“plenty of fertilizer”
“catnip...nasty white moths”
“cut the broccoli off from the sides into the middle...not loose the whole plant”
In Sarasota County, Florida, I can get some broccoli, but only one small harvest as the season is short. I mainly grow tomatoes and herbs.
Squash can be productive, but it always gets attacked.
These are the things I do when growing Broccoli up here on The Frozen Tundra.
1. I agree with giving it adequate fertilizer. Anything ‘balanced’ works just fine. 10-10-10.
2. Cabbage Moths CAN be an issue. They are the small white or yellow ‘butterflies’ you’ll see flitting around any Brassica crops. They will lay their eggs there, and that’s why you sometimes get green worms in your Broccoli at harvest time. Row covers prevent this.
3. If we have a mild summer, and not too hot, I leave the plants alone after I harvest the main head, and it will produce side shoots all summer. The ‘Lieutenant’ brand has been really good for that.
4. Start seed in July and plant starts in early September for a second Fall crop. The Cabbage Moths will be gone by then, so my fall crops are usually pristine. (Worm free!)
