I myself like to recycle potting soil into raised beds, so using perlite is out as it turns to mush and is useless after 5 years. I use other products that actually work better and last forever.
Those being pumice and diatomaceous earth. Pumice is not as good as DE which is fantastic as long as you get the right particle size. I really don't care about being organic, I use what works. I try to stay organic, but growing peach trees, one cannot. I also like some of the soluble fertilizers. I like organic too, but at times soluble is a better option. Sometimes with plants you need immediate nitrogen, calcium, or sulfur, and the soluble deliver big-time. Not organic.
