We have had Brussels sprouts growing in the community garden, would be better to plant them in cooler months or plant them just before the cooler months so we can harvest them. Brassicaceae same as cabbage and Broccoli, cauliflower to avoid the cabbage moth from eating the leaves? we don't like to use chemical sprays. All natural.

Seed was planted in June. When should Brussels sprouts be harvested in zone 7?
