There are a number of different types of squash ranging in mature colour from pale green to bright yellow. Pick when you feel your squash has stopped growing rapidly. Once the flower is pollinated you will see 2 weeks or so of rapid growth, after which it slows down somewhat. Experience of your own plant will tell you when is the best time to pick them, too big and they get 'floury' and too small and they are not ripe enough. Learn from your own plant, and let them grow.

I also would like to know when to harvest squash as this is the first time I've grown it. Do you harvest it the moment the flower dies off the end inlike comment before mine are yellow on plant

when should you cut yellow ruffle squash from the plant? We were told to cut them young and green and allow to yellow, but they have not yellowed as yet.
