tomato soil mix

[Ed of Somis]

i have grown tomatoes before in containers...but this year i am getting serious. On another website i have learned the importance of free draining soil mixes. I sure have noticed a difference with my custom bark/perlite/peat mix vs. Commercial potting soil/mix. The 'light' soil-less mix is producing healthier plants....hands down. Perhaps this is a coincidence....i doubt it. There are some minor variables. My commercial mix plants look stressed (rolled leaves, slower growth, etc)
