Tomatoes with Trees

These tomatoes were planted by my neighbor and are hanging on the Black walnut tree downfield from the cottage. He seems a little disappointed in their performance, but I assured him that they look great regardless.

Personally, I think he’s skimping on the water - these plants aren't close to the houses, so they don't receive as much attention. Has anyone else had experience growing tomatoes from hanging buckets? It’s always seemed like such a great space saver, but I have yet to try it myself!
