Dig a hole three to four times as wide and the same depth as the rootball. Do not disturb soil at bottom of the hole. Fill planting hole with water and allow to drain. Fill again. Water should drain in about 24 hours. If it hasn't, try another site, create a drainage chimney, or consider a raised bed. Remove plant from container; slice the outside of the rootball if rootbound. Set in planting hole with top of rootball one inch above the surrounding soil level. Fill hole with soil dug from the planting hole; no need to add amendments. Water thoroughly to settle soil. Build a soil basin or install sufficient drip emitters. Add 3 to 4 inches of mulch over the root area to conserve moisture.
