its to do with exluding the light thats why you blanch them by earthing them up ,some folks wrap news paper/cardboard around them

That and the fact that celery is naturally a bog plant, so they can never have enough water. Anywhere swampy on your plot is where they'll be happiest.

and plenty of manure dug into the bottom of the trench a couple of weeks before you plant them out

So damp ground & sow in blocks for a bit of shade/dark ... should be easy in this weather

Thanks

thanks everyone a few interesting tips....  

I dont think I planted the seeds (in cells) deep enough, when repotting do I plant upto the first true leaves?

Well my celery plants should be very happy at the moment- they are sitting in a big puddle!
