Care

Plant this in very well draining soil and keep it in a spot with intense sun. Watch for shriveled stems as a sign it needs a deep soak, but be careful not to overwater during its dormant phase. It is perfectly adapted to harsh, dry conditions.

Watering
Water deeply only during the active growing season when the soil is completely dry.
Feeding
Use a low nitrogen, cactus specific fertilizer sparingly during the spring.
Pruning
Only remove dead or damaged stems during the late winter before new growth begins.
Repotting
Repot only when the plant has clearly outgrown its container, using a heavy pot to prevent tipping.

Signs it needs repotting

  • Roots growing out of the drainage holes.
  • Water sitting on the surface for too long.
  • Plant becoming top heavy.

    Growing it

    Propagation
    cuttings, seed
    When to plant
    spring, early autumn
    Overwintering
    Keep the plant dry during winter months to prevent rot. Ensure it is protected from extreme, prolonged freezing temperatures.
    In containers
    It can be grown in a large, heavy pot with excellent drainage, but it prefers being in the ground.

    Cuttings

    1. Take a hardwood cutting during the dormant season.
    2. Allow the cut end to callus for several weeks in a dry, shaded area.
    3. Insert the callused end into a well draining, sandy potting mix.
    4. Keep the soil barely moist until roots establish.

    Group with other desert natives that require minimal irrigation to prevent accidental overwatering.
