Optimal temperature and pest control methods are key factors in protecting broccoli growth in a garden. The vegetable grows best under moderate temperatures and may require additional equipment to protect it from varying weather conditions. Being aware of the pests that feed on the plant and how to get rid of them is also essential to protecting broccoli patches.
- Broccoli does best in cool conditions with temperatures between 60 and 70 F. (15-21 C.). It can be damaged by a sudden heat wave or a sudden freeze.
- If your broccoli heads are near harvest and temperatures are expected to drop below 30, cover the plants overnight but remember to remove the coverings in the morning.
- Many insects like to dine on broccoli, and keeping broccoli safe from these pests is no joke. Even birds get in on the feast by eating the cabbageworms.
“Broccoli does best in cool conditions with temperatures between 60 and 70 F. (15-21 C.). It can be damaged by a sudden heat wave or a sudden freeze. To keep the plants from being damaged by a late or early frost, allow the transplants to acclimate (harden) gradually to the outdoor temperatures.”
