I just planted some Bok Choy last week and it is already popping up. I want to make sure I have really nice heads and NO BUGS! Any advice out there? I did have cabbage worms on my broccoli in the spring and have had a couple of different bugs eat my squash and cantaloupe, so they may still be hanging around the garden. I did destroy all those plants after I pulled them out--didn't want to leave eggs around to hatch. I'm wondering about using some covering. I look forward to hearing any suggestions.
