How to Grow and Care
Melocactus are somewhat finicky cacti with unusual requirements. They shouldn't be allowed to completely dry out, even in winter, and they can suffer from soil composition, drainage, water level, sun, and more factors that are difficult to control. For that reason, these plants are best for growers who have already had some success cultivating cacti. Establish a balance with good aeration matched by ample water good soil matched by good drainage, and these plants should continue to grow. If they are grown successfully, their unusual tops make them among the more beautiful desert cacti.
Notably, Melocactus like to be fairly packed in, so keep them in a fairly small container that slightly constricts their roots. Repotting them at the beginning of the growing season is a good idea until they form cephalium, and the body stops growing, and they should be repotted like other cacti.
