The seeds have a hard seed coat that has to be treated, or scarified, in order for water to enter the seeds so that they can sprout. 1. Scarify the seeds by nicking or sanding the seed coat. The seeds can be sanded with sandpaper, a nail file or an emery board. 2. Soak the seed in water for 24 hours. 3. The seeds like moist, well-drained soil. Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Put the soil in a pot. Water the mixture so that it is moist but not wet. 4. Put the seeds on the soil. 5. Cover the seeds with a layer of soil about 1 inch thick. 6. Water the seeds. 7. Place the pots in an area with warm temperatures in full sun or part shade. 8. When the seedlings are a few inches tall, they can be transplanted.
