Choosing the best soil for Lithops is crucial to prevent root rot and ensure long-term survival. Lithops, also known as “living stones,” are unique succulents that require extremely well-draining, gritty soil to mimic their natural arid habitats.

When selecting soil for Lithops, prioritize low organic matter, high mineral content, and fast drainage. A poor, rocky mix prevents moisture retention, essential since Lithops are prone to rot.

Whether you’re growing Lithops aucampiae, Lithops karasmontana, or Lithops optica, the right soil ensures they remain compact and healthy.

This guide will explore the top 10 soil mixes tailored for Lithops, focusing on drainage, aeration, and mineral content to help your living stones flourish, from gritty blends to specialized succulent mixes.
