How to propagate Painted-Leaf Begonia
Leaf cuttings: cut a healthy leaf in early summer. Starting at the base of the leaf and using the veins as a guide, cut the leaf into triangular sections, ensuring the central veins stay intact. Insert the tip of each section into compost, ensuring the main vein is in contact with the growing medium and the leaf is upright. Keep covered and place on a bright windowsill where the temperature remains between 16 to 27°C. Roots should appear within two months. Take softwood cuttings of about 10 cm and root in a glass of water.
Divide Begonia rhizomes in early spring just as the plant starts to put on more growth. Make sure each section has one or more growing points and replant straight away.
Sow seeds of species at 21C as soon as they are ripe.
