If you have plants that suddenly keel over in the middle of the night, you might have cutworms. Closer inspection will usually reveal that the main stem has been severed from the roots.The adult cutworms are night-flying moths that lay eggs on grass tips or on the soil next to lawn or plant stems in the fall.
