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.

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

finally I have a garden after 33 years in an apartment! I am trying sooooo hard to grow something in my long awaiting garden but the lettuce hasn't made it, the rocket hasn't made it and I can kind of see a pin head broccoli shooting through. But I don't even know what 'plant in' or 'plant out' means? My 2 year old granddaughter planted a garlic clove in with the broccoli and lettuce and hers shooted up but mine of course was a no show, she even planted them upside down, here help please, did I start too big?
