Wow Geoff! Nice job! I'm sure you are going to have a bountiful harvest. I haven't tried book choy just yet, but it's on my list. Next year, I'm going to try my luck with okra - I understand it thrives in the AZ heat. Funny thing, tho, I've tried twice with peppers (sweet and hot varieties) and they never really flourish. I'm thinking maybe peppers should be considered a perennial here? Any advise on peppers for me?
