To all you experienced heirloom gardeners out there, how do I know when my Green Zebra, Black Krim, and Amazon Chocolate tomatoes are done? Is it a squeeze test, like testing that steak on the grill for firmness? The greens are green. The black/purple/brown tomatoes are turning and deepening. Should they have any green left at the crown when ripe?
The Costoluto Genevese tomatoes are such eye candy, I really don't want to cut into them. Also, a plant I have labeled as "Green Zebra" now has red tomatoes- that whole dog incident we had way back when really put a hurting on my ability to keep track of the varieties....good news is one of my unmarked plants appears to be a Green Zebra...or a stripey that hasn't shown it's true colors yet. (Me rolling my eyes.)
