As promised earlier, grub damage is now becoming apparent on lawns that are greening up with the recent rains. Grub damaged turf will not green-up with the rest of the lawn and is likely brown for good (dead) (see accompanying photo). Unfortunately, there’s not much you can do now and insecticides are certainly not effective now. . Your best bet is to fertilize these areas with the rest of the lawn, trying to encourage the few living grass plants to spread. Then dormant seed these areas in November or December (see accompanying Turf Tip on late fall seeding options). Rake the dead areas to expose the soil and then sprinkle Kentucky bluegrass over the areas. Be sure to water these areas as needed next spring and summer, and avoid herbicides on these areas next spring.
