How to Grow Chionanthus retusus in the Garden
When choosing a location for Chionanthus retusus, it is best to opt for a spot that receives full sun to part shade.

Planting is best done in early spring or fall, when the tree is dormant. Dig a hole twice as wide and about as deep as the root ball, next place the tree in the hole, and then backfill with soil. Water thoroughly after planting.
Regular watering is crucial during the first growing season to establish a strong root system.
Once it has become established, then Chinese Fringe Trees are moderately drought-tolerant, but will appreciate a watering during prolonged dry periods. Feed with a general-purpose fertilizer in early spring, before the new growth begins.
Pruning is not normally typically necessary, as Chionanthus retusus naturally grows into an attractive, rounded shape. However, if you desire to prune for size or shape, do so following blooming.
Be on the watch for pests such as scales and borers, and fungal diseases like powdery mildew or leaf spots. Generally, maintaining healthy growing conditions can prevent most of these problems.
Growing Chionanthus retusus into your garden can introduce an element of soft elegance to its setting. With the right conditions, this tree will reward you with a stunning display of fluffy, white blooms year after year.
