I bought 5 Dill's Atlantic Giant Pumpkin seedlings in a charity sale at work.
I looked after them indoors for a while and then moved them to the green house to harden off.
Once there was no danger of frost I planted them out and then pretty much left them to it.
By the end of the summer I had quite a crop.
One for the doorstep.
