Planting & Care

Celery should be started indoors, with soil temperatures between 70 F and 75 F
Celery is difficult to germinate. It doesn't tolerate heat and a stretch of cold temperatures after transplanting outdoors can cause the plants to bolt (flower and form seed)
Harden plants off by reducing water, not lowering exposed temperatures
Space transplants 6 to 12 inches apart in rows spaced 18 to 36 inches apart
Set out in the garden 2 weeks before the last expected frost date
Use a floating row cover to moderated soil and air temperatures around the plants and protect plants from insects
Mulch soil around plants to retain soil moisture and suppress weeds
Do not let plants dry out as they become bitter and fibrous

Problems

Aphids, cabbage loopers, cutworms, whiteflies, tarnished plant bug
