Mature magnolias are total rockstars when it comes to durability—they’re naturally resistant to most pests and diseases, and they handle the cold like pros. This is especially true for the hardy varieties you’ll find at most local garden centers. That said, if you’ve got a youngster in the ground, you’ll need to give it a little extra TLC during the winter months.
Skip the Pruning Shears!
One of the most important things to remember is that magnolias aren’t like your typical shrubs; they really don’t want a fall haircut. Taking the pruning shears to them in autumn usually just ends up deforming the natural shape of the tree and, even worse, you’ll likely cut off next spring’s blooms before they even have a chance to open.
Protecting Your Young Trees
Young magnolias haven’t quite built up the “muscle” to withstand deep freezes on their own yet. To help them get through the winter, give the root zone some extra love with a thick layer of bark mulch. For the upper part of the plant, wrapping it in some breathable garden fleece or burlap is a great way to shield it from harsh winds and frost.
To sum up your winter magnolia game plan:
- Skip the pruning, and for young plants:
- Apply a good layer of bark mulch
- Use garden fleece for extra protection
