Thimble Cactus enjoys lots of humidity. Provide humidity for your plant by watering regularly and thoroughly, since plants absorb most water through their root system rather than their leaves. They may also benefit from being placed next to a humidifier.

🪴 Soil

Thimble 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 Thimble Cactus →


💩 Fertilizer

Thimble 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!


❄️ Dormancy

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


🌎 Native Region

Thimble Cactus is native to the Southwestern United States, Central America, and the Caribbean.


🧐 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.

This plants has small roundish growths. It is easy to separate or if any of them fall off it’s just as easy to place in the soil. Love the flowers to when it does bloom.
