I've grown cucamleons this year for the first time. In fact I'd go so far as to say that I'd never heard of them before I read James Wongs Home-grown Revolution back in the spring.
They've received a bit of bad press from some people, but all I can say is my wife and kids love them!
The spindly vine grows like crazy and each plant has loads of these little melons on at any one time. They seem pretty trouble free, I've been treating them the same as my cucumbers, they live in the greenhouse, get watered every night and fed with home-made tomato food every third night. Lots of tasty little veg for the girls to snack on when they're "helping" daddy in the garden!
Anyone else tried them yet?
