Fertilizer provides brain cactus with the nutrients it needs to grow and bloom. The plant should be fertilized every two weeks during the growing season (spring and summer) with a balanced fertilizer such as 10-10-10. Be sure to follow the manufacturer’s instructions on how much to apply. During the fall and winter, brain cactus should be fertilized monthly with a low-nitrogen fertilizer such as 5-10-5.
