109.4 Cultivation Notes
109.4.1 Potting & Root Pruning
Schedule: spring.
Notes: limit root pruning. They dislike having their roots disturbed. At the same time they tolerate cramped roots.
109.4.1.1 Top & Branch Management
Heavy pruning: prune in early spring before new growth starts. When the shrub is young, it can be trained into a tree form by choosing the largest and strongest stem (or stems if you’d prefer a multi-trunk tree) and pruning all other stems to ground level.

109.4.2 Feeding
Wax myrtles generally do not require very much fertilizing. Avoid using an excessive amount of nitrogen.
109.4.3 Pests & Problems
No serious insect or disease problems. Leaf browning typically occurs in cold winters.
109.4.4 Winter Storage
Mulch thoroughly. We are at the northern boundary of the USDA hardiness zone for wax myrtle, so trees will need extra protection.

109.7.1 Natural History
Native from New Jersey west to eastern Oklahoma and east Texas, south through Mexico to Central America as well as through much of the Caribbean.
A wispy, 6-12 ft., multi-trunked, evergreen shrub, southern bayberry or wax myrtle can reach 20 ft. in height. The light olive-green foliage has a spicy fragrance. Pale blue berries occur on female plants in the winter. Handsome gray bark is almost white on some plants.
