What Plant Is Crassula rupestris? This Article Introduces It
Crassula rupestris is a succulent of the Crassulaceae family, genus Crassula, native to Namibia in Africa. It grows fast and has strong adaptability, and also tolerates partial shade, but does not like water, so be careful to water less when planting. It is widely cultivated around the world. It is very suitable for planting in combinations, because it grows fast and will quickly cover bare spots! Planted alone, the effect is slightly inferior to combinations, with a single tone; if the flowering period is chosen well, it will look very beautiful when matched together!

Care Tips for Crassula rupestris
Potting soil: repot every year in early spring. Use a mixed soil of leaf mold, culture soil and coarse sand, with a small amount of bone meal added. In winter it enters a semi-dormant state; keep the potting soil dry.
Watering: water once a week during the growing season, and once every 2-3 weeks at other times, keeping the soil merely moist.
Fertilizing: fertilize once a month with diluted cake fertilizer water or "Huiyou" 15-15-30 special fertilizer for potted flowers. Do not fertilize in winter.
Pests: when indoor ventilation is poor, the stems and leaves may already be harmed by red spider mite. When this occurs, spray with 40% omethoate emulsifiable concentrate at 1000 times dilution to kill them.
Propagation Methods for Crassula rupestris
Cuttings: rooting is fast and the survival rate is high when done in spring and autumn. Select relatively neat branches with tightly arranged scale-like leaves. Cut them into 12-15 cm lengths, insert them into a sand bed, at room temperature 21-24°C. They root 20-25 days after insertion, and are potted up 1 week later.
