I tried this idea last year and had great success. I had lots of eggplants but bugs and worms kept attacking them. So I purchased cheap knee high panty hose from Wal-Mart for less than $.50 per pair. They come in a little plastic type egg. It was well worth the purchase to save my veggies.
I have 3 watermelons growing right now and want to keep them protected so I have covered them with the knee highs. Can’t wait to see how they do.
