1. Origins and Overview


The Black Diamond Crape Myrtle (Lagerstroemia indica x fauriei ‘Black Diamond’) is a hybrid variety developed by Plant Introductions Inc. and marketed by J. Berry Nursery.

The breeders aimed to create a plant with intense flower colouration and unique foliage, and they succeeded brilliantly.

The Black Diamond Crape Myrtle thrives in full sun, requiring at least six hours of direct sunlight per day. It is adaptable to various soil types but prefers well-draining soil.

4.2 Watering and Fertilisation

Regular watering is essential during the tree’s establishment period, but once established, it becomes relatively drought tolerant. However, for the best performance and abundant blooms, it is recommended to provide regular water during dry spells. Applying a layer of organic mulch around the base of the tree helps retain moisture and regulate soil temperature.

Fertilising the Black Diamond Crape Myrtle is beneficial for promoting healthy growth and vibrant blooms. Use a balanced, slow-release fertiliser in early spring, following the manufacturer’s instructions. Avoid excessive fertilisation, as it can lead to excessive foliage growth at the expense of flower production.

4.3 Pruning and Maintenance

Pruning the Black Diamond Crape Myrtle is essential for maintaining its shape, encouraging new growth, and promoting abundant flowering. It is best to prune during late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches. To encourage a more compact and bushier form, selectively prune the outer branches. Avoid excessive pruning, as it can reduce flowering potential.

Regular inspections for pests and diseases are crucial to maintain the health of your Black Diamond Crape Myrtle. Common pests include aphids, scale insects, and powdery mildew. If infestations occur, treat them promptly using organic or chemical remedies.
