🪴 Soil

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!

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.

Overwatering is a likely cause of issues with Sempervivum Arachnoideum. These plants are very sensitive to wet soil so if you notice your plant becoming squishy or translucent, overwatering is the likely culprit.

When we first got it the little offshoots fell off the main plant so we stuck them in a different little pot and they all took! We didn’t expect the main one to thrive after a lot of the offshoots fell off but it’s doing great.
