Using drain pipe over celery and leeks

I use it for leeks but not sure for celery because you need to check them over for slugs.
They can also be used for growing carrots and parsnips.

Ok thanks guys anything else they could be used for?

If not I'll keep a load and dish them out to my neighbouring lotters!!

When you use them for leeks you should always have at least a third of the plant sticking out of the top. Either start with an 8 inch pipe and then replace it with a taller one as the plant grows, or just stick an extension on with duck tape.

I did this for the first time last year to see what happend. The leeks were sown directly in the ground and I picked out a dozen at transplanting size which were piped. The rest were transplanted in the traditional dibber way. I was amazed at how much faster the piped ones grew. Who says that the growth of leeks is not checked when they are transplanted?

You could always cut them in half lengthways and use them for sowing peas, like people do with guttering?

or you could stick them in the ground next to courgettes and squashes etc and use them to direct water straight to the roots.

Thanks guys some good suggestions there too
