This is probably a veg/greenhouse combo question...but,
I had a couple tomato plants take root in greenhouse floor and let them grow all summer to see what would happen.
A few have matured and ripened, but now there are dozens and dozens of green tomatoes all over the vines, but they don't seem to be on their way to ripening. It's plenty warm and sunny in there.
So what's the answer...they just started too late and won't ripen, will ripen with more time, or something else? Time to pull them? Let them go?
Any thoughts would be appreciated.
