When to Plant Broccoli in Hawaii
In Hawaii, broccoli can be planted year-round due to its warm climate. However, for the best results, it is recommended to plant transplants outdoors during the cooler months from September to February. This will help in avoiding the heat stress that can occur during the summer months.
Transplanting Broccoli Seedlings
Transplant broccoli seedlings outdoors 2 to 3 weeks before the last expected frost. Space the seedlings 18-24 inches apart in rows with at least 36 inches between rows to ensure proper air circulation and growth.
General Care and Maintenance
Watering
- Provide consistent and deep watering, aiming for at least 1 inch of water per week, especially during dry periods. Hawaii’s tropical conditions can lead to rapid soil moisture loss.
- Water at the base of plants to avoid leaf wetness, which helps prevent fungal diseases common in humid environments.
Fertilizing
- Apply a balanced fertilizer rich in nitrogen at planting time and when the plants are actively growing to support robust leaf development.
Pest and Disease Management
- Regularly monitor for pests like aphids, cabbage loopers, and whiteflies, which can thrive in Hawaii’s climate. Early detection is key to managing infestations.
- Consider using organic pest control methods and crop rotation to maintain healthy broccoli plants and reduce the risk of disease.
Harvesting
- Harvest broccoli when the flower heads are firm and tight, typically 70 to 100 days after planting. Cut the head off with a sharp knife, leaving a few inches of the stem attached.
The importance of good soil
Before starting to grow it is important to take a step back and find the condition of the soil in your garden,The optimal soil is a blend that includes the mineral-rich dirt along with organicrich organic matter that plants need to thrive.
In my garden I try to compost as mutch as possible, so I can mix in the nutrient ritch compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”..
If you dont have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.
