insects eating roots of petunias
I planted some very healthy supertunias a few days ago. They had been doing great and then this morning, they were laying over-seemed like they had been cut and were not attached to roots. Digging into the soil, I saw no roots where the plant was! Is this an insect that eats roots? What pesticide is best, and can my plants be salvaged? Will they re-root? The actual leaves and blooms were not bothered.
Petunias are usually pest free for the most part; however aphids and cutworms occasionally affect these plants. In this case, it sounds like cutworms may be the culprit, as they typically 'cut' the plants as you describe.
