Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the plant from the container, gently tease the roots.
Position in hole and backfill with soil, gently firming down. Form a raised or doughnut shaped ring of soil around the outer edge of the plant's root zone. This helps keep water where it's needed. Always water in well after planting to settle the soil around the roots and keep the soil moist for several weeks while the new plant establishes.
Mulch around the base with organic mulch like sugarcane or woodchip, keeping it away from the trunk.
