Description: Copiapoa laui is a miniature, clustering copiapoa. It is the smallest species in the genus, this was only discovered in the 1970s.
Cultivation and Propagation: It is a summer-growing species fairly easy and robust to cultivate, but very slow growing.
Growth rate: Slow-growing.
Exposure: It is suited for sunny-brightly exposure but can tolerate light shade. However, it will do its best only with lots of sun and become stressed with inadequate light which could result in poor growth and unnatural shape. It has a good heat tolerance.
Watering: Waterings should be rather infrequent to keep the plant compact and avoid its becoming excessively elongated and unnatural in appearance.
Special need: It is suited for airy exposures. Provide very good ventilation. Nearly all problems occur as a result of overwatering and poor ventilation, especially when weather conditions are dull and cool or very humid. They must have very dry atmosphere.
Hardiness: It likes warmth (recommended minimum winter temperature 5° C) But plants kept perfectly dry can easily survive a light frost.
Reproduction: From seed, plantlets, or grafted.
