Expert tips
The key tip
Crassula sarcocaulis miniature flowers generously if well-drained: water lightly once a week during growth (May-September), very sparingly in winter unless heated indoors.
The common mistake
Growing it in a pot that's too large without proper drainage: the soil stays wet and stresses the plant, suppressing flowers.
The pro's trick
Take stem cuttings in June, let them dry for two days, then insert them into dry sand.
Care
Watering
Water moderately during the growing season (spring-summer), allowing the substrate to dry between waterings. Drastically reduce watering in autumn and winter—once a month is sufficient. Waterlogging is the main enemy: prefer a well-draining pot and err on the side of too dry rather than too wet.
Light
Place your crassula in full sun to promote growth and flowering. At least 6 hours of direct sunlight daily is recommended. Lack of light causes etiolation and weakens the plant; indoors, position it near a very bright window.
Soil and substrate
Use a specific succulent mix or prepare a mineral-rich blend: cactus soil, pumice and coarse sand. Add gravel at the bottom of the pot to improve drainage. An impoverished and porous soil is preferable to rich, compact potting soil.
Pruning and care
Pinch young stems in spring to encourage branching and maintain a compact shape. Remove dead or damaged leaves and air out the centre of the plant in winter. This plant requires minimal regular pruning—favour light shaping instead.
Fertiliser
Fertilise very lightly once or twice during the growing period (April to August) with diluted succulent fertiliser. Respect recommended dosages: excess nitrogen promotes soft growth susceptible to pests. Stop all feeding in autumn and winter.
Pests and diseases
Watch for scale insects or spider mites, especially indoors. Excess humidity promotes root rot and fungal issues. Ensure good air circulation, avoid spraying the foliage and immediately isolate any affected plant.
Did you know?
The genus Crassula takes its name from the Latin crassus (thick), referring to its fleshy leaves. Crassula sarcocaulis is prized as a succulent bonsai in Asia, where its natural branching and small size make it a favourite subject for botany enthusiasts who love minimalism.
Where to buy it
Plant in spring, once all risk of frost has gone. Pick a plant with healthy foliage and roots that are not exposed. Best time: from April to June.
