Gardeners who have a small landscape may still enjoy the benefit of fresh citrus by planting a Dwarf Washington navel orange tree (Citrus sinensis "Dwarf Washington Navel"). These Brazilian natives reach a mature height of only 8 feet and produce sweet oranges that are suitable for fresh eating or juicing. Hardy in U.S. Department of Agriculture plant hardiness zones 9 through 11, "Dwarf Washington Navel" trees grow best in full sunlight and deep, fast-draining, sandy soils. Soak seeds overnight. Some people plant the seed immediately in a potting soil and small peat pot. Others remove the seed coat, the wrinkly white coat on the seed, and then soak it overnight and plant it. This process rushes the germination time. You can also put the seed between layers of damp towel and put it into a plastic bag until it sprouts, and then plant it. Wait for the sprouts to appear. If there are three sprouts, the center one is normally weak. Remove it by snipping it off. Keep the pot's soil moist by either covering it with a plastic drape or keeping it in a plastic bag until you notice the sprouts emerging.
