17.2 Planting Methods
Celery has the highest yields and develops top quality under moderately cool temperatures (55° to 75°F), good soil moisture, and relatively high humidity. The usual planting period is May 1 through June 30. Transplants are grown in greenhouses or imported from Florida. For those transplants in soil, see Chapter 9 Transplant Production. Night temperatures must be kept above 55°F to lessen the danger of bolting, particularly when plants are to be used for early planting. From 30,000 to 45,000 plants are set per acre; an ounce of seed yields about 15,000 transplants.
Maintain a pH of 6.0 to 6.5. See Table 17.1 (below) for the recommended rates of nitrogen, phosphorus, and potassium.
Magnesium deficiency may cause yellowing of certain varieties on organic soils. Apply ten to 15 pounds of Epsom salts in 100 gallons of water per acre and spray at ten to 14 day intervals. Epsom salts can be added safely to most fungicide sprays. Soil applications are not effective.
Blackheart may be caused by low calcium levels in plants, drought, or high soil potassium. Directed sprays of calcium chloride or calcium nitrate (five to ten pounds per 100 gallons of water per acre) every seven to ten days are effective. Boron deficiency causes cracked stems or cat scratches on petioles.
Boron deficiency is most common on alkaline mucks and with certain varieties. Apply 2 1/2 pounds of boron per acre in fertilizer where the problem exists. In an emergency, spray 1/4 pound of boron per 100 gallons of water per acre.

Under satisfactory growing conditions, celery reaches marketable size 85 to 100 days from transplanting. Although special blanching practices can improve color and eating quality, they are seldom used today. The crop is usually cut by hand, and larger growers often do the washing, grading, and packing in the field using large portable equipment. Celery should be cooled quickly to temperatures below 45°F by hydrocooling, vacuum cooling, icing, or other means of refrigeration and can be held a few weeks or more if storage is near 32°F with high humidity. A yield of 1,000 or more 60 pound crates per acre is good.
