What if it rains after I fertilize my lawn?
Does it matter if you fertilize before a heavy rain? Yes, it does. This is not a good time to apply fertilizer because a heavy rainfall could wash away the fertilizer before it has an opportunity to break down and be absorbed. The light rainfall can substitute for watering in the fertilizer after application.
What happens if you put down too much pre-emergent?

Can you put too much crabgrass preventer on your lawn?
If you apply too soon, you shorten the back end of your protection. If you apply too late, crabgrass is up and growing before you stopped it. (In rainy weather, by the way, the preventers can break down and leach into the soil even faster than 8 weeks.) One solution is to double up on the preventers.
