Germination
Cestrum diurnum follows a specific process for successful seed germination. To enhance germination, it's beneficial to scarify the seeds by gently rubbing them with sandpaper or nicking the seed coat with a knife. After scarification, soak the seeds in room temperature water for 24 hours to soften the seed coat and promote germination. Prepare a well-draining seed starting mix and sow the seeds at a depth of about 1/4 inch in individual containers or seed trays. Keep the soil consistently moist but not waterlogged, as excessive moisture can lead to rot. Place the containers in a warm location with temperatures around 70-80°F (21-27°C) to encourage germination, which typically occurs within 2-4 weeks. Once the seedlings emerge, provide them with bright, indirect light and gradually acclimate them to outdoor conditions before transplanting them into their permanent location. With careful attention to these steps, successful germination and healthy growth of Cestrum diurnum seeds can be achieved.
