About trees
Lithops spp. are small succulents from southern Africa with a pair of thick leaves joined together, resembling stones. The central fissure is where the new leaf pair and flowers emerge. Color, window markings, and form vary by species, so keep the name at the genus level when the exact species is not known. An important part of the plant's cycle is that the new leaf pair gradually uses stored water from the old leaves, which naturally wrinkle and dry. Do not pull or cut the old leaves until they are completely dry. With suitable light, the plant remains short and compact, while abnormal stretching usually indicates insufficient light during growth.
Use a highly mineral, very fast-draining growing medium and a pot that does not retain water. Watering should follow the plant's growth cycle rather than a fixed schedule. Avoid watering while the new leaf pair is drawing water from the old leaves, and water cautiously when active growth begins. Provide high light while acclimating gradually to sun, together with good air movement and protection from prolonged rain. It suits a small collection where the surface markings can be viewed closely. Observe leaf firmness, the central fissure, and the timing of leaf replacement before watering, because excess moisture can quickly damage the roots and stem.
