I put cabbage and Brussel sprouts under the netting last year-not a single cabbage moth or looper in there (well, not until late in the season when one must have gotten in when I harvested some cabbage or weeded). So, it worked well!@Acre4Me - got the rutabaga covered!
I was thinking I could maybe try broccoli & cauli next year under cover then y'all talked about squishing bugs on that cabbage & I changed my mind.
