Growing From SeedsThe seeds can be germinated and seedlings planted at any time but the seeds will need to be scarificed first to break open the seed coat and allow water to germinate the seed (see techniques below). If you already have a flame tree, harvest the long, strappy dark brown seed pods when they fall to the ground in the spring.Remove the seeds from the pod.Soften the coating of the seeds by soaking them in warm water for a day or two before planting in potting mix.Scarify the softened seeds by gently nicking or scratching each one with a knife; this process allows water in and speeds up the germination process. Some gardeners suggest rubbing the seed with sandpaper for a few seconds to generate peeling.Add well-draining potting mix to a 3- to 6-inch deep seed tray. Place each seed 1 inch deep and 3 inches apart. Pat the soil firm around each seed.Put the tray in a warm, partially shaded outdoor area. Keep the soil moist but not overwatered. Seeds begin to germinate in four to six days.Transplant 8-inch high seedlings to a 1-gallon container. Continue transplanting your seedlings as they grow until you are ready to select a site in your landscape to root the tree.Growing
