Hi there it will be my first spring/summer on my allotment.  The site is prone to flooding (I'm ok) but the land is generally damp and then obviously gets worse when it rains. 

With this in mind what will grow ok?

celery was originally a marsh plant, leeks will tolerate some wet. Is it wet enough for rice??

Not many plants can cope with really waterlogged soil - take your cue from what those around you have done and are growing (if they have put in extra drainage and/or created raised beds of some description you may have to consider doing likewise.)

I find sweet peppers appreciate damp soil, and celery definitely loves it.

If you're worried your soil is too boggy, them build up mounds that you plant into. This way the roots have a drier area and if they need moisture, they can spread into the lower damper areas. Rather like raised beds.

try building up the soil on your plot with old manure.but this take time.

WEEDS - they grow OK everywhere 

Rule of thumb

If it dies dispite all your TLC then its a plant
If it grows without any TLC then it's a weed

More instant results come from digging in sharp grit with your manure.

Celery might be a good idea to try.

And celeriac, if well fed.

Celeriac grew quite well in mine last year and brassicas.

Oh so true

My peas are weeds?!

Try ridging the soil. About 4in high ridges should be ok. Makes weeding a lot easier too.
