Underplanting sweetcorn with celery.

I sowed the first lot of seed, and nothing happened. So I put a second lot in,.............................................and all of them came up. Maybe it's a bit typical of this season.
So I have a shedfull of celery...............and no room on the plot.

How? If I plant one celery with sweetcorn will it grow better than 100?

[/quote]My point was that you didn't mention having a glut of celery and having nothing to lose by planting them where you said.

And yes, one celery with sweetcorn would have much more chance than 100.

What variety of celery is it Andy ?

It is  No 22188 Full White self blanching from The Real Seed Catalogue.

I obviously need to find somewhere else to plant it but have run out of space.
I may just put it outside my plot in tray's for others to enjoy.

Thanks for the input. 

Thanks for that. Aunt Sally. 

Nothing should really be planted under sweetcorm in my opinion as the competition is detrimental to their growth.

You can plant squashes outside of the sweetcorn block and allow them to run between the plants.  They act like a mulch then.
