Planting Acoma Crape Myrtle
Successful growth of Acoma crape myrtle begins with proper planting. Follow these guidelines to ensure your plants get off to a great start.
When to Plant
The best time to plant Acoma crape myrtle is in early spring or fall. These cooler periods allow the roots to establish before the onset of extreme summer heat or winter cold.
Site Selection
Acoma crape myrtle thrives in full sun, requiring at least 6-8 hours of direct sunlight each day. Choose a location that provides ample sunlight and has well-drained soil. Avoid low-lying areas where water tends to pool.
Soil Preparation
While Acoma crape myrtle is adaptable to a range of soil types, it performs best in slightly acidic to neutral soil (pH 5.5 to 7.0). Improve soil fertility and drainage by incorporating organic matter, such as compost or well-rotted manure, into the planting site.
Planting Steps
- Dig the Hole: Dig a hole twice as wide and as deep as the root ball.
- Prepare the Plant: Remove the plant from its container and gently loosen the roots.
- Place the Plant: Position the crape myrtle in the hole so that the top of the root ball is level with the surrounding soil.
- Backfill: Fill the hole with the excavated soil, gently firming it around the roots.
- Watering: Water thoroughly to settle the soil and eliminate air pockets.
- Mulching: Apply a 2-3 inch layer of mulch around the base of the plant to retain moisture and suppress weeds.
Caring for Acoma Crape Myrtle
Proper care ensures that your Acoma crape myrtle remains healthy and vibrant. Here are the key aspects of crape myrtle care:
Watering
Water newly planted crape myrtles regularly during the first growing season to establish a deep, extensive root system. Once established, they are drought-tolerant but will benefit from regular watering during prolonged dry periods.
Fertilizing
Crape myrtles are not heavy feeders, but a balanced, slow-release fertilizer applied in early spring can promote healthy growth and abundant blooms. Avoid high-nitrogen fertilizers, as they can encourage excessive foliage growth at the expense of flowers.
Pruning
Pruning is essential for maintaining the shape, promoting vigorous growth, and enhancing flowering.
- When to Prune: The best time to prune Acoma crape myrtle is in late winter or early spring before new growth begins.
- How to Prune: Remove any dead, damaged, or diseased branches. Thin out overcrowded branches to improve air circulation. Lightly shape the plant as desired. Avoid excessive pruning, as it can reduce flowering.
Mulching
Mulching helps retain moisture, regulate soil temperature, and suppress weeds. Reapply mulch each spring and fall, keeping it a few inches away from the plant's stems to prevent rot.
Pest and Disease Control
Acoma crape myrtle is generally resistant to pests and diseases, but occasional problems may arise.
- Aphids: These small insects can be controlled with insecticidal soap or a strong stream of water.
- Scale Insects: Treat with horticultural oil.
- Powdery Mildew: Although Acoma crape myrtle is resistant, ensure good air circulation and avoid overhead watering to prevent this fungal disease.
