no, I suppose not...... really wanted to let my tomatoes ripen on the vine. We've been told so often that they Can't ripen on the vine, unless they're cherry tomatoes, that I want to prove "them" wrong! I've had one ripen on the vine and it was soooo tasty! I have several that I think will also ripen.... going to check them this afternoon (they're in my garden at a friend's yard...)
