While able to withstand most soil types, this Crape Myrtle prefers slightly acidic, well-drained soil. If you decide to fertilize your tree, opt for a multi-purpose, slow-release fertilizer and apply once early in the spring. A common myth is that heavy fertilizing will increase the abundance of blooms. However, giving your tree too much fertilizer will support foliage growth, at the expense of your blooms. When it comes to the Crape Myrtle, less is more.
