How to fertilize Mammilaria Spinosissima
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Mammilaria Spinosissima after it doubles in size or once a year—whichever comes first.

Leaning cactus help. My daughter bought this cactus years ago when she was going to plant a succulent garden then promptly lost interest. I have kept it alive, but not given it much attention. It’s developed a pretty serious lean. What would you all recommend to help it live its best life?
