Everything You Need To Know About Growing Celery

Category:

Celery is a cool-weather crop that is native to the Mediterranean area.

PLANTING CELERY

Celery is best grown in well-drained soil with full sun and a soil pH range of 5.8 through 6.8.

They can be sown straight into the soil after the last frost or started 8 to 10 weeks before the last frost indoors using a cardboard seed starting tray.

When transplanting the seedlings that are started early, it is best to wait until they have at least 3 sets of mature leaves with a healthy root system.

They are best planted in rows that are about 2 feet apart, about 1 foot apart in the row, and about one-eighth of an inch deep.

FERTILIZING AND WATERING

To avoid any possible issues of over-fertilizing your celery, you should test your soil before adding any fertilizers.

Celery is best fertilized every two weeks with a balanced granular fertilizer such as 4-4-8, or a homemade liquid fertilizer.

They prefer soil that is consistently moist but not soaked and they will require about 1 to 2 inches of water per week.

HARVESTING

Celery is ready for harvest when the first leaf is about 6 inches above the base of the plant.

Harvesting can be done by removing the outer stalks with a sterilized pair of gardening shears or a gardening knife.

This will allow the inner stalks to continue to grow.

Another option is to harvest the whole plant by removing it from the ground and cutting away the roots from the plant.

Harvesting Celery

After harvesting, they should be rinsed, allowed to dry, and they will last in the refrigerator for about 4 weeks.

PROPAGATING

Celery is propagated through seed, therefore some plants should be allowed to go to seed for the following season.
