This is what I have to play with, 20ft long, much tidier now that this, which was after the clear out. The staging on the left is 50% clear, like to do better but my boat gear has to go somewhere.

This year, I'm doing long red peppers, plumb and Italian beef toms, I suspect I will have room for a couple of extra plants of some kind but dont know what. Melons might be possible . . . but tying up in slings? not so sure. Last year I got one melon to set, did not realise I needed to pollinate by hand. I laid the plant on the soil and put the fruit on a cardboard square. It grew to the size of a grapefruit, stopped and the plant rotted at the base, we eat the melon in a fruit salad, it was superb

So, did I water it to much or incorrectly to make it rot? or have I got to do the climbing and hammock bit. I know I must pollinate with a male flower.
Or, any other suggestions . . . but not cucumbers
