(Best months for growing Celery in USA - Zone 5a regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 54°F and 70°F. (Show °C/cm)
  • Space plants: 6 - 12 inches apart
  • Harvest in 17-18 weeks.
  • Compatible with (can grow beside): Not applicable as celery needs to be close together to encourage blanching.
  • Avoid growing close to: Sweetcorn
  • Celery seedlings

Most varieties improve with blanching but there are some self-blanching varieties available. To Blanch: plant in trenches 15- 20 cm (6-8 in) deep and 20cm (8in) apart. Leave about 40 cm (17 in) between rows. Fill the trenches gradually and keep well watered as the plants grow. The plants can be lifted to use, as needed after about 11 weeks. Alternatively wrap the plants in sleeves of paper or black plastic.

Celery needs moist fertile soil.

Culinary hints - cooking and eating Celery

Chop and use raw in salad or braised in hot dishes.

Hi, what does the word "blanching" mean in the above context: (Compatible with (can grow beside): Not applicable as celery needs to be close together to encourage blanching)? Thanks, Miroslav Andjic

If you plant celery close together the stalks are protected from the sunlight and the outside leaves are a light green/white colour - blanched. Plant them far apart and the stalks are darker green and a bitter.

Blanching celery means that a portion of the stem is white instead of green.

Thank you very much Liz.

I've never used seed for growing celery. I buy an organic/non organic bunch, chop off the base place in water and replace the water regularly and place on kitchen bench in sun for a while. Once its starts growing ( starts fast but I let it grow for a while) I then plant it. I've just pulled an amazing bunch planted undercover but northern sun that started just before the recent Sydney rain event in March. I was concerned with the flavour being watery and bland due to the soil being blanched by all the rain so left it in a bit longer when the sun came out. Amazing!!. I am now growing another one from the base of this one I just grew.

Celery is originally a riparian plant - i.e. grows naturally at the edge of streams and so on - so all the rain is their happy place.

Hello all, I agree with EC sunshine coast and Rokky, I have both seedling plants (garden centre bought) growing nicely in raised garden beds since the beginning of May (temperate climate -Adelaide, day temps range from 14 - 18 currently overnight temps 6- 10 . I started planting Celery bottoms in June from supermarket bought celery bought weekly. Both lots are growing really well. All are planted close together, to promote blanching and structure, some are stringless and some regular stringy type. Now that we are past the Solstice hopefully the longer days will encourage good growth. I treat the growing beds with Bicarb water solution for disease and sprinkle the growing beds with Blood and Bone for plant growth and to keep the local possum away.

Michael, your mention of bicarb is interesting. Would you mind sharing what proportions you use and how often? Thankyou. Teresa.

Find it strange to plant out celery in November, December when celery is best grown in winter especially flavoursome when it’s hit by the frost

I'm sub tropical Bundaberg and planted seeds in March last year. Too much chance of big rain and pests in Summer.

My celery plant has been wilting more and more. It has been raining quite a bit in the area, and I checked the dampness of the soil but the plant is still wilting more. The leaves are not yellowing but they are getting darker each day. I am unsure of how to proceed or if it will even survive. Thank you in advance.
