About Celery

Celery is made up of stalks with leaves on top that are arranged like a cone and attached at a common base. It can reach a height of 18 to 24 inches. The stalks taste delicate but somewhat salty, and they have a crisp texture. It is a biennial vegetable that is a member of the Umbelliferae family, which also includes parsley, dill, fennel, carrots, and parsley. Although celery is most commonly associated with its esteemed stalks, it also has leaves and roots that can be used in food preparation, flavoring, and as a natural remedy.

How to Grow Celery Indoors?

1

Soil Preparation

Celery grows best in fertile, sandy, well-drained soils that are rich in organic matter.  Celery needs a lot of nutrients in the soil because it has a tiny root system and is a poor nutrient forager. Before planting, add a complete fertilizer (16-16-8) to the soil. To prepare the soil for planting, work the compost and fertilizer into the pot to a depth of 6 to 8 inches.

Planting and Spacing

Usually, celery is transplanted. Before transplanting, transplants should have 3–4 mature leaves and an established root system. Seed can be sown directly in the container in regions with particularly lengthy growing seasons, and it can then be transplanted at the right spacing later.

Celery is sown from seed around February 1st, and depending on your region, it is then transplanted to the final container in late April or early May. Plants should be placed 12 inches apart. A compact planting encourages tall growth and long petioles.

3

Watering and fertilization

When you grow celery indoors, successful celery cultivation depends on proper watering. During the growing season, celery requires at least 1 to 2 inches of water. Celery has a short, shallow root system, so always water the soil properly. Any water stress during the year makes the stalks stringy and imparts a bitter flavor to them. If celery is routinely irrigated, especially before harvesting, it will be crispier and more tender. Celery responds to supplemental fertilizer in addition to the fertilizer applied at planting to provide the best yields.

Managing Pests and diseases

When you grow celery indoors, you may encounter the following plant problems:

  • Powdery Mildew: Older leaves begin to develop white fungal patches before dying. All plant parts eventually become infected with the illness. Plant resilient cultivars. Apply the proper fungicides for control and water the plants during the day so the leaves can dry.
  • Black Heart: In the middle of the plant area, the leaves show black discoloration, eventually resulting in the death of the tissues. An injury develops gradually and becomes apparent later in the season. This nutritional imbalance is caused by a localized calcium deficiency, which is crucial for cell growth. Apply calcium-rich fertilizers to the soil to control the black heart. Use calcium sprays, bone meals, or blood meals. A simple method to reduce this issue is to avoid water stress.

5

Harvest And Storage

When celery stalks are a foot or longer, harvest them by removing the outer petioles. When a plant is 3 inches in diameter or more, it is complete and ready for use. The tenderest and best-tasting stalks are those near the center. Celery that has been gathered during a hot, dry spell may be hard, stringy, and bitter. For up to two weeks, keep celery that has been harvested in the fridge.
