So you got dormant stock this spring and you aren’t sure what to do to ensure it is ready for our cold Canadian winters?
In the fall, the nutrients and energy produced by the leaves begins to push back into the roots for winter storage. This is what will help put the tree into dormancy and keep the tree alive until spring.
Trees:
Perennials
NOTE: Cutting back perennials is mostly for aesthetic purposes. There are many insects that need this habitat to hibernate through winter, so if you choose to leave them, wait until late spring to prune once the bugs have left.
Perennials with soft foliage like hostas, or peonies: Cut back in the fall leaving a few inches above the soil to prevent excess moisture come spring.
Woody perennials: Cut back in late spring.
Primal cane raspberries: Cut back the entire plant to a few inches below the ground in early spring.
Hydrangeas: Cut back in fall.
Hops: Cut back the entire plant to a few inches below the ground in fall.
Clematis, or roses: Cut back in early spring.
Ornamental grasses: Require a large snow load to successfully stay in dormancy. (Karl Forester- cut back, Fescue/bluestem-do not cut back)
Reminder! Our warranty does not cover overwintering. It is important to make sure your plant is prepared and heathy before winter!
