the genus pachyphytum belongs to the crassulaceae family. the moon stones (pachyphytum oviferum) are native to mexiko. its orange to red flowers are shown in spring.
care
pachyphytum oviferum does best on a sunny location. but it also grows on a bright to light shaded place. during summer it can be placed on the balcony or in the garden. but make sure that rainwater can easily run out of the pot because sitting in water will cause rotten roots.
a standard cactus soil or a mix between humus, sand and gritty (2:1:1) can be used. if the plant is in active growth (spring to fall) it can be deep watered. whats running out of the pot’s hole must be removed after a few minutes. before adding water next allow to dry.
the moon stones can be fed monthly with a half diluted cactus fertilzer if they are in active growth. recently bought or repotted plants don’t need to be fertilized for the first six to eight weeks.
for showing its inflorescence in spring, a cold winter location may be helpful. pachyphytum oviferum can be placed at 5-10 °c (41-50 °f). at this temperature range it has to be kept nearly dry, a fertilizer must not be given. if placed at room temperature during winter, give it as much light as you can.
propagation
moon stones can be propagated by seeds, leaf or stem cuttings.
