volunteer squash, winter or summer
I'm new to the site and to gardening, so please bear with me! I decided to let a volunteer squash grow out of my compost and now I can not tell when I am supposed to harvest it. It is yellow with a green circle around the bottom and turns a bit orange when left on the vine. It starts out small and kind of regular summer squash shape but then grows large and round like acorn squash. I picked a larger one (football size maybe) last night that had been on the vine for a few weeks. When we cut it open it looked a lot like acorn squash (except yellow orange) with pumpkin like seeds. The shell is relatively soft. The meat was thick and cooked up almost like potato. Very starchy. Is this a summer squash that I left on the vine too long? Or a winter squash that I should have left on the vine longer? Does this sound familiar to anyone?
Thanks for any help.
