Celery Bulb ALBIN

Apium graveolens var. Rapaceum

Celery originates from the Mediterranean. It is grown in three forms - celeriac for thickened roots, stalk celery for thickened leaf stalks, or as a leaf form for a rich leaf rosette.

This biennial plant comes from the Apiaceae family. The fruits, like the entire plant, contain many aromatic substances. Celery is a source of vitamins, especially vitamin C (the leaf form contains up to 10× more vitamin C than bulbs), as well as B1, B2 and a wide range of minerals. Its strong aroma and taste come from essential oils.

In the kitchen, it is used for both cold and hot dishes, suitable for salads and soups. Many people are bothered by its essential oils and they cause allergies - legislation therefore lists it as an allergenic plant.

We consume stalk celery raw, in salads, or we can nibble it with meat. It provides the most benefit to our body in the form of juice for breakfast. Leaf celery is used to make salads, the stalks are consumed cooked, and raw juice is pressed from it.

How to Grow Celery

• Celery likes sunny locations, while it grows poorly in shade, is not aromatic and can be more easily attacked by fungal diseases. It needs sufficient watering throughout its growth period. Watering is important during planting and in the second half of the vegetation period when the bulb is growing. Celeriac needs to be regularly hoed.

• The long vegetation period can be shortened by pre-cultivation. Seedlings do not need to be grown in a heated room. A greenhouse or conservatory is suitable for pre-cultivation until planting time. February or March sowing applies to celeriac, leaf and stalk celery. We do not plant celery earlier than mid-May in its final location.

  Celeriac requires pre-cultivation of seedlings under glass. The ideal time for planting is early May, at the latest mid-June.

  For stalk celery, we sow seeds in a greenhouse or hotbed. Planting is done in May in beds, at a spacing of 30×30 cm. During growth, we hill up the stalks with soil so they blanch.

  We sow leaf celery in February in a greenhouse or hotbed and plant out in May.

  Seeds germinate in two to three weeks at temperatures between fifteen and twenty degrees.

• It is demanding in nutrients and calcium content in the soil. It requires clayey, humus-rich soils. Leaf and stalk celery need more sandy-loam soil. The optimal pH is 6.5 – 7.5.

• During the vegetation period, we fertilize with multi-component fertilizer. Fertilizer for root vegetables is suitable.

• Among pests, celery is mainly attacked by carrot fly and celery fly. We treat celery with Basudin (carrot fly) and Sumithion Super (celery fly) preparations.

  Septoria leaf spot of celery appears on celery leaf blades, where small gray-brown spots with a yellow margin and a large number of very small black dots form. The centers of the spots later turn brown and dry out.

  Scab of celery bulbs are brown spots that enlarge. Affected tissue becomes corky and cracks. This is followed by decay of the bulb. We prevent the disease by not growing celery on the same plot for at least 3 years. Partial protection is the use of borax at a rate of about 20g per 10m².

  Celery leaf spot appears on older leaves as yellowish, later yellow-brown spots. Leaves dry out and die. We perform preventive protection with Kuprikol.

• Smaller celery bulbs can be harvested in July. We harvest celery leaves by thinning, so that sufficient leaf area remains.

  Leaf celery begins to be harvested gradually from July and only at the end of September do we perform a one-time harvest.
