He's the one I got the pepper plants from last year. I still have the pots from those, but I think they'd be too small for tomatoes.

I wouldn't plant tomatoes in the same pots as last year's peppers. Your not supposed to plant peppers, tomatoes, eggplants, or potatoes in the same spot where you planted any of the above the previous year. They might get the wilts. I guess you could try sterilizing the pots with hot water or something.

They're fairly little pots, so wouldn't work for tomatoes anyway. I'm thinking of planting chives in them...that would probably be OK, no?
