Pincushion Cactus Information
Pincushion cacti are small, squat plants that usually don’t grow more than 6 inches (15 cm.) in height. They can be ball or barrel shaped, and are native to the warmer regions of the United States. The pincushion cactus plant is most commonly grown indoors but it can tolerate some chilling temperatures if grown outside. Pincushion cactus is so called because it is covered in white spines over the entire surface of the plant. It is a very prickly little specimen that is best handled with thick gloves.
Growing Pincushion Cactus
Pincushion cactus care is very simple and suitable for the beginning gardener. Cactus plants are used to dry conditions and limited fertility. The soil for a pincushion needs to be well drained and gritty. The soil needs to dry out between watering, which is best accomplished with a sandy topsoil. The cactus goes dormant in winter and needs no additional irrigation until spring. Potted plants do well in unglazed clay pots, which allow any extra moisture to evaporate.
Temperatures should be between 50 and 75 degrees F. (10-24 C.). Small gravel spread around the base of the plant out to the root zone will act as a mulch to deter stem rot.
The cactus produces offsets when it is mature. These can be divided from the mother plant and potted in a sandy soil mixture. You can also start the plants from seed in spring. Plant seed in a flat filled with cactus mix. Surface sow and then sprinkle sand lightly over the top and moisten the soil evenly. Place the flat in a warm location of at least 70 degrees F. (21 C.). Keep seeds wet when growing pincushion cactus. Seedlings are transplanted when they can easily be moved.
Flowering Pincushion Cactus
If optimum heat and watering conditions are met, the pincushion cactus may reward you with flowers in spring. Enhance the chance of blooming by holding off watering until several weeks into spring. You can also apply a cactus food in early spring to give the plant the nutrients it needs to produce blooms.
