Cultivation
Lithops herrei L.Bolus var. geyeri is relatively easy to care for, making it a great plant choice for the inexperienced gardener. It thrives best in sandy or rocky soils, which mimic its natural habitat, and requires very little water. A well-drained potting mix and a spot with bright but indirect sunlight will suffice for a potted plant. When it comes to watering, it is important to wait until the soil is completely dry before adding water, as too much moisture can cause the plant to rot. A light fertilization combination includes - equal parts of coarse sand, peat moss, perlite, and vermiculite. The plant is generally propagated from seeds, since its clumping habit and slow growth rate make division of the clumps hard. Additionally, living stones may be appealing to pests like mealybugs, spider mites, and aphids, so regular inspections and/or treatments may be required to avoid infestations.
Light Requirements
Lithops herrei L.Bolus var. geyeri (Nel) de Boer & Boom prefers bright, indirect sunlight. Place the plant near a south-facing window where it can receive 4-6 hours of sunlight in a day. Direct sunlight can scorch the leaves, so it is important to provide filtered light. If growing the plant outdoors, provide shade during the hottest part of the day.
Temperature Requirements
The ideal temperature range for Lithops herrei L.Bolus var. geyeri (Nel) de Boer & Boom is between 20-27°C (68-81°F) during the day and 10-15°C (50-59°F) at night.

Propagation of Lithops herrei L.Bolus var. geyeri (Nel) de Boer & Boom
Lithops herrei L.Bolus var. geyeri (Nel) de Boer & Boom, commonly known as Geyer's living stones, is a fascinating succulent plant native to Namibia. The plant is named after Hermann Wilhelm Rudolf Geyer, a German botanist who collected the first specimen in the early 20th century. Propagation of Lithops herrei L.Bolus var. geyeri is relatively easy and can be accomplished by several methods.
Propagation from Seeds
Propagation of Lithops herrei L.Bolus var. geyeri from seeds is the most common method. The seeds of this plant are very fine and require careful handling. Sow the seeds in a well-draining soil mix and cover them lightly with sand. Water the soil gently to avoid washing away the seeds. Keep the soil moist but not waterlogged and place the pot in a warm, bright spot. Germination may take several weeks to several months. Once the seedlings have developed two true leaves, they can be transplanted into separate pots.
Propagation by Division
Propagation of Lithops herrei L.Bolus var. geyeri by division is another method. This method involves separating the offsets, or "pups," that grow alongside the mother plant. Wait until the offsets have developed their own roots and then carefully remove them from the mother plant. Plant the offsets in a separate pot filled with well-draining soil mix and water gently. Keep the newly potted offsets in a shady and humid area, out of direct sunlight, until they have rooted in.
Propagation by Cuttings
Propagation of Lithops herrei L.Bolus var. geyeri by cuttings is not recommended because the plant is prone to rot when cut. The plant's leaves are fused to the stem, and cutting through the leaf to separate the bud from the mother plant can introduce disease and kill the plant.
In conclusion, propagation of Lithops herrei L.Bolus var. geyeri can be carried out successfully by seed and division methods, but avoid propagating by cuttings. With proper care and patience, propagating this succulent plant will reward you with a beautiful collection of Geyer's living stones.
