Care: Opuntia humifusa is easy to grow and requires very little maintenance. It is an incredibly hardy plant that tolerates almost all weather. For best results, all it requires is a sunny location with 6-8 direct sunlight and, free-draining soil, and good airflow. Water once a month indoors. The best temperature range for this cactus is between 65-90°F (18-32°C). You don’t need to fertilize your plants if they are grown in the garden, but an application once or twice a year can be beneficial.
Watering: Requires only a small amount of water. It prefers dry soil and although it will cope with long spells of wet weather, it will not thrive in them.
