Steps for Planting King
- Place it outside in a shady spot and increase its exposure
slowly by an hour a day over several weeks time. Once it is acclimated
to full sun plant it in the chosen spot.
- Dig a hole twice as wide as the root ball. Note: The hole
should be as deep as the root ball is tall. The soil
surrounding the roots should be loose to allow for easy establishment.
