Mountain Ball Cactus is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.


💨 Humidity

🪴 Soil

Mountain Ball 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!

🌱 Propagation

Mountain Ball Cactus can be propagated by the stem method. To propagate:

  • Make a cut just above the node. The node is the break in the stem where the leaf emerges.
  • To get the cutting to root, you can either:
    • Place the cutting in water until roots emerge and are ~2” long and then transplant into well-draining soil, or
    • Place the cutting directly into well-draining soil and water when dry.

🧐 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 Mountain Ball 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!

This guy is a beast. If you forget to water a plant, A CACTUS is the answer. But if you’re the person who over waters a plant make sure you have drainage with a cactus or else it will die. Only thing i worry about is pets going to sniff it and pricks their nose. I’m on my toes when my pets are close by to my cactus. But overall not a hard plant to take care of!
