10 seeds Planting rhododendrons from seed involves sowing them in a nutrient-poor, acidic soil mix and then carefully repotting them several times before they are large enough to be planted out in the garden. The process is slow and results vary, but success requires giving the plants the right conditions in terms of moisture, light and soil. Prepare the planting soil: Use a loose, well-drained, acidic soil, such as a mixture of peat and sand. • Sow the seeds: Sprinkle the seeds thinly on the surface of the soil in a shallow pot or tray. Cover with a very thin layer of soil or vermiculite, but not too deep - rhododendron seeds need light to germinate. • Water gently: Lightly mist the surface of the soil so that it is evenly moist, but not wet. • Create a humid environment: Cover the pot with plastic wrap or place it in a plastic bag to retain moisture and warmth. • Place in a bright and cool place: Place the pot in a bright place but avoid direct sunlight, and preferably at a temperature of around 15-20 degrees. • Be patient: The seeds can take several weeks to months to germinate. • When the plants have several leaves: Replant them into small pots with acidic soil and continue to care for them carefully.
