Q: I have a new bermuda lawn. My lawn maintenance company wants to aerate it. Is it too late to aerate a lawn that was planted in April?

A: I think the best time to aerate bermudagrass is in May, when it starts growing rapidly. The holes you put in the soil promote oxygen exchange plus water and fertilizer penetration. Fall aeration might be helpful if the soil is really compacted but that should not be the case if the lawn was tilled before the sod was planted in April.
