The Handyman and I were discussing the possibilities after we noticed a very sad roma hanging from the upside-down bucket on the right.
The other two sweet 100's look great, so if the roma doesn't perk up soon, he may be transferred to the raised bed space (and replaced by my favorite, gardener's delight!)
The first year of upside-down tomatoes, the handyman did a brandywine, a juliet, and a forgotten-variety of cherry. The brandywine did okay, but it had a pretty average yield with quite a bit of weight-strain on the plant. The others were superb.
Last years patio princesses and gardener's delight and tumbling toms were all quite successful, even if the patio's didn't ripen very quickly in our cool summer.
No matter what works best, my favorite's still the gardener's delight (have I already mentioned that?). We went to Moeller's Nursery down in Corvallis - they'd advertised in Craigslist that they have twenty-something tomato varieties, all for $1.25 a piece. They definitely didn't disappoint.
They didn't have gardener's delight, but they said the cherry red's were identical (I hope they're right!) I also got some sunsugar and sweet millions to try... In the meantime, I'll poke around the old interweb to see if I can find a more definitive answer to the question!
(P.S. Moellers had bell peppers and hot peppers for a buck each. And holy moly, it was petunia heaven - even Burpee doesn't have that many varieties for sale! It was great!)
