Dig the planting hole twice as wide and to the same depth as the root-ball.
If planting in winter, soak bare-rooted plants in a bucket of water for 30 minutes prior to planting. Remove from bucket, position in hole and backfill with soil, gently firming down. If planting a potted plant, remove the shrub from the container, gently tease the roots and cut away any circled or tangled roots, then position in hole and backfill.
Mulch around the base with organic mulch like bark chips, sugarcane or pea straw, keeping it away from the trunk.
Water deeply, once every 2-3 days, depending on weather conditions. Once established, water deeply once every week.
