There's no denying it: the two pots I bought for the additional tomato plants aren't big enough. They were expensive, but even so they're too small.
But a smart friend suggested that two five-gallon •buckets• would be much more suitable, and Lowe's has them cheap. I'll have to make some holes in the bottom, but that's no problem.
I'm just worried that the repotting will be messy. But I'll deal with that.
