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.

Leaf pruning:

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.

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.
