Pachyphytum is a genus of slow-growing succulents in the family Crassulaceae native to Mexico. They are shrub-forming or stemless rosettes that eventually form clumps. Leaves are plump and juicy and may have a powdery coating called farina. They range in color from green to lovely orange and even purple. Flowers are bell-shaped, usually greenish-white and deep red, and grow on long, spiky inflorescences. They appear in spring and summer. The rosettes will not die after flowering.
The generic name "Pachyphytum" comes from Greek and means "thick leaves."
Growing Conditions
Pachyphytums will not tolerate frost well. Temperatures below 20°F (-6°C) will kill the plants, and temperatures that drop below 45°F (7°C) for an extended period should be avoided. These succulents tolerate high heat and intense sunlight. Like most Crassulaceae members, Pachyphytums can tolerate (and even appreciate) poor soil as long as it drains well. They thrive in full or partial sunlight.
Allow the soil to dry before watering, and avoid getting water on the leaves. The plants will require more water in winter as they begin their active growing season. If you are unsure when to water your Pachyphytum, watch the lowermost leaves for signs of drying out, then water. Pachyphytums are far more likely to survive underwatering than overwatering. The leaves will appear wilted and slightly "under-full" when they need water.

Propagation
Pachyphytums are easy to propagate from stem cuttings or a single leaf. First, leave the leaves in the open air for a day to allow the wound to callous. Next, dip the leaves in rooting hormone and place them in a slightly moist succulent potting mix. Soon, a new rosette will grow from the base of the leaf. Once enough roots form, remove the old leaf and repot the rosette.
General Care
No pruning is necessary except to remove dead leaves. This helps prevent rot and bugs. Avoid touching the plant's healthy leaves, as your body oils will leave marks.
Whether grown outdoors or indoors, these plants are good to forget about. Too much attention from nervous gardeners will kill the plant. When grown outdoors in a wet environment, ensure the soil is sandy and well-draining. If you are not careful, your plant will turn into rotten mush. Indoors, a standard commercial succulent soil mix works well.
Pests and Problems
Mealybugs are one of the most common pests. Symptoms of a mealybug infestation include slowed or stopped growth (in summer, this is a normal sign of dormancy). If this occurs without apparent cause, remove the plant from the pot and examine the roots or the leaf-stem junctions. A white cottony substance is a sure sign of mealybug infestation. Remove all soil and gently wash the roots. Dab the cottony spots with a Q-tip dipped in rubbing alcohol. Remove any damaged roots with a sharp, sterile knife or scissors. Let them dry before replanting.
If you have an unhealthy plant, start by examining your watering habits. The most common problem is root rot due to overwatering.
