14" and 16" pots and they could have been larger, each holds a tomato or a pepper plant plus one herb, usually the squirrels leave the basil alone, so to keep them away I added a little basil plant to each pot. I keep it cut back and so far it's working.
I felt the same way about making another bed.
For the first month or so I thought I wasn't going to have to stake the tomatoes, but then we had a massive wind/hard rain storm for about an hour the other day, and though I didn't lose either one of the plants, they were really beaten down. So now they are staked and are looking fine. I do have to keep them watered in this heat.
