- Shirley F1 broccoli prefers well-drained, fertile soil with a pH between 6.0 and 7.0. Incorporate compost or well-rotted manure into the soil before planting.
- The plants require full sun, receiving at least 6-8 hours of direct sunlight daily. Water consistently, keeping the soil evenly moist but not waterlogged.
- Apply a balanced fertilizer at planting and side-dress with a nitrogen-rich fertilizer during the growing season to support vigorous growth and head formation.
- Monitor for common pests such as aphids, cabbage worms, and flea beetles. Use organic pesticides, row covers, and crop rotation to manage pests and diseases. Handpick larger pests and encourage beneficial insects to keep pest populations under control.
Storage
- Store Shirley F1 broccoli seeds in a cool, dry place. Use airtight containers to protect from moisture and pests. Properly stored seeds can remain viable for up to five years.
- Harvest broccoli heads when they are firm and tight, just before the flowers begin to open. Cut the heads from the stem, leaving a few inches of the stem attached. Store fresh heads in the refrigerator for up to a week. Place them in a plastic bag or container to retain moisture.
- Broccoli can be frozen for long-term storage. To freeze, blanch the heads in boiling water for 3-4 minutes, then transfer to an ice bath before drying and packaging them for the freezer. Frozen broccoli can be stored for up to a year.
