The ideal exposure is full sun most of the day, which intensifies the color of its leaves and improves growth. In very hot climates, partial shade is recommended during the most intense hours of sunlight to prevent sunburn.
- En exterior, ideal for balconies, terraces, patios or rockery gardens.
- En interior, place near well-lit windows or spaces with intense indirect light.
Withstands wide temperaturesIdeal temperatures range between 18 and 28 degrees Celsius, although many species can withstand extreme heat and light frosts if the substrate remains dry. If the temperature drops significantly during the winter, it's important to bring it indoors.

Propagation and reproduction of Graptopetalum
The Graptopetalum It reproduces very easily in the following ways:
Propagation by stem or leaf cuttings
- Stem cuttings: Carefully cut a piece of stem with several leaves. The incisions should heal for several days in a dry, shaded area until a protective callus forms.
- After this time, plant the cutting in a dry, well-aerated substrate, avoiding overwatering until the first roots appear.
- Do not expose newly planted cuttings to direct sunlight; keep them in semi-shade until they root (approximately 2-3 weeks).
Leaf cuttings They also allow you to obtain new plants: separate an entire leaf, let it dry for a few days, and place it on the substrate. After a short time, it will develop roots and a new rosette.
Propagation by seeds
- Use trays with light substrate and a mixture of sand and soil.
- Spread the seeds superficially, without piling them up, and cover with a minimal layer of substrate.
- Maintain the right amount of moisture and avoid waterlogging. Seeds usually germinate within 10 to 15 days if the temperature is between 18 and 24°C.
Once they've germinated, carefully transplant them into individual pots. It's a slower process than propagating by cuttings, but equally effective.
