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.

I just watered it today and it hasn’t been watered for about a week and a half. Will it be fine?

Questions! Hello! I have recently gotten back into keeping succulents. I've done a lot of research this time, all my cacti are planted in 50% succulent soil and 50% perlite mix. The larger boobie cactus I bought from a nursery a few days ago. The man at the nursery said to wait a month to water it after I repot it. The smaller boobie cactus and the verigated moon cactus were bought today. They were in super moist soil. Those have been repotted as well. The lithops is in a 80% perlite, 20% succulent soil mix. It was repotted 2 days ago and I haven't watered it. The rest of the succulents are in 60% succulent soil, 40% perlite mix. Those have all been repotted within the last week, so none of them have been watered yet either. They are all in an east facing bay window that gets about 4 hours of direct morning sun. Today I set up a full spectrum grow light. I plan to run it for 12 hours (in conjunction with the natural sunlight). I am going to start with the low intensity and then ramp it up to full brightness over the next week. I plan to bottom water them when the time comes. Every planter has several drainage holes. Is there anything I could do or need to do better? I plan on watering once the soil is completely dry. I am using bamboo skewers for moisture monitoring. Thanks in advance for taking the time to read #succulentlove #growlights #newplantmom #succulentsquad #cactusclique

Hi #MoonCactus

So I am new to this app and have only grown a few things. My cactus is turning yellow at the base and spreading across now. While all my other plants next to it on the same schedule and sun light are doing great. What causes this? #MoonCactus

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

It’s a cactus! Super easy to care for. I’ve moved it to a pot with another cactus and succulent and it seems to be doing well. I just let them hang out on my windowsill and do their thing. Nice, easy plant to have around.

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!

This moon cactus is fairly new to me, so far she is a survivor. I have always wanted one so I ended up getting her for hardly anything. I think I paid $1.75 since Krogers had their plants on sale for 50% off.

these plants are kind of doomed to live a short life just because of the nature of the plant(s)
pretty to look at but would definitely not recommend for beginners
