Warning - requires a LOT of water as it dries out very quickly in the hot summer sun.
Hung one from our deck last year - the plant got very large, but only had three tomatoes develop on it. Just about the time they were getting red, the squirrel thought they looked really good. So, he jumped from the deck ledge and clung to the vine, picked the tomato off, and sit it on the ledge for his own personal little buffet! Found the tomato on the ledge with a portion of it eaten out. Left it there for my daughter to see, and later the squirrel came back to eat some more of it. Threw that tomato away - so he picked himself another one! BTW, I know it was a squirrel because I saw him jump onto the plant at one time. Of course, I chased him away. But obviously, he came back later when there was no one around to bother him.
After that, I gave up watering the thing and threw it away.
