Care

Let the soil dry out completely between waterings to prevent root rot. Watch for shriveled leaves which indicate the plant needs more water, while mushy stems suggest overwatering. Ensure the pot has drainage holes to keep the roots happy.

Watering
Water only when the soil is completely dry throughout the pot.
Feeding
Feed with a balanced liquid fertilizer during the active growing season.
Pruning
Trim back long stems in spring to encourage a bushier shape.
Repotting
Move to a slightly larger pot only when the plant becomes root bound.

Growing it

Propagation
cuttings, leaf cuttings
When to plant
spring, early summer
Overwintering
Move indoors before the first frost. Keep in a bright spot and reduce watering significantly during the winter months.
In containers
They are excellent in containers, provided the pot has drainage holes and is filled with a fast draining succulent mix.

Stem Cuttings

  1. 1. Snip a healthy stem.
  2. 2. Let the cut end callous for two days.
  3. 3. Place in dry succulent soil.
  4. 4. Wait a week before watering.

Group succulents with similar water needs together to prevent accidental overwatering of the drought tolerant ones.

Grows well with

  • Echeveria · They share similar light and water requirements.
  • Aloe · Both plants thrive in the same well draining soil conditions.

Similar species

  • Sedum · These are also succulent plants that enjoy similar growing conditions.

Where the name comes from

The name Crassula refers to the thick, succulent leaves characteristic of the genus.

Good to know
