Grubs

Grubs

I decided to extend my flower/garden beds by digging up the turf (well my boyfriend was kind enough to do 95% of the work). While digging we noticed grubs, enough to keep the robins in the neighborhood quite happy. I understand that grubs will wreck havoc on the grass however I am wondering what happens to any plants that will occupy that space?
