Very low maintenance, only needing water every week or two, and not being highly sensitive. Many of my plants are over dramatic and “faint,” wilt, or yellow when I slightly vary on watering schedule/…

Cactuses don’t need water everyday! Perfect for people who don’t have a lot of plants. Love how they look in my room. Definitely something I need more of!

How to fertilize cactus

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.
