Milorganite after pre-emergent?
How long should I wait to add to lawn, 1-2-3 weeks?
I put down some spring fertilizer with crabgrass preventer last Saturday, 10 days ago. I want to add some Milorganite to the lawn, but do not want to overdue the nitrogen. How long do you think I should wait before applying. We are supposed to get some rain on Thursday and this coming weekend and was hoping to add it before then if all possible.
