What makes fertilizing trees and shrubs any different than fertilizing any other plants?
In our climate, all plants are either herbaceous or woody. Woody plants have parts (such as trunks, branches, twigs, or evergreen needles or leaves) that live over from season to season. That gives them a big head start each year. Herbaceous plants do not have that advantage. They start from the soil line in spring and die back to the ground in fall. That means they have to expend a tremendous amount of energy during the growing season to produce all those stems and leaves and to help them out, we need to make sure they have the fertilizer they need.
