My bok choi and brussel sprouts are being eaten, near as I can tell, by wasps! When the damage started, I examined the plants daily, and could never find any bugs, except there is always a few wasps on the plants. I try to stay away from them, as our wasp colony can be aggressive at times. But the other day I was watching them, and they are eating the plants! I watched the little bugger eat a hole in the leaf! I had no idea wasps did this, and these are the only plants they bother. My neighbor suggested covering the planter w netting, which I will be doing. But, has anyone else had this issue? Is this common? And how do I know which plants to cover to avoid this in the future?
