Buy Red Yucca seeds from a seed company. This ensures the plants will have predictable characteristics, particularly with regard to the color of the flowers.
Select a planting site in a desert environment with full sun. Red Yucca is hardy in U.S. Department of Agriculture hardiness zones 8 and higher, meaning it can tolerate temperatures as low as 10 degrees Fahrenheit.
Prepare a light soil mixture for Red Yucca. This plant grows well in sandy loam with a soil pH near neutral, ideally between 6.8 and 7.2. Add peat to the soil to lower its pH. Add limestone to the soil to raise its pH.
Fill a seed tray with the soil mixture. Place the Red Yucca seeds on the soil, separating them by 1 to 2 inches. Cover the seeds with 1/4 inch of soil and put the seed tray in full sun. Water Red Yucca seeds only when the soil is completely dry.
Transplant the Red Yucca seedlings to the permanent planting site when they are six inches tall. Dig holes with a garden trowel that are at least 3 inches deep and at least 4 feet apart. Place the seedlings in the holes and position them so that less than 1 inch of the stalk is below soil level and fill the hole with soil. Red Yucca plants should not require any maintenance from this point.
