🪴 Soil

Star Plant 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!

🧐 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.

I love cacti like this one because they never die. Has been brown at the bottom for probably a year now and not sure why but it’s still fine

This is a great resilient plant, it looks very cool and it does well on a windowsill.

They don’t grow very quickly but they also do not provide much care. Just place them in a window and forget them for awhile, come back to ‘slightly’ bigger cactus!
