Dynamite Crape Myrtle Trees
Dynamite Crape Myrtle is a stunning multi-stemmed flowering tree known for its vibrant red flowers, which make it a standout in any landscape. This variety of Crape Myrtle, scientifically known as Lagerstroemia indica 'Dynamite,' is prized for its long-lasting blooms that last from early summer through the fall, providing a continuous splash of color. The fiery red flowers are complemented by dark green leaves that turn a striking orange-red in the fall, adding to its seasonal appeal. Perfect for creating visual impact, Dynamite Crape Myrtles are often used in rows for driveway borders or as an eye-catching focal point in large garden spaces.
The Dynamite Crape Myrtle is not only beautiful but also highly adaptable and drought-resistant once established, making it an excellent choice for gardeners looking for low-maintenance yet dramatic landscaping options. It thrives in full sun, requiring at least six hours of direct sunlight daily to develop its best flower color and density. This plant is hardy in USDA zones 6 through 9, allowing it to be grown in various climates. Regular watering during its first growing season will help establish a deep, extensive root system. After establishment, it becomes increasingly drought tolerant, only needing extra water during exceptionally dry periods.
In addition to its ornamental features, the Dynamite Crape Myrtle is also highly resistant to powdery mildew, which can be a common issue in less resistant crape myrtle varieties. This characteristic ensures that its leaves and blooms remain attractive throughout the growing season. Pruning in late winter or early spring can help maintain its shape and promote a more vigorous bloom. When pruning, focus on removing any dead or crossing branches to enhance air circulation and light penetration throughout the canopy. With proper care and management, Dynamite Crape Myrtle will continue to be a durable and captivating addition to any landscape.

How to Care for Dynamite Crape Myrtle
Once you buy a Dynamite Crape Myrtle Tree, make sure to read about the care instructions that are recommended to keep this plant healthy and thriving.
How do I plant Dynamite Crape Myrtles?
To plant your Dynamite Crape Myrtles, start by selecting a location that receives full sun for at least six hours a day to ensure vigorous growth and vibrant red blooms. Dig a hole that is twice as wide and the same depth as the root ball, loosening the surrounding soil to help roots establish quickly. Position the tree so that the top of the root ball is level with the surrounding ground, then backfill with a mix of native soil and compost to improve drainage and nutrient availability. Water thoroughly after planting to eliminate air pockets, and apply a 2–3 inch layer of mulch around the base, keeping it a few inches from the trunk to prevent rot. When planting Dynamite Crape Myrtles, allow sufficient space for their mature size—typically 15 to 20 feet tall and 10 to 15 feet wide. This fast-growing variety is perfect for creating bold privacy screens, colorful focal points, or flowering allees in larger landscapes. If planting multiple trees, space them at least 8 to 10 feet apart to allow for full canopy development and good airflow. Water regularly during the first growing season to establish a strong root system, especially in hot or dry weather. With proper placement and early care, Dynamite Crape Myrtles will reward you with explosive red blooms and exceptional landscape performance year after year.
How do I water my Dynamite Crape Myrtle?
To water your Dynamite Crape Myrtle properly, focus on deep, infrequent soakings rather than light, frequent watering. During the first growing season, water thoroughly once or twice a week to keep the root zone consistently moist but not soggy. Deep watering encourages strong root development, which is essential for long-term drought tolerance and vigorous blooming. Always water at the base of the tree to prevent wetting the foliage, which can help reduce the risk of fungal diseases and promote healthier growth. Once established, Dynamite Crape Myrtles become highly drought tolerant and typically require minimal supplemental watering except during prolonged dry spells. To help maintain soil moisture and reduce evaporation, apply a 2–3 inch layer of mulch around the base, taking care to keep it away from the trunk. Check the soil moisture about 2–3 inches below the surface—if it feels dry, it's time to water. Proper watering not only supports lush foliage and brilliant red blooms but also ensures your Dynamite Crape Myrtle remains strong, healthy, and vibrant throughout the growing season.
How should I fertilize a Dynamite Crape Myrtle Tree?
To fertilize your Dynamite Crape Myrtle tree, apply a balanced, slow-release fertilizer such as 10-10-10 or 12-4-8 in early spring as new growth begins to emerge. Spread the fertilizer evenly around the tree’s drip line—avoiding direct contact with the trunk—and water thoroughly to help nutrients reach the root zone. This feeding promotes strong branching, lush foliage, and vibrant red flower production throughout the summer. Be cautious with high-nitrogen fertilizers, as they can encourage excessive leafy growth at the expense of blooms. For ongoing health and color performance, you can apply a light second feeding in midsummer if the soil is nutrient-poor or if flowering begins to slow. Alternatively, enriching the soil annually with compost or well-rotted manure can naturally improve fertility and soil structure. Always follow the manufacturer’s guidelines on application rates to prevent overfeeding. With consistent and correctly timed fertilization, your Dynamite Crape Myrtle will deliver explosive color, vigorous growth, and season-long ornamental impact in your landscape.
How and when should I prune my Dynamite Crape Myrtles?
You should prune your Dynamite Crape Myrtles in late winter or early spring, just before new growth starts to emerge. This timing ensures you won’t remove any developing flower buds, as Dynamite blooms on new wood. Begin by removing any dead, damaged, or crossing branches to encourage healthy airflow and a strong branch structure. Lightly thin out the interior of the canopy to increase sunlight penetration and reduce the risk of disease. Avoid the common mistake of severe topping—often called “crape murder”—which weakens the tree and reduces bloom production. When pruning Dynamite Crape Myrtles, aim to maintain their natural vase-like shape, which promotes upright growth and showcases their bold red flowers. Trim suckers from the base and remove small lateral branches that clutter the tree's structure. During the summer, you can also deadhead spent blooms to encourage a second round of flowering. With proper, well-timed pruning, your Dynamite Crape Myrtles will thrive with a strong form, vibrant foliage, and an extended season of show-stopping red blooms, making them a standout feature in any sunny landscape.
