My 2 Atlantic Giants have now taken over my allotment. They've each got about four 'arms' some 20 or so feet long, leaves the size of rhubarb, and dozens of apple sized pumpkins........only none of the pumpkins seem to be coming to anything (I'm assuming coz they're not being fertilised?). So they shrivvle and die after a week or so. Time's marching on....WHY AREN'T THEY BEING FERTILISED? I've tried doing it manually, but the 'male' flowers don't seem to last more than a day before drying up so they're never much good. It's an organic plot surrounded by fields etc so there are plenty of insects and stuff. >:(
