About 5 years ago, Sheridan Cleland of MyPDFscripts wrote the below article on his blog. Soon after, the site disappeared. I wanted to keep the memory alive, because these practices by the studios have not changed. They have only become worse.
Cacti are one of my favorite types of plants to grow inside all year and outside in summer. Unfortunately, the ambient air tends to stay moist during most seasons, a condition which makes cacti unhappy. Cactus potting soil can enhance drainage, increase evaporation and provide the dry conditions that cacti favor.
Gravel and then potting mix is added to a shallow dish in making a cactus garden dish. Sprinkle a thin layer of gravel into a seed tray. Most cacti have shallow roots, since they store water in their stems. Add 1â2 in of cactus potting mix, and make holes for the plants. Cover your cacti with clear plastic bottles or containers to keep them warm.
