Care and Propagation Information

General Care for Haworthia coarctata

Haworthia coarctata is a perfect addition to a rock garden. It adds excellent “filler” to a succulent arrangement. Watch for green flowers in the summer.

Watering

Haworthia coarctata has typical watering needs for a succulent. It’s best to use the “soak and dry” method, and allow the soil to dry out completely between waterings.

Where to Plant

Haworthia coarctata is not cold hardy, so if you live in a zone that gets colder than .0° F (-1.1° C), it’s best to plant this succulent in a container that can be brought indoors. It does well in full to partial sun. Plant in an area of your garden that gets 6 hours of sunlight a day.

Echeveria purpusorum

Commonly Mistaken For

Haworthia reinwardtii. Haworthia coarctata’s leaves are smaller, wider, and smoother than those of Haworthia reinwardtii.

How to Propagate Haworthia coarctata

Haworthia coarctata is a prolific propagator, growing many offsets. It can also be propagated by seeds and leaves.

Offsets

Haworthia coarctata will produce small offsets, sprouting up around the base of the plant. Simply pull these up and allow the offsets to dry for one to two days before replanting.

Leaves

You can propagate the leaves of Haworthia coarctata by choosing a firm, healthy leaf. Remove it from the main plant by gently twisting the leaf from the stem. Be sure not to leave any of the leaf on the stem (if you take a bit of the stem with the leaf, that’s fine, too!).

Allow the leaf to callous over for several days, and then lay on well-draining soil. Water whenever the soil has dried completely. After roots and a rosette have appeared, and the mother leaf has withered away, plant the new growth.

Seeds

If propagating from seed, sow in a well-draining soil in the fall. You can grow Haworthia seeds outdoors if you live in a zone above 9a. If you live in a cooler area, you can begin sowing indoors under a grow light.
