The Savannah holly (Ilex x attenuata 'Savannah') is an evergreen tree or shrub that grows naturally in a pyramid shape. Used for privacy screening or as a garden ornamental, the Savannah holly offers white flowers for spring interest and bright red berries in the fall and winter. Savannah reaches 18 feet tall with a 10-foot spread when grown within its U.S. Department of Agriculture Hardiness zones 6 through 9. Savannah is a versatile holly that can tolerate sandy or clay soil, wet or dry conditions and requires little pruning.
Cut out all dead and damaged branches. Make the cut 1/2 inch above a leaf, at a 45-degree angle.
Force the Savannah holly branches to grow in the desired direction by cutting them back to a bud that is facing in that direction. For instance, to make the holly branch grow upward, cut the branches just above an upward-facing bud.
Paint large pruning wounds with an asphalt-based wound dressing. Arborists with the U.S. Department of Agriculture suggest that this will keep boring insects out of the wood. Follow the instructions on the dressing's label and do not over-apply.
