How to Propagate Hardy Begonias

The hardy begonia is native to China and grows best in partial shade. This plant has very attractive, heart-shaped leaves that are burgundy-colored on the undersides. Blooming in mid- to late summer until frost, the flowers are dainty and either pink or white. Hardy begonia produce small bulbils in the leaf axil (where the leaf attaches to the main stem) when the flowers bloom, at the end of summer. These can be gathered when they drop from the plant and potted up to create new plants. Other propagation methods include root division, layering and stem cuttings, which is the easiest method. Take the stem cutting in the spring.

Instructions

things you’ll need:

• Scissors
• Small planting pot with holes in the bottom for drainage
• Compost
• Peat moss
• Water
• Rooting hormone

1. Cut 3 to 6 inches of stem from the hardy begonia plant, cutting at an angle.
2. Fill the planting pot with equal parts of compost and peat moss, to within 1/2 inch of the top. Water the soil well, allowing the excess water to drain from the bottom of the pot.
3. Remove flowers and buds and any leaves on the lower third of the stem.
4. Dip the end of the stem into the rooting hormone, tapping it on the side of the jar to remove any excess powder or liquid.
5. Using your finger or a pencil, create a 2-inch hole in the planting mix and insert the hormone-tipped end of the stem into the soil.
6. Place the potted cutting in a shady, warm area and keep the soil moist, not soggy.
7. Repot the hardy begonia when the roots are well-established. Use the next-largest pot size from the one in which the hardy begonia is currently growing.
