See my potting mix recipe at
http://www.rossde.com/garden/garden_potting_mix.html. The
necessary texture -- drainage, aeration, moisture availability --
is provided by the sand and peat. You only need a little compost
(real, not some commercial potting mix) to provide the friendly
soil bacteria that release the nutrients.
