It has been in the 90's here in zone 5 and my broccoli under row covers looks terrible, yellow and deformed looking heads.
Should I pull it out or wait for side shoots. I have really babied this crop and am disappointed. I only have 3 raised beds and I've given it a lot of my precious space !!! Thanks for help.
First off, I've grown some broccoli before. My understanding is that it is a fall-winter veggie, that performs best in cool temps. I grew a (2nd) bumper crop last season, in daily temps ranging from the mid-60s down to the high 30s. They grew best in a range from about 45-42°. We only experienced a short sustained dip (4 days?) with temps into the high 30s, and they were fine. I grow in Houston, Texas.
When did you start your plants, and what were your temps then? You're in the 90s now which is much too warm for most broccoli plants. I believe you're about to go into your fall season, yes? If so, NOW would be the time to start some seeds or get some new plants. Fill me in on when you got started, and give me a picture of what kind of weather you have ahead for Zone 5. I'm a Zone 9a grower.
