How To Care
Be sure you choose the right location and conditions for your new Black Diamond Purely Purple Crape Myrtle to thrive. Crape Myrtles are easy to grow and don't require much maintenance. You can plant your crape myrtle just about any time of year. Avoiding temperature extremes is ideal, of course. Black Diamond Crape Myrtles grow in zones 7-10.
These trees prefer full sun, but can tolerate mild shade and are adaptable to just about any soil as long as it is well-draining. Crape Myrtles do enjoy a slightly acidic soil with a pH range of 5.0 or 6.5 being ideal, but as long as your soil isn't extremely alkaline there is no need to modify it. Mulching with a 2-3 inch layer of pine straw or pine bark is ideal for crape myrtles. Do not allow the mulch to touch the trunk as these increases the chances of pests and disease. Mulching helps keep soil moist and protects roots during temperature extremes. Crape Myrtles should be watered deeply about 2 times per week after planting for about 3 months. After this establishment period, water deeply about once weekly when conditions are dry. Crape Myrtles are drought tolerant once established. Fertilize in early spring and when planting with our balanced, slow release fertilizer to give your tree a boost and help it achieve the best blooms Crape Myrtles do not generally require pruning, but if needed, prune when they are dormant to remove any dead, dying, or crowded branches. Avoid the need to over prune your tree by choosing a variety that fits best in your chosen spot. You can choose a variety that is only 5 feet tall up to varieties that grow over 30 feet tall. Black Diamond Crape Myrtles grow up to 12 feet tall and about 8 feet wide.
The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. Black Diamond Crape Myrtles rarely have issues with pests and are disease resistant. Aphids are one of the few pests that attack crape myrtles. Minor infections aren't likely to cause problems, but a severe infection can weaken your tree. You can treat aphids naturally with horticultural oil, neem oil, or insecticidal soap. For severe infections use pesticides like carbaryl, also known as Sevin. Black Diamond Crape varieties are extremely resistant to Powdery Mildew.
