Fertilization is an important aspect of caring for Acoma Crape Myrtle. The tree should be fertilized in early spring, just before the growing season begins. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is recommended. The fertilizer should be applied around the base of the tree, with care taken to avoid getting it on the foliage or trunk. For young trees, use about 1/4 pound of fertilizer per year of age, up to a maximum of 4 pounds. For mature trees, use 1/2 to 1 pound of fertilizer per inch of trunk diameter, up to a maximum of 8 pounds. It's important not to over-fertilize Acoma Crape Myrtle as it can lead to excessive growth, weak branches, and reduced flower production. Hence, the fertilization should be done as per the guidelines given above.
