I'm growing a plant for the first time. Planted it in
the compost heap (last years!) and it has gone
berserk. However whilst I have 3 good sized squashes
slowly ripening, many others have seemed to set, start
swelling, then go brown and rot from the flower end.
Anyone know why this is please?

Also, how do you know when they are ripe?
