Ken, I grow almost all my plants in 90% pumice 10% sand/clay, no organics. My collection turned into a mushroom farm when the winter rains started in SoCal. The 40% perlite mix you mention would be too wet for my preference. My seed mix is 90% pumice 10% perlite, and I do quite well with everything from Lachenalia to Aloe to Cyphostemma to Brunsvigia.

These had been in a homemade soil mix of about 40% DG, 40% perlite, 10% local (clayish) soil and 10% home-made fine compost. I will leave out local soil and compost ... what do you think of perlite as an component with pumice? Coastal San Diego is usually relatively cool, but I should have been more aware of the hot humid weather that can occur here in late summer. > > Ken > From: Jacob Knecht <jacobknecht@gmail.com> > Subject: Re: [pbs] Oh No!
