Finding light for Star Cactus in your home
a window
Star Cactus may have difficulty thriving, and will drop leaves 🍃, without ample sunlight.
Place it less than 3 feet from a south-facing window to maximize the potential for growth.
Select your region to see how the current weather in your area affects the placement of Star Cactus in your home 🏡.
How to fertilize Star 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 Star Cactus after it doubles in size or once a year—whichever comes first.

What’s up with my Star Cactus? All of a sudden, like over the past few days, my Star Cactus has been changing colour from green to that burgundy-ish and possibly looking a little sad. It’s in a very gritty succulent soil and terracotta pot with a drainage hole. I’m quite sure overwatering isn’t the culprit. I also don’t see any obvious signs of pests (although a craggy plant like Drake is tricky to properly inspect). We’re entering autumn in Southern Ontario and it’s been a little grey and rainy so it’s been less bright but he’s indoors and it’s not his first season change so I’m not sure that’s it either. Your thoughts and/or advice are very welcome .

What is going on??? Making the round and saw this. Is it too top heavy? Should I cut it?

Sally is looking a little sad :( Hi! So I’ve had my star cactus a little over half a year now. Since I’ve had her, she’s slowly started looking more and more dehydrated. She’s still alive but definitely struggling. When I put her in direct sunlight she shrivels up but when I take her out of the direct sunlight, she also shrivels up. Help! What should I do? I water her about every ten days. Should I repot? #HappyPlants #SucculentLove #NewPlantMom

I need help from people who know how to protect their plants from swampy, humid apartments with no air flow 😭 I have lost so many plants this month I have literally cried. Snake plants and succulents just melting into puddles of gelatinous goo from the disgustingly oppressive humidity in here. I didn’t even know that was a thing that could happen from being in an overly humid environment—I was looking for patches of mold and stuff like that… Not rotting plants. We are struggling financially (NY is the 3rd most expensive place to live in the US—why was I born here?) but managed to find a window air conditioner for cheap which we’re putting in today. I can’t afford to buy fans or anything else to improve the air flow so I’m hoping the AC helps. This is the latest victim. Anyone who knows me knows I take good care of my succulents and do not overwater or do anything that would cause this, and I’ve successfully had them for long before we moved to this sweat box apartment, so please no strangers suggesting that—I know people mean well but it’s not the case and I’m genuinely devastated at the plants I’ve lost this month 🥲 This is all that’s left of my cathedral windows haworthia. I gave a substantial portion away before this happened so at least that’s out there, living. Any cheap or free tips to help my plants survive a swampy NY summer would be much appreciated. They got spoiled with central air before this. 😭😭😭 I’m going to bring a lot of them to work, but I can’t bring them all #GregGang #PlantGraveyard #babevila #thissucks

Over watered? Hi, is my star cactus over watered? The leaves are squishy and thin. I think my coworker has been secretly watering it. #succulents

Why is it red? #Haworthia

More or less water? #Haworthia My star cactus is on the struggle bus a little. The tips of his growth are shriveled in. Am I overwatering him or is he shriveled because he's not getting enough? When I water him, his pot never drains any water and is always fairly dry on top.

To cut or not to cut? Hello All, i have a Star Cactus that seems to have grown a 2-foot stem. It hasn't flowered yet, and it's been about a week. It grew super fast. Do I cut the stem or leave it? Does it need a bigger pot? It's in a 2" pot currently. Thank you for your help!! #succulents #starcactus

I loved this little guy, and then one time I overwatered and let water sit in the soil. It just immediately rotted completely.

* This plant sits in a west-facing window sill. I water it about every 10 days or so.
I like this plant, it's not one of my favorites, but I like this plant. It is very easy to care for. It just sits there and doesn't bother anyone. It's very unique looking. Because of my set-up, I bottom water it. I am anticipating having to repot it soon seeing that it fills up the entire plastic pot now.

I love this little succulent. The leaves are soft and you’ll know you’re doing something right when the plant opens up a bit. This plant has the capability to produce multiple plants/buds

This is an interesting succulent haven’t had it long but it’s quite tolerant and it’s different. 😊

This plant just minds its own business and sits happily growing with little attention. And it’s so cute!

one of my first succulents and a great one for a beginner, as it’s pretty, easy to care for and grows quickly, you even can see the water inside of the leaves! Mine is named Amelia and is incredibly large now and I love her dearly, but make sure to move away from direct sunlight as once they grow bigger they brown much quicker

My cat knocked it over and it was out of a pot for about 2 weeks and was still perfectly fine once repotted.

was bought from a big box store and had all of its roots tangled in a mesh that made it impossible to grow. It was bought several years ago though and shes still surviving.
