What Animal Is Eating The Leaves To The Ground In Approximately 2 Hours On My Horseradish?

Question

Just seems to short a period of time for bugs to eat the leaves to ground just little nubs of leaves left.

Answer 1

This sounds like the cabbageworm, which will feed on plants in the genus, Brassica. There are several ways to control them, my favorite being Bacillius thuringiensis (Bt). It is a non-toxic microbe that is quite effective. This article will give some more suggestions:
