You need to know where not to plant crepe myrtle trees before you dig. Stay away from heavy shade, spots next to driveways, areas under power lines, and soggy ground. Each of these spots creates problems that will haunt you for years.
In my experience, the worst crepe myrtle planting mistakes involve shade. A street near my old office had trees on both sides. The south-facing yards had trees loaded with blooms and clean leaves. The north-facing yards told a sad story. Those trees grew leggy and thin with white mildew coating the leaves by July. Same street, same trees, totally different results.
Shade fails for clear technical reasons. Less sunlight means your leaves stay damp longer after rain. That wet air helps mildew spores spread fast across the foliage. Shaded trees also grow long, thin branches that reach for light. This stretched-out growth looks awkward and makes almost no flowers at the tips.
NC State Extension warns that crepe myrtle flowers stain walkways and car paint. This makes driveways and parking areas some of the worst spots for your tree. Colorful petals drop by the thousands during bloom season. They leave pink, red, or purple marks on concrete and car finishes. Keep your tree at least 15 feet from any surface you want to stay clean.
Soggy soil kills crepe myrtles faster than most other threats. These trees need well-drained ground to keep their roots healthy. Plant one in a low spot that holds water and the roots will rot within a season or two. You'll see leaves turning yellow and dropping early. Test drainage by digging a 12-inch hole and filling it with water. If water still sits there after an hour, that's a bad location for crepe myrtle.
Power lines and property edges are two more bad locations for crepe myrtle trees. A big variety under utility wires will get butchered by tree crews every few years. The Tree Center says to plant at least 3 to 5 feet inside your property line. This keeps branches from growing into your neighbor's yard and starting fights.
Check your spot before you dig. Count the sun hours, test the drainage, look up for wires, and measure the gap to driveways and property lines. Those five quick checks take ten minutes and save you from the most common mistakes people make with these trees.
