Hi all

Decided to try them again though I've never had much success in the past. Instead of starting from seed as I had always done before, this time bought 4 plants. I planted in 4 different locations as an experiment to find out if they would perform better elsewhere. All locations get at least 6 hours of sun/day. 3 area are rather sandy soil one of which gets much more water than the others. The 4th is in a raised bed. None of them has grown quite as much as I had expected. They are all about the same size -- approx 7 inches tall. Planted them back in early to mid June. Quite disappointing. Any possible ideas as to what I'm doing wrong?
