My moon cactus has gone virtually unchanged in the almost year I’ve had it. Super hardy and always colorful. Imperceptibly slow grower, which can be good or bad depending on what you want out of it!
It’s gorgeous and has lots of color variety. Very easy to care for just don’t overwater it out in harsh sunlight. A window sill will be just fine :)

The moon cactus is as sturdy as they come! and comes in a variety of colors! I would recommend this for plant lovers or first time caretakers.
this plant is very easy to take care of bc it’s low maintenance. it doesn’t gain height fast, but the spikes grow kinda fast

You have to keep the soil moist, but it can stay moist for a good amount of time. Don’t water it if the soil is moist
they’re very pretty and very forgiving for forgetful plant parents that miss watering days.

How to fertilize Moon Cactus

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