The Q&A Archives: Plants Cut Off At Ground

Question: A number of my annuals have been cut off at ground level and left laying on the ground. Not eaten, no holes in the leaves. Any idea what's causing it and how to stop it?

Answer: Sounds to me as though cutworms have sheared your annuals off at ground level. These grubs encircle the plant stem and gnaw their way through. You can stop the damage by placing a twig or a toothpick about a half inch into the soil and one-quarter of an inch away from the stem of the plant. This will keep the cutworms from circling around and chewing through the stems of your plants.
