What's Happening?
The Morton Arboretum in Lisle, Illinois, is advising gardeners to apply a layer of mulch to protect plants during the winter months. Sharon Yiesla, a plant knowledge specialist at the Arboretum, recommends
spreading mulch evenly over the soil to insulate plant roots from extreme cold and prevent premature growth during unexpected warm spells. The mulch should be 3 to 4 inches deep for trees and shrubs, and 1 to 2 inches for perennial beds. It is important to keep mulch away from the trunks and stems to avoid rot and pest issues. Mulch also helps retain soil moisture and adds nutrients as it decomposes.
Why It's Important?
Proper mulching is crucial for plant health, especially in regions with variable winter weather. By insulating the soil, mulch helps maintain a stable temperature, preventing plants from breaking dormancy too early. This practice not only protects plants from frost damage but also supports their growth by improving soil quality over time. The advice from the Morton Arboretum is particularly valuable for gardeners looking to maintain healthy landscapes and avoid the costs associated with plant loss due to winter damage.
