Answer: Brussels sprouts take a long time to grow and need cool weather. You may have planted yours too late. The best time to grow Brussels sprouts in Florida is during the winter, and they should be planted in October. When spring temperatures become too high, sprouts will not be produced. Some years are better than others for growing brussels sprouts and I'm afraid that this year your plants ran out of time to develop sprouts.
Two varieties suggested for for Florida gardeners are `Jade Cross,' a hybrid variety that matures in about 85 days, and `Long Island Improved,' an open pollinated variety that takes a few days longer.
