Taxonomic Information

Appearance

Lagerstroemia Indica has a smooth, mottled bark that peels off in patches to reveal a cinnamon-brown color. Its leaves are dark green, glossy, and oval-shaped, with pointed tips and serrated edges. In the fall, the leaves turn a vibrant shade of orange, red, or yellow. The tree produces clusters of crinkled, crepe-like flowers that are about 1 inch in diameter. The flowers grow in terminal panicles and vary in color depending on the cultivar. The tree’s fruit is a small, dry capsule that splits open to release numerous tiny seeds.

Care Guide

Lagerstroemia Indica is relatively easy to grow and care for. Here are some essential tips:

• Water: Water the tree deeply and regularly, especially during the first few years of growth. Once established, the tree can tolerate some drought.
• Fertilization: Fertilize the tree in the spring with a balanced, slow-release fertilizer. Avoid over-fertilizing, as it can lead to excessive vegetative growth and fewer flowers.
• Soil: The tree prefers well-draining soil that is slightly acidic. Amend the soil with organic matter, such as compost or peat moss, to improve its texture and fertility.
• Sunlight: Lagerstroemia Indica thrives in full sun but can also tolerate partial shade. Ensure that the tree receives at least six hours of direct sunlight each day.
• Hardiness Zones: The tree is hardy in USDA zones 7 to 9, although some cultivars can tolerate colder temperatures.

Common Pests & Diseases

Lagerstroemia Indica is relatively resistant to pests and diseases. However, here are some common issues that you may encounter:

• Aphids: These small, soft-bodied insects feed on the tree’s sap and excrete a sticky substance called honeydew, which attracts ants and can lead to the growth of sooty mold. Control aphids by spraying the tree with a strong jet of water or applying insecticidal soap.
• Powdery Mildew: A fungal disease that causes a white, powdery coating on the leaves and stems. It thrives in humid conditions and can weaken the tree if left untreated. Control powdery mildew by improving air circulation around the tree and applying fungicides.
• Cercospora Leaf Spot: A fungal disease that causes circular, reddish-brown spots on the leaves. It can defoliate the tree if left untreated. Control cercospora leaf spot by removing infected leaves and applying fungicides.

Habitat

Lagerstroemia Indica is native to China, Korea, and India and grows in a variety of habitats, including forests, scrublands, and open fields. It prefers well-draining soil and full sun but can also tolerate partial shade. The tree is widely cultivated in different parts of the world, including the United States, where it is used as an ornamental tree in gardens, parks, and landscapes.
