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.
The true leaf of cactus is spine and the leaves develop in small notches in herbaceous stem. Herbaceous varieties of plants are beautiful additions to a garden because of colorful foliage. This plant has a green stem, which is soft and tender. Most of the plants are annuals while some are seasonal and perennial.
