How to Grow and Care for Curio sulcicalyx
Light: Keep Curio plants in partial shade if outdoors, which is their preference in summer, and bright sunlight if indoors. They will grow in full shade but will become lank and leggy.
Soil: These plants prefer well-draining soil. For growing Curio indoors, using a container with at least one drainage hole at the bottom is essential.
Hardiness: Curio sulcicalyx can withstand temperatures as low as 25 to 50 °F (-3.9 to 10 °C), USDA hardiness zones 9b to 11b.
Watering: Curio plants are drought tolerant, but the soil should never be left dry for too long. They need some water during the growing season, but be careful not to leave the soil wet for prolonged periods.
Fertilizing: The members of this genus can take a bit more fertilizer than other succulents if you want them to grow fast.
Repotting: You do not need to repot Curio plants often. You can do it when the container becomes too small or shallow.
Propagation: These plants can be grown from seeds or cuttings.
