Old Man Winter has been breathing down your neck with ice, snow, wind, and extended periods of below-freezing temperatures. You can defy the cold with warm coats, hot beverages, and fluffy slippers—your trees, however, are exposed to the elements and may need some extra care to survive.
Here are five tree care tips that you can use to help your trees thrive during the remainder of the winter season.
1. Winter watering
Many trees go dormant during winter months, but that doesn’t mean they are dead. Winter is a dry season, and many trees can get brittle and dry without additional watering.
It’s best to water your trees a few times a month, ideally when the soil is dry and the temperature is at least 40 degrees. You should water between the tree trunk and the drip line. Give your tree a good drink, but do not leave the soil soggy, as this creates a risk of root rot or suffocation. Water earlier in the day to let the water soak into the soil, which makes a protective layer of warmth during night-time freezing.
2. Insulated covering
Just like you, your tree will stay warmer if it’s given a coat. Giving your tree an insulated covering is a great way to trap warmth in the earth near the tree roots, protecting your tree from damage that comes with freezing temperatures.
For coverings, you can use burlap, old sheets, tarps, or insulated coverings you can purchase from garden centers. Make sure the covering is large enough to extend from the tree trunk to the ground to trap heat in. You’ll also want to be sure that your insulated covering is not interfering with the tree’s foliage.
Another benefit of insulating your trees is to protect them from sun scalding and the harsh winter winds that dry out and strip away the bark. Properly insulating your trees will go a long way to keep your trees healthy during winter and thriving when the growing season returns.
3. Mulching
Maintaining a nice layer of mulch around the base of your tree will protect the roots and help retain moisture and warmth. Leave a few inches of space from the tree trunk to the edge of your mulch—this discourages rodents from building nests at the base of your tree and then chewing on the bark. Winter wind and snow can erode your mulch pile, so keep some fresh mulch on hand to replenish it as needed.
4. Pruning
Pruning your trees is a vital part of tree maintenance. The ideal time for pruning is toward the end of the tree’s dormant season (November to April). You can remove any limbs damaged by the winter weather, and the lack of foliage will make it easier to determine what to prune.
By pruning during the tree’s dormancy, you make room for new growth once spring begins. If you are concerned about pruning your trees without additional information, contact a licensed arborist, who will have the expert knowledge needed to advise you on how to prune your tree based on its type, age, and the season you are pruning in.
5. Clearing and protecting
Rock salt is a classic addition to Midwest winters, and while it’s great for keeping our roads and sidewalks clear, it’s not so great for your trees. Rock salt interferes with your tree’s ability to absorb water, which can dry your tree out during an already-dry season. If you need to melt the ice near your trees, look for ice-melting products that contain calcium, potassium, or magnesium chloride, which are much safer for your plants.
The inevitable accumulation of ice and snow can damage your trees by putting extra weight on the branches, leading to snapping, tearing, or splitting—which is unsafe for you and your trees! Clearing your trees of snow and ice using careful methods such as gently shaking the limbs or hosing them with warm water (not too hot) from a hot water faucet can remove the snow and ice and leave your tree intact.
Winter is not easy, but you can make it easier on your trees by following these tips. Take care of your trees during the harsh winter, and come spring and summer, your efforts will be worth it when your trees are beautiful and thriving!
