Several plots at the Moreau Community Garden have been visited by cutworms.
If you see a ring of yellow paper around your tomato plant, it was put there last night by fellow gardeners in an effort to keep cutworms from destroying your plants. If the cutworms already ate one of your plants, we replaced the dead tomato plant with another tomato plant we had on hand.
What are cutworms?
They are the caterpillars of night-flying moths. They are called cutworms because as they feed on stems and can cut down young seedlings of a variety of vegetables including bean, cabbage, carrot, celery, pea, pepper, potato, and tomato.
What do they look like?
Cutworms vary in color and can be brown, tan, green or gray and black. If you touch one, it will curl up. It is important to clear weeds from your plots and surrounding pathways as this is where the adult moths lay their eggs. The emerging caterpillars (cutworms) feed on the foliage or small roots of weeds or crops.
What can I do?
Most cutworm damage happens when the plants are small. Check you garden plot. If you can be there in the evening this is ideal as that is when they are most active. Sometimes, you can find the culprit in the morning if you run your hand over the soil near the chewed plant. They don’t travel far. Handpick them and get rid of them.
Pulling weeds helps eliminate egg-laying sites and the food source young larvae need to survive.
Another control is to make collars for the seedlings. The cardboard, aluminum foil, or paper barrier keep cutworms off the plants. Some gardeners recycle toilet paper rolls and paper towel rolls for this purpose. Cut the rolls in three inch long sections and place around the stem, burying one end in the soil.
If you find cutworms in your plots, get on top of the problem swiftly as they can do a lot of damage in a short amount of time.
