How to fertilize Ruby Ball
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 Ruby Ball after it doubles in size or once a year—whichever comes first.

Ruby Ball prefers dry environments. Providing extra humidity or misting your plant allows water to linger on leaves, which can create the perfect environment for harmful types of fungi.
Ruby Ball is very sensitive to wet soil, so choose a potting soil that drains very well and doesn’t retain too much moisture. A good soil will have lots of perlite or vermiculite for drainage and some organic matter for nutrition. A few handfuls of perlite added to regular store-bought cactus soil will do the trick!
Ruby Ball grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Ruby Ball is native to South America.
