Tropical garden soil
Concerning the soil type preferred by the Pygmy date palm, and other tropicals to be planted in an indoor growing bed, I am unclear on the proportions of the various soil amendments to add. I intend to make up my own potting mix as I need at least 50 cubic feet to fill the space. At 10.00 per ft, the bagged mixes can become quite expensive for that amount. I don't want to use local topsoil as it's not pasteurized though, and baking that amount in my oven is impractical. Thanks for any advice!
