Finding your seedlings mysteriously toppled over or your mature plants showing signs of severe stem damage? The culprit might be lurking just beneath the soil’s surface: cutworms. How Do You Know If You Have Cutworms feasting on your precious garden? Recognizing the signs of their presence early is crucial for preventing widespread damage and protecting your plants.
Unmasking the Cutworm’s Handiwork How To Spot The Culprit
Determining if you have cutworms isn’t always straightforward, as these pests are nocturnal and spend their days hidden. However, there are several telltale signs that indicate their presence. The most obvious clue is sudden plant damage, particularly the stems of young plants being severed near the soil line. This “cut” appearance is how they earned their name. You might find seedlings completely gone, as the cutworms can drag them underground to feed. Look for these common signs:
- Toppled seedlings with cleanly cut stems
- Irregular holes in leaves, especially on lower foliage
- Wilting or stunted growth of plants
Beyond direct plant damage, examining the soil around affected plants can also reveal clues. Cutworms are typically found curled up in a C-shape just below the soil surface during the day. They are typically grayish-brown or black, and can be up to two inches long depending on the species. Check the soil by gently digging around the base of affected plants. The damage can vary based on the type of cutworm. For example, some types of cutworms feed on the roots and underground parts of the plants. The root feeders are harder to spot but often have similar symptoms:
- Plants struggling to grow despite adequate watering.
- Discolored or unhealthy-looking foliage.
- Loosening or instability of the plant in the soil.
Finally, consider the time of year and recent weather conditions. Cutworms are most active in the spring and early summer, especially after periods of rain. The ideal environment for cutworms is moist soil with plenty of plant debris for them to hide. In fact, you can set up a trap to see if you catch any. A simple example is to use a rolled-up newspaper placed near damaged plants. Check it in the morning to see if any cutworms have taken refuge inside. Or you can use a flashlight during night time to find the worms. Here are some things to consider:
| Factor | Relevance |
|---|---|
| Time of Year | Spring and Early Summer favor cutworm activity. |
| Recent Weather | Moist conditions encourage cutworm presence. |
