    Growing it

    Propagation
    cuttings, division
    When to plant
    spring, summer
    Overwintering
    Bring the plant indoors before the first frost. Reduce watering significantly during the winter months to allow for a dormant period.
    In containers
    It is excellent for hanging baskets or shallow pots that allow the stems to trail gracefully.

    Stem cuttings

    1. 1. Snip a 5 to 10 cm stem segment.
    2. 2. Remove the lowest pearls to expose the stem.
    3. 3. Lay the stem on top of moist, well draining soil.
    4. 4. Keep the soil lightly damp until roots form.

    Group plants with identical water needs to prevent accidental overwatering of your succulent.
