By way of a change this year we planted a Patisson Squash. Fortunately we only planted one as this plant is huge, we think it may take over the world! The problem is that on the little ticket thing which came with it it says to harvest in Oct/Nov, but we now have loads of these huge white squashes with a rather attractive scalloped edge all round, should we leave them on the plant to grow even bigger or are they edible now? Also when they are harvested how are they cooked, and can they be stored?
