Mini-Cactus Plants

The cactus family includes a huge variety of succulent plants which change color and size. Some develop into tall columns, reaching around 50 feet high, while some are only a couple inches high and well-suited for growing in pots. All these mini-cacti generally create brightly coloured flowers and take on interesting shapes. You can buy mini-cacti already potted in tiny containers; with appropriate care they can develop indoors while adding color and interest to your room.

Light Requirements

Since mini-cacti are succulents and create colorful blossoms, they require about four hours of direct sunlight each day. A good indoor place is in 4 feet of a south- or east-facing window. Mini-cacti need sunlight exposure evenly, so rotate periodically to make sure that the entire plant receives sunlight. You can tell if the plant receives too much sun by taking notice of its color. Rather than green, the cacti appear white or yellow. Should you have to move a cactus in a high-light area to lower light, do it gradually.


Mini-cacti need well-drained dirt and enjoy other succulents, they don’t need as much water as other plant varieties. Careful observation will be able to help you figure out a watering program for your own mini-cactus. As a rule of thumb, add water once the top half-inch of soil feels dry. When watering, moisten the soil thoroughly, letting it soak up the water, and if it does so rapidly, add more water until it comes from the drainage holes. Many cacti have to be watered once a week.


Mini-cacti are not heavy feeders, so that they require little fertilization. During active development, it is possible to feed the plants using a low-nitrogen 5-10-10 fertilizer every two or three months. Feeding using a time-released fertilizer is also an option, but only feed the mini-cactus after during spring. You should never fertilize un-rooted or newly re-potted plants.

Winter Care of Mini-Cacti

Mini-cacti go through a dormant period in winter. In this period the cactus requires little or no water. The plant does well using a watering every few weeks. You don’t have to fertilize the cactus because little development occurs during that time. During active growth, cacti require an indoor temperature between 65 and 90 degrees Fahrenheit. During the period, place cacti in a room with a temperature between 45 and 55 degrees.
