Dig the planting holes about 2 inches deeper than the height of the bulb. Space the planting holes 3 to 4 inches apart.
Place one bulb in each planting hole with the pointed end sticking straight up. Push the soil back around the bulb and cover it with 2 inches of soil. Press down gently with the flat of your hand. Continue until all the bulbs are planted.
Soak the area with water immediately after planting to settle the soil around the bulbs. Add enough water to dampen the soil to the bottom of the planting hole.
Spread a 4- to 6-inch layer of mulch over the planting area to keep the bulbs warm through the winter. The shoots will emerge in the spring and flower in the summer with little additional care.
Cut back the dead plant material when it turns brown and dies in the fall. Spread a 4- to 6-inch later of mulch over the bulbs for winter protection.
