Celery is a vegetable where the entire plant is edible: root, stalks and leaves.
Core celery facts

Family – Apiaceae (parsley family)
Type – vegetable, biennial

Celery is the ultimate fall and winter vegetable. Here are the tips on how to grow it.
There are 2 major celery families: stalk celery, where the ribs are eaten, and celery root, also called celeriac, where only the root is eaten.
Stalk celery can itself be divided into two sub-families, green stalk celery and golden stalk celery.
Planting celery seedlings
Planting celery from purchased seedlings is the easiest and most efficient manner of growing celery.
Celery seedlings are planted directly in the ground from mid-April to beginning of June, depending on the climate (wait for the end of the stronger frost spells).
- Amend the soil or mix compost into your soil when planting.
- Choose a rather sunny location.
- Space your stalk celery seedlings 12 inches (30 cm) apart along a row, with each row 14 inches (35 cm) from the next.
- For celeriac or celery root, space seedlings 16 inches (40 cm) apart along a row, and space rows 16 inches (40 cm) from each other.
Sowing stalk celery
In spring, sow in a greenhouse or cold frame and transplant directly to the ground 2 months later.
Transplanting them from the sprouting bed to a nursery pot in the meantime will help the plant develop more before planting.
For these ribbed celery plants, it is important to tie the leaves together, to blanch them.
- Sowing must be done in very light soil, with sand and only thinly covered.
- Celery requires rich soil that must be amended beforehand.
- Transplant as soon as your celery has grown 2 or 3 leaves.
Sowing celery root or celeriac
Sowing can start a bit earlier, as soon as February in mild climates.
Just as for stalk celery, proceed to prepare seedlings. But when you are transplanting them into the final growing bed, snip off the tip of the main root.
Avoid planting celery in the same spot for the following 4 years, so that the soil may recover.
Caring for celery
Growing celery from seed to harvest requires little care and the plant can be used in a great many culinary combinations.
Celery is very demanding on the soil’s organic nutrients. It will help a lot if you enrich the soil with vegetable fertilizer during the growing season, and add soil conditioner or compost before planting.
Run the hoe along the ground regularly and water in case of high temperatures and prolonged dry spells in summer.
- Water regularly, especially in hot weather, because water needs are high.
- If celery lacks water, it will be prone to bolting and going to seed.
Harvesting stalk celery
Before harvesting, you must blanch your celery.
- Ridge the soil up around your celery stalks to force the leaves together.
- Pile dirt up to ¾ the height of the leaves.
- It is also possible to run a piece of opaque plastic around your celery to block out the light.
As for pulling the plants out, cut the leaves as low as possible at the end of summer.
You can dry these leaves and use them as an herb or spice.
Harvesting celery root, celeriac
- It is best to pull them out before the first frost spells.
