Broccoli

Summary

Broccoli is one of the winter vegetables that will need to be grown in media beds due to its size and weight. As a crop with a high nutrient uptake, broccoli can be hard to grow in newer systems.

Growing

Broccoli thrives in lower temperatures with an ideal temp being around 14 or 15°C. In warmer temperatures, most varieties are susceptible to bolting. If warmer conditions are unavoidable, try selecting a variety that is bolt-resistant.

Seedling are ready for transplantion once they have grown at least 4 true leaves and reach at least 15cm in height. Broccoli are highly susceptible to pests and will require additional attention in this area.

Harvesting

When the buds of the broccoli heads are firm and tight, it is time for harvest.
