I bought a water melon plant and a gala melon plant from B&Q a few months back. I have planted them in two separate tyres (some thing I found on the website that I have now lost) in a green house with a string for them to climb.
Their on a water irrigation system at the moment and get watered twice a day for ten minuets. There both about 4 foot tall now and they are starting to flower. What should I do now???? Where do they fruit from?

Yours hopefully a truly novice gardener
