How to — and how not to — care for your trees during an Iowa winter

(Radio Iowa) – Today (Thursday) marks the arrival of winter, and soon enough, we’ll be dealing with big piles of snow. Aaron Steil, a consumer horticulture specialist at the Iowa State University Extension, says the drought has been tough on our landscaping this year, and some recent plantings, trees and shrubs may already be stressing as the colder weather settles in. Steil says it’s normal for some shrubs to turn brown or orange at this time of the year.
“Eastern red cedar, for example, tends to get kind of a brownish color in the winter, but it’s more dark green during the summer,” Steil says. “It’s been a pretty stressful growing season. Most of the state has been on the dry side this year and the last couple of years, and so it’s starting to build up, especially on younger or less established plants in our landscape.” Homeowners may be concerned about their trees and other plants being damaged by a heavy, wet snow, especially if their limbs are sagging.
“Most of the time, plants do a pretty good job of shedding that snow off all on their own,” Steil says, “but if you do have a younger plant, or an evergreen that seems to be very weighed down by snow, you can go out and brush it off using your hand or a broom.” If you want to clear that snow off yourself, he says there is a right way — and a wrong way — to go about the process.
“Just make sure you do it in an upward motion instead of a downward one,” he says, “so that you don’t stress branches that are bending down even more.” Steil says ice can do infinitely more damage to young plants than snow, however, he says you need to resist the urge to try to remove ice from their frozen boughs and limbs.
“You’re likely to do more damage than good. If you try to go out and remove ice from shrubs and trees in your landscape, you can go out and maybe prop something up with a board, if you’re really worried about it,” Steil says. “Otherwise, trying to break it off or throwing hot water on it to try to melt it off, all of those always do more damage than help.”
The best thing you can do for an ice-coated tree, he says, is to leave it alone and let the sun warm it up.
