I had been wondering if I should/could stake my baby watermelons, rather than have the vines laying all over the garden, and I found this solution.
I specifically bought the kind of cucumber that said bush so I wouldn’t have to worry about staking. But my cucumber bushes are sending out tendrils. So I thought I better give them something to cling too and I have put up some short privet hedge trimmings. Nothing very tall. I hope they don’t need much.
