Soil
Adam's Needle is very sensitive to wet soil, so choose a potting soil that drains very well and doesnât 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!

Adam's Needle grows very slowly and doesnât require added fertilizer. Replacing your plantâs potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
