Most years I grow a variety of tomatoes, with varying degrees of success.
I hesitated to plant tomatoes this year for two reasons: deer around our new home, and multiple summer vacations. But next year, I plan to try a tomato or two using the upside down method, maybe even making the hangers myself. I found this "how-to" on the Atlanta Journal-Constitution's site, AJC.com.
Make your own upside-down tomato system
A bucket with a securely fitting lid and handle, at least 5 gallons;
metal chain, 4 to 5 feet long
2 coffee filters or two 5-inch-square fabric swatches
Metal loop or strong wire
Hybrid tomato seedlings, preferably a cherry or other small variety
1. Cut or drill 2-inch holes in the center of the lid and bucket bottom.
2. Cover the hole in the bucket bottom with a coffee filter or fabric swatch.
3. Fill bucket with lightweight potting soil.
4. Lay coffee filter or fabric swatch over the soil, aligning its placement with the hole in the lid.
5. Secure the lid and turn the bucket upside down.
6. Cut a slit through the coffee filter or fabric
7. Remove lower leaves from seedling and plant deeply.
8. Place the bucket in a sunny location, keeping it well watered and fed with slow-release fertilizer.
9. When the plant is 1 foot tall, run a chain through the bucket handle.
10. Hook both ends of the chain to a metal loop or heavy wire.
11. Suspend upside down from a well-anchored plant stand.
