BroccoliFeeding
- Seedlings
- Balanced liquid fertilizer (e.g., 5-5-5) at half strength once true leaves appear.
- Growing
- Balanced liquid fertilizer (e.g., 5-5-5) every 2-4 weeks.
- Flowering and fruiting
- High potassium/phosphorus fertilizer (e.g., 5-10-10 or 2-3-1) to promote fruiting.
- How often
- At planting, then 2 times during the season. Side-dress at first fruit set and again about a month later; too much nitrogen early delays fruit set.
- Note
- Avoid high nitrogen post-flowering to prevent leafy growth at expense of fruit.
