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.

I am doing the same....it's amazing. I have 3 going at different stages of root growth. I'm at the point to plant them out. THIS worries me. What area of garden should I plant them?

Germinating celery seed, growing from seed this autumn. Soaked the seed overnight and then spread on damp paper towel and place in seed raising mix, covering very lightly with the mix. Result, I used the entire packet of seed and I think they all germinated. 4 weeks on I have 36 of the strongest seedlings growing on in pots.

Hi Beverley, I want to try your method, & I’ve never grown celery before. A question please, do you leave the paper towel there or do you remove it at some stage ? Many thanks, Graeme

Thanks for that idea. I'm trying this year. Planted into 6 cell tray, way too thick. I'm going to try and separate them this afternoon into bigger pots. Will try your way next time.

How do I know when celery is ready to harvest

450 mm exposed out of the ground will do. And don't use it until the plants are about 300 mm tall - then they will search for the sun above.
