Houseplant of the Week: Cacti

Posted on by

Found in an amazing array of shapes and colors, cacti are those succulents that even the blackest of thumbs have a hard time killing. The cactus family (Cactaceae) is considered one of the most distinctive and specialized groups in the plant kingdom, which includes about 2,000 species!

What do you need to grow cacti? A sunny spot, well-draining soil and not much else. The big trick with cacti is not overwatering them.

All cacti are part of the succulent family of plants, meaning that their stems are designed to hold water in case of a drought. When the plant is dry it uses those reserves. But if you overwater, it can cause the plant to rot.
