To plant them west of the Cascade Mountains in the Pacific NW you will need to mix top soil (potting soil) 50 / 50 with a landscape sand and & small pea gravel mix. Have the root ball raised about 1/4 out of the hole but mounded up with the soil mixture. (Never use beach sand in the planting mix)Protect from high off shore winds if planting on the coast. Plant in an area that will get early morning and mid day sun during the winter months.I recommend using a water meter the first few years. They usually only need to be watered in the summer months and then only when young or after transplanting.
