Angel wing begonia or Begonia coccinea is a cane type begonia with succulent leaves and stems. This begonia grows upright with large wing shaped leaves. Periodically, clusters of small flowers appear on short stems. The blooms are white, pink or red. Propagation is through stem cuttings, which is a way to grow a plant that is the same as the parent plant. These propagated plants are called clones.
Wash a 6-inch plant pot with hot soapy water. Rinse the pot with a mixture of 1 part bleach and 9 parts water. This will get rid of any plant disease or hiding pests.
Mix equal parts of sand, peat moss and potting soil. This makes a lightweight potting soil that drains well. Fill your plant pot within 1 inch of the rim with your soil mixture.
Cut 4 to 6 inches off the end of a stem with a clean, sharp knife. Using a sharp knife minimizes the damage done to the cutting. A dull blade can crush the plant tissue.
Dip the cut end into the rooting powder. Place the stem cutting 2 inches into the soil in the plant pot. Spray the soil thoroughly with water. Place your plant pot in a warm area with indirect light.
Keep the angel wing begonia cutting moist by misting it with the spray bottle. Occasionally check for roots by gently tugging on the cutting. If it resists your pull, then it has formed enough roots to be transplanted into a larger pot.
