Living stones: understanding Lithops and supporting leaf replacement

Your care table

Small bodies with remarkable patterns

Several low plants sit in the 8.5 cm pot. The total height of approximately 8–10 cm includes the pot; the bodies themselves project only slightly above the compost. Fine lines, spots and a central fissure mark their upper surfaces. The offer names no individual species or forms. Neither a specific flower colour nor identical patterns in every delivery is therefore promised. The close-up reveals details without turning them into large stone balls.

Two leaves form a head

Lithops belong to the Aizoaceae family, not the cacti. A single head consists of a closely joined leaf pair. The next leaf generation develops inside while the old leaves gradually give up their reserves. Some plants form two new heads in the process and branch slowly. A blanket statement that an entire plant always has only two leaves would therefore be too simple. A bowl with several heads may also contain multiple individual plants or branching specimens.

Plenty of light and good air movement

A very bright, sunny position is important. Nevertheless, acclimatise gradually to strong sun after transport or winter conditions. The small surface can burn behind hot glass. Good ventilation and protection from extreme trapped heat help in summer. Too little light can produce elongated, unnatural bodies. A warm outdoor position sheltered from rain is possible temporarily, but uncontrolled rain does not suit targeted watering. Keep bright and frost-free in winter.

Leaf replacement determines the watering pause

When new leaf pairs form inside and old ones shrink, reserves are being transferred. This is not automatically a cry for water. During this phase, keep mostly dry until the old coverings are largely thin and papery. Do not try to maintain several thick leaf generations by regularly adding water. Only afterwards, and when activity is recognisable, resume careful supply. Do not forcibly pull away old coverings. With several plants in one pot, examine each individual’s development.

Water according to growth, not weekday

Outside leaf replacement, water selectively during active growth and let the root ball dry again. A weekly summer appointment does not automatically fit: very hot periods can slow growth. Damp compost then increases the risk for resting plants. Normal watering is largely suspended during winter leaf replacement. A very free-draining mineral-based mix and drainage holes are essential. Feeding remains sparing and belongs, at most, in the active growing phase. An individual small shrinking old head must be assessed together with the annual cycle, compost moisture and new leaf pair.

Support repotting and flowers with patience

When needed, repot carefully at the transition into an active phase without unnecessarily damaging stronger roots. A sufficiently deep small pot is better than a shallow decorative bowl that stays wet. Do not divide healthy heads in the name of supposed rejuvenation. Seed is the usual means of propagation; seedlings need their own finer cultivation and must not follow the dry schedule for adult plants. Flowers may emerge from the fissure, but are not guaranteed annually on every specimen. Translucent, soft bodies collapsing above wet compost are instead warning signs of rot.
