More Proof Green Tomatoes Will Ripen
I bought these green tomatoes to paint, not eat, because I liked their spidery-looking leaves and their glossy green skins.
But I had to go away on a trip, and left them sitting in my studio.
They should be ready to eat soon!
So, I'd say, don't compost all of your green tomatoes, bring some inside and let them ripen slowly.
It takes about 3 weeks.
