Often the turfgrass will outgrow the grub feeding damage if water stress can be avoided. It's time to start thinking about your lawn for next year. Renovation takes a lot of time and effort in the short term, but its well worth it in the long run. The first step is to choose the grass type. In my opinion, there are two excellent choices for lawns throughout most of Indiana.
Kentucky bluegrass is the preferred grass for most homelawns in Indiana.
It is a dark green, fairly disease tolerant, and performs well under high or low maintenance. Kentucky bluegrass will deliver the highest quality lawn, especially when it is irrigated occasionally. If you prefer never to irrigate, turf-type tall fescue is the best grass because it is extremely drought tolerant and will stay green even during summers like this. It tends to be a little wider-bladed than Kentucky bluegrass and a little lighter green, but these qualities are generally not greatly noticeable. Avoid perennial ryegrass in lawns because it is susceptible to many diseases.
