What Would Be Cutting Just the Clematis Off

Question

The last two years I have been watching my clematis being cut off at the ground level. They do not eat the plant, they just get cut off. I am not able to find anything. They do not eat my morning glories. Help please. I don’t know what to do.

Answer 1

If the damage is on new growth at or near the soil line, it could be cutworms, which normally feed at night (their daylight counterparts are called loopers). During the day they hide in the soil or leaf litter below. Treat the plants with neem oil and this should help.
