Arendt's Hedgehog 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!

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