π§ How to Water
Allow the substrate to dry out completely between wateringsβdip your finger 2-3 cm into the soil to check.

Avoid intense direct sun for long periods, especially in hot climates, as it can cause burns and reddish/brownish spots on the leaves.
πͺ΄ Ideal Soil
Use a mineral and well-draining substrateβmix cactus/succulent soil with plenty of perlite, pumice, or coarse sand (about 50% or more inorganic material). The ideal pH is between 6.0 and 7.5. Always plant in pots with drainage holes.
