Propagating Dudleya Brittonii

Taking Cuttings

• Take cuttings from giant chalk dudleya in spring when the plant shows vibrant, active growth. Like most succulents that grow in rosette form, dudleya develops small offsets, or pups, at the base of the plant. To propagate dudleya, remove one of the pups. Sever the pup as close to the parent plant as possible, as the pup needs a stem where roots can form. Before severing the pup from the parent plant, sterilize the knife by wiping it with rubbing alcohol or a solution of one part bleach and 10 parts water.

Preparing the Container

• Succulents require a porous, well-draining potting mixture to prevent rot. Fill a 3-inch pot about two-thirds full, using two parts of a commercial potting soil for cacti and succulents mixed with one part coarse sand. Fill the pot to about 1/2 inch from the rim, using a thick layer of coarse sand or fine gravel, which allows moisture to evaporate. Water the mixture until it is barely moist.

Preparing the Pup

• To prepare the pup for planting, set it aside in a warm, dry place until the cut edge forms a firm callus -- usually at least 48 hours. The callus helps to prevent moisture from entering the stem and causing rot. You can dip the callused stem in a liquid, powdered or gel hormone to speed rooting. Additionally, you can dust the callus with powdered sulfur to help prevent disease. However, neither is critical.

Planting

• Plant the cutting by inserting the stem through the gritty top covering and into the potting mix below. The leaves should be slightly above the soil. Dudleya roots best in warmth and bright, indirect light. If you have a heating mat, set it at 70 degrees Fahrenheit. Otherwise, keep the bottom of the pot warm on top of a refrigerator or other warm appliance. Do not cover the pot with plastic, because succulents require constant ventilation to prevent rot. Water only enough to keep the potting mix from becoming bone dry. Rooting, evidenced by the appearance of new growth, usually occurs within two to four weeks.
