Finding light for Moon Cactus in your home
Moon Cactus love being close to bright, sunny windows 😎.
Place it less than 1ft from a south-facing window to ensure it receives enough light to survive during this time of reduced sunlight intensity in Washington, District of Columbia ⛅.

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.

Moon Cactus is not known to cause harm to humans or pets. Regardless, if you, a family member, a cat, or dog has ingested any plant material, please consult a doctor or a veterinarian.
Moon Cactus 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.
Moon Cactus 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!
Moon Cactus 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!
Moon Cactus is native to South America.
Moon Cactus produces flowers in the wild, but does not flower when kept as houseplants.
Moon Cactus grows vertically and new growth will emerge from the top of the plant.
USDA Hardiness Zone
Moon Cactus can be grown outdoors in USDA Hardiness Zones 10-12b. Find your local hardiness zone here.
Moon Cactus can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot
Overwatering is a likely cause of issues with Moon Cactus. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.
Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!

What other plant parents say
Don't buy this parasitic couple if you're using an indoor grow light...if it's too late then they need direct light on its base and not the colorful top so get your Lego sets out and start building a small house to both hide and help your moon cactus stay happy under direct light ...i used a tall plastic water bottle for a bit because the cap was blocking enough light...sure it's pretty but at what cost...they don't even like each other
love my moon cactus, they look so cool and THEY’RE RED!! I love red. super easy to take care of because it’s a cactus so it doesn’t need a ton of attention and only needs to be watered occasionally but they do tend to die kind of quickly. with my first one, the cactus drank up all the water wayyy too quickly and the red bulb at the top filled with water and it ended up dying after about 7 months. my new one has survived a good six months so far but the bottom that is partially in the soil is starting to wilt. it’s limp and brown but i’m hoping some good old tlc will revive it.
The colorful part and the green part are actually two separate cacti! The colorful one can’t produce chlorophyll, so it’s grafted to the bottom one! It’s actually parasitic, but if the bottom cactus begins to show signs of dying, the top can be removed and re-grafted to a different host to save both cacti!
