Planting
How to Grow
- Select a large, open site with full sun and good drainage.
- Dig a hole two to three times wider than the root ball.
- Place the tree ensuring the root flare is at or slightly above soil level.
- Backfill with the original soil, breaking up any large clumps.
- Water thoroughly to settle the soil and eliminate air pockets.
- Apply a 3-inch layer of mulch, keeping it away from the trunk.
Pro Tip
Prune sparingly and properly when young to develop a strong structure, avoiding large cuts on mature trees which can invite disease.
