In the spring, emerging cutworms will be waiting to feast on your garden. Cut off their food supply by delaying transplanting or planting by a couple weeks if possible.
Put barriers, such as stiff paper or cardboard collars, around plant stems to help stop cutworms from reaching tender stems, especially right at transplanting.
Circle stems with diatomaceous earth or crushed eggshells.
Sprinkle used coffee grounds around your plants.
Apply an insecticide late in the afternoon for best control.
Sprinkle used coffee grounds on the infested area.
Keep up with cultivation. The moths prefer to lay eggs in high grass and weeds. At the end of the season, plow or till the garden and mow surrounding areas to expose cutworms and destroy their winter habitat.
