The three melons seem to have stopped growing now, and one only reached kiwi-fruit size. This one I discovered sitting in a wet patch and was beginning to rot on the end, so I have had to pick it. It felt ripe, although there was no aroma, but obviously we had to cut the rotten bit off and therefore had to stick a spoon in and taste it. It's juicy, but doesn't have much flavour. I will stop watering them now so hopefully the other two will be a bit sweeter when they ripen.
