Last year's tomatoes were from a neighbor who had too many, all in one tiny pot. He ended up giving me about 30 of them that I planted in three big pots. They survived up until February or so, but only made a few small tomatoes, most of which stayed green.
This year I bought a packet of seeds, rehydrated some peat pellets I had lying around, and sprouted six of them myself. Here they are, after a couple weeks in a cheap plastic incubator (clear dome cover not pictured):
I potted them last weekend. So far they're still strictly indoor plants until they get big enough to survive being dug up by roving area mammals. Then they'll get moved to my big pots from last year. I might try to find some high shelving to put them on, and let the vines grow downward instead of staking them upward. I've heard that works better.
I also have an unused 3-foot sill planter thing. I'm thinking to try putting strawberries in them. But that might have to wait until next year.
