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.

🐶 🐈 👶 Toxicity

Star 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.


💨 Humidity

Star 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.

Star Cactus Humidity Needs →


🪴 Soil

Star 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!

When and How to Successfully Repot Star Cactus →


💩 Fertilizer

Star 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!

How Much and When to Fertilize Star Cactus →


❄️ Dormancy

It’s common for Star Cactus to go dormant in the summertime and you may notice their growth slow down. Waterings should be spaced out more during this time.


🌎 Native Region

Star Cactus is native to Southern Africa.


🌸 Flowers

Star Cactus produces flowers in the wild, but does not flower when kept as houseplants.

🌱 Propagation

Star Cactus can be propagated by the leaf method. To propagate:

  • Remove a leaf by gently twisting until it pops off.
  • To get the leaf to root, you can either:
    • Place the leaf in water until roots emerge and are ~2” long and then transplant into well-draining soil, or
    • Place the leaf directly into well-draining soil

How to Propagate Star Cactus →


🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

Inspect the soil moisture; too dry or too wet soil can cause problems.

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.


😖 Common Issues

Overwatering is a likely cause of issues with Star 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!

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

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

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.
