Step-by-Step Guide

The first step in managing bark scale involves cleaning the tree to remove honeydew and black sooty mold.

1. Prepare a solution of water and soap, using several tablespoons of soap for every two gallons of water.
2. Using a soft bristle brush, scrub the trunk of the tree, focusing on getting the soapy water into the cracks and crevices.

Before applying insecticide, accurately measure the height of the crapemyrtle.

1. Estimate the height of the tree by comparing it to a person standing next to it, or use a measuring stick.
2. Record the height to the nearest foot.

Choose an appropriate systemic insecticide for treating the bark scale.

1. Read the product label carefully to ensure it is suitable for use on your tree.
2. Calculate the amount of insecticide needed based on the tree's height, using three ounces per foot of height.
3. Mix the calculated amount of insecticide with enough water to saturate the soil around the base of the tree.

Apply the insecticide solution around the base of the tree to ensure effective absorption.

1. Evenly distribute the insecticide mixture around the tree base, avoiding the drip line.
2. Avoid application after heavy rainfall to ensure soil absorption is maximized.

Pro Tips

Utilizing effective strategies can enhance your pest management efforts.

1. Always apply insecticide when the tree is not in bloom to minimize harm to pollinators.
2. Monitor your trees regularly for signs of bark scale to catch infestations early.
