|Only ripe seed is capable to germinate well. Indoors you can sow by the beginning of December under additional lights. The medium used for germination can be similar to media recommended for Rhododendron. A mixture of sand and peat covered with sphagnum that is cut into short pieces. The seeds should be sown on the surface of the mix and not covered. They need light and will not germinate in the dark. A moist medium and high humidity are necessary for germination. The best temperature for germination and initial growth is between 70 and 75 °F (21 and 24 °C). Most seeds will germinate in 10 to 20 days.|
