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.
A small, desert cactus is perfect for an office desk. Your desk is probably like most office spaces, with warm and dry air, fluorescent light fixtures and subject to random drafts from the door, air conditioning or heating ducts.ater your plant in the sink when the soil is dry to a depth of 3 to 4 inches, allowing the excess water to drain from the flowerpot before returning it to your desk. Place the flowerpot on a tray filled with pebbles and water to provide extra humidity for these tropical cacti.
