Nutrient, fertilizer, and repotting needs for Cactus: repot after 2X growth

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 Cactus after it doubles in size or once a year—whichever comes first.
