Although celery poses a challenge for home gardeners, the resulting harvest of versatile, delicious vegetables is worth every effort.
Celery does best in cool weather and especially enjoys cool nights. Grow celery in spring in the North, planting transplants two to three weeks before the average date of last frost; in the South plant in the late summer.
Celery prefers rich soil high in organic matter that is well able to hold moisture but with good drainage. It does well in wet locations. Celery is a heavy feeder and needs plenty of fertilizer for quick growth. If you're sowing seeds for transplants, start them two to four months before your estimated planting date: They germinate slowly. Transplant them to trenches 3 to 4 inches deep and two feet apart. Space the seedlings 8 to 10 inches apart.
Celery will be bitter if it isn't blanched. Blanching is achieved by covering the plants to protect them from the sun. As the plants grow, pile soil up around them to blanch the stems. Having the plants fairly close together will also help blanching.
The time from planting transplants to harvest is 100 to 130 days. Start harvesting before the first hard frost, when the head is about 2 to 3 inches in diameter at the base. Cut off the head at or slightly below soil level.
