Tips & Best Practices
- Start celery indoors 10–12 weeks before the last frost — it grows very slowly.
- Celery needs consistent moisture and rich soil. It is a heavy feeder.
- Transplant 1–2 weeks before the last frost; celery tolerates light frosts.
- Blanch stalks by wrapping with paper or hilling soil around the base for milder flavor.
