Taking the time to fertilize in the fall will strengthen roots going into winter, giving plants a strong base on which to thrive next spring. Now is the last chance to fertilize before the ground freezes.
“Mycorrhizae and root hairs are abundant and active in winter. Our tree concept must be expanded to include these facts.”

- soil drenching for smaller trees and shrubs
