Keeping Trees & Shrubs Healthy Through the Dormant Season

By Bradley Hill, Hoppe Plant Health Care Manager and Certified Arborist WI-1235A


In late summer plants really start to show signs from insect damage, disease and weather stressors. New spring growth is long gone, and pests, pathogens, and weather have left their mark. Temperature extremes and other abiotic factors can put trees and shrubs in a vulnerable state, making them more prone to insect and disease damage. Fall is a great time to prepare plants for a long cold Wisconsin winter.

Evergreens and arborvitaes in particular are susceptible to desiccation from dry winter winds. Anti-desiccation sprays can be applied in fall that work by coating the plant to help them retain moisture through the winter. Regular watering in the fall months before the ground freezes will also help trees survive the winter with less damage. Fall fertilization can enhance overall tree health and provides micro and macro nutrients that are not as abundant in poor urban soils. Fall is also a great time to apply soil insecticides to protect trees from pests in the following growing season.

During the dormant season and while there is snow on the ground, there is less food available for animals. They can turn to your plants as a food source. Animal repellants can be applied in fall to deter animals from feeding on your plants. All of these fall services can benefit your trees and shrubs all year long.
