PLANTING INSTRUCTIONS
Prior to planting, soak seeds in warm water overnight to reduce germination time. Work organic fertilizer or compost into the ground before implanting.
Celery seeds should always be sowed indoors first for best success rate, 8 to 10 weeks before the average last frost date in your area.
For summer gardeners, a late summer direct sowing is possible.
Harden off seedlings before transplanting by reducing water slightly, and keeping them outdoors for a couple hours at daytime.
Transplant seedlings 10 to 12 inches apart, direct sow seeds ¼ inch deep. This will necessitate to be reduced to 12 inches apart when they get to about six inches high.
