The "Oft Quoted" and Timeless Advice of Rick Hobson:
1. Dig a hole at least twice as wide, but just as deep as root ball.
2. Mix garden compost and peat into the soil in a proportion of between 1/3 and 1/2.
3. Set plant into hole and back fill with prepared soil.
4. Soak the plant thoroughly with water and then water every day for two weeks. Continue to water as the plant grows and don’t forget to water in winter. Use root stimulator weekly.
5. Cover with cypress or cedar mulch to help retain water.
Tip: Use the left over soil (the part that was not mixed with compost or peat) and make a berm around the plant the same diameter as the hole, to retain water. Leave it in place for a year, preferably longer!
