Celery is one of the most challenging vegetables to grow — it needs consistent moisture, cool temperatures, and a long season. But homegrown celery is far more flavorful than anything from a store.
Good companions: tomatoes, beans, brassicas, leeks
Avoid planting near: corn, parsnips (compete aggressively for similar nutrients)
85-120 days from transplant; harvest entire plant or outer stalks as needed
