Cutworms hide during the day in the soil near the plants, then feed on plant stems at night. Their damage is most severe right away in spring when plant stems are more tender but not a problem later in the summer. Unfortunately, it's too late to manage cutworms any longer this year. That cutworms were very common this year does not necessarily mean that they will be numerous next spring. There are too many factors that influence cutworm numbers to make a prediction now for 2011. Regardless of how numerous they will be next spring, if you have had an issue with them this year, be on the watch for them in 2011. For more information, see Cutworms in Home Gardens.
