To my knowledge worms that feed on corn do not hatch out until corn is ready to feed on. I think you have slugs. A product called Sluggo used according to the package directions should do the job. Cut off the yellow leaves of the violas, They may be pouting. Best And Happy Yardening, Nancy.
Ageratum Leaves Have Holes And Viola Blooms And Leaves Are Yellow
Question From: A. Middleton - INDIANA
Q: I just planted four ageratum's in my front yard as well as a few viola's (planted and in hanging pots) last week. Temperatures, sunlight and rain/watering have been appropriate levels. This morning I noticed holes in the leaves of all the ageratum and I have several yellowed blooms and leaves of the violas. I looked it up and it sounds like it may be a corn earworm. Does this sound correct and how to fight it? I read that the corn earworm will also munch on corn, summer and winter squash and tomatoes...all of which I will have in my garden very soon. Help!!
