How to grow Zucchini, step by step
Sow after frost
- Direct-sow a few seeds in warm soil; thin to the strongest plant.
- One or two plants is plenty for most families.
Feed & water
- Rich soil and even water keep it cranking.
- Mulch to hold moisture and keep fruit off the dirt.
Pick small & often
- Harvest at 6–8 in — that’s when it’s best and keeps the plant producing.
- Check daily at peak; they hide and balloon overnight.
