When To Fertilize Grass And Trees After Long Winter

Question From: MICHIGAN
Q: We in Detroit are having a long winter season. How does this affect my timing for things like fertilizer for grass and trees? And what about treating my trees with Imidacloprid for leaf hopper. This has to be in the tree's system well before the first leaves come out. Last year I was done with these thing weeks ago. Thanks


Bob, You can treat your trees now but wait on the grass fertilizer. Do it now and you will be wasting your money. Best to fertilize when the grass is up and growing. Dormant grass won't take up any nutrients. Best And Happy Yardening, Nancy.
