Seed Starting Indoors
Seed starting indoors can be done two to three weeks ahead of the expected planting date. This method allows for better control of the plant's growing conditions, including temperature, light, and moisture levels. The seeds should be sown in seed-starting trays filled with moist seed starting mix. The tray should be covered with plastic wrap or a dome to retain moisture and placed in an area that receives plenty of light. The seedlings should be kept moist, and once they have developed their second set of leaves, they can be transplanted outdoors.
Overall, Navarretia mellita is an easy-to-grow and hardy plant, which makes propagation straightforward. Whether propagated through direct sowing or seed starting indoors, successful propagation can result in a beautiful display of blue, purple, or white flowers.
