😖 Common Issues

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

Cut your plant just past where the rot ends and allow it to callus over for a few days before replanting it in fresh, dry soil. Download Greg to make sure your plant never gets overwatered again!
