  • 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 12°C and 21°C. (Show °F/in)
  • Space plants: 15 - 30 cm 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 20 cm (8 in) 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.

Could you please show me what you mean in planting and how to rap. My aunt used milk cartons but i was around four yrs old then. My job was to hand her the carton. Thank you.

Put something up the side of the plants to stop the sunlight turning the outside leaves green and bitter. You could google it.

I have been growing celery for a few years. I always blanch the Celery for about 2 weeks using a piece of downpipe. When I harvest the Celery it looks terrific. Store it in the crisper in a plastic bag with a paper towel. After about 2 weeks it turns all mushy. Any ideas what I am doing wrong?. Thanks in advance. Pete.

Make sure it is dry and put in the plastic bag. Maybe put a few small holes in the bag and use a tie.If it goes limp stand in some water for a few hours.

Celery is a good companion with cauliflower if planted together in February they are both heavy feeders

Maybe leave until March to plant out in the garden. 34 degreees here today and the last 2 days. Heavy rain can be a problem this time of year. Had 3.5

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.

Yes, you can tell how fresh your produce you buy from supermarket is. We also regrow onion, lettuce, broccoli and cauliflower. We put onion in water until roots regrow then into ground, same with lettuce, we put broccoli and cauliflower in ground and started growing before winter and then the rats decided they were hungry so didn't get to grow a head of replanted stem.
