CARE - Plant in a hole that is 2 times larger than the size of the root ball, making sure to break apart some of the root ball prior to planting if it looks root bound (essentially if the root ball is firm and stiff with roots). Water deeply every few days for the first couple of months after planting, or as needed when leaves start to wilt. Should not require any watering after the first year. You can also use to high quality compost to speed some of the growth in lower nutrient areas. Prune to achieve the desired height and spread.
