Select your region to see how the current weather in your area affects the placement of Rainbow Cactus in your home 🏡.
Most potting soils come with ample nutrients which plants use to produce new growth.

To replenish this plant's nutrients, repot your Rainbow Cactus after it doubles in size or once a year—whichever comes first.
