Care Guide

Blossfeldia cacti are relatively easy to care for and can be grown indoors or outdoors. They prefer well-draining soil and should be watered sparingly, allowing the soil to dry out completely between waterings. Blossfeldia should be fertilized once a month during the growing season with a cactus-specific fertilizer. They require full sun and can tolerate temperatures as low as 30 degrees Fahrenheit, making them hardy to zone 9a.

Blossfeldia cacti are generally hardy and resistant to pests and diseases. However, they can be susceptible to mealybugs, spider mites, and scale insects. These pests can be treated with a solution of dish soap and water or with a commercial insecticide. Blossfeldia can also be affected by root rot if overwatered, so it is important to ensure that the soil is well-draining.
