Why Fall Is Prime Time for Broccoli in San Diego
When it comes to growing broccoli in San Diego, fall is the perfect season. Our mild climate (USDA Zones 9–10) gives broccoli just the right balance of cooler nights and sunny days. Planting in late summer through early fall ensures that plants mature in optimal conditions—producing sweeter, crisper broccoli heads while avoiding the heat stress of summer.

Step-by-Step Guide to Broccoli Success
1. Start Strong
Direct sowing works, but starting broccoli seeds indoors in late summer gives plants a healthy head start.
2. Planting Window
Plant broccoli in San Diego between mid-August and October for the best fall harvest. Early planting leads to stronger growth before the days get shorter.
3. Preparation & Spacing
- Choose a sunny location with nutrient-rich soil.
- Space broccoli 12–20″ apart with good airflow.
- Add compost to boost soil health and structure.
4. Feeding & Watering
- Keep soil evenly moist but avoid waterlogging.
- Mulch to lock in moisture and reduce weeds.
- Fertilize at planting and again when heads start forming.
5. Watch for Pests
- Protect seedlings with row covers.
- Rotate crops annually to reduce pest buildup.
- Use organic treatments if caterpillars appear.
6. Harvest & Beyond
