Scaling Back: How To Treat Crape Myrtles With Bark Scale
It’s the time of year when we field many questions about why crape myrtles are turning black. Here’s why and how to easily fix it.
There’s a bug that’s making it’s way around our region attacking Crape Myrtles. It’s called Crape Myrtle Scale and it attacks by secreting an enzyme (yes that means poop!) all over the crape myrtle, which then molds over turning your crape myrtle black. Yuck!
This many bugs produces a large amount of honeydew (a euphemism for bug poop) that sticks to the branches. This results in a build-up of black colored sooty mold on the leaves and trunks of the infested plants along with anything growing under the tree.
There is a treatment that is easily applied each spring to prevent Scale from turning beautiful Crape Myrtles into ugly, black eyesores. It is a systemic drench that is poured around the base of the tree. The drench is absorbed through the roots and distributed throughout the tree that protects it from Scale for a year. No messy spraying is necessary.
Follow the directions on the label to find the amount needed for the size of your tree, mix it with water and pour around the base of the tree.
Here’s a hint on how to determine the correct amount to use for multi-trunk trees. Measure the circumference (distance around the trunk) of the main trunks at 5 feet from the ground – about chest high. Add the circumferences together, this is the number you will use in determining how much of the systemic to use.
Don’t let Scale prevent you from enjoying summer long blooms from such beautiful trees.
