Utility locates take time to arrange, so the call goes in well before the shovel comes out. Planning the planting in February is what makes an April planting possible.
What Can Wait
Not everything is urgent. Summer deadwooding, clearance pruning over a roof, hedge trimming, and most hazard reduction work can be scheduled any time the crew can get to it.
Knowing which jobs are time-critical and which are not is what keeps a yard on track without paying for rush work. Aardvark Tree Care books spring work across Calgary through the winter, and a quick walk around the yard in February is usually all it takes to know what belongs on the list.
Elm work has to be finished by March 31; after that the law says it waits until October.
