Weigela plants are popular ornamental shrubs that are loved for their beautiful flowers and lush foliage. But, these plants can also attract a variety of pests, including slaters. Slaters, also known as woodlice or pillbugs, are small crustaceans that feed on decaying plant matter and can cause damage to the leaves and stems of weigela plants. Fortunately, there are several effective ways to get rid of slaters on weigela plants.
Before you can get rid of slaters on your weigela plant, it’s important to identify the problem. Slaters are small, oval-shaped insects that are usually gray or brown in color. They have seven pairs of legs and can roll themselves up into a ball when threatened. If you notice holes in the leaves or stems of your weigela plant, or if you see slaters crawling around on the plant or in the soil, you likely have a problem with these pests.
One of the easiest ways to get rid of slaters on your weigela plant is to remove any infested leaves and stems. Use a pair of clean scissors or pruning shears to cut off any damaged or diseased parts of the plant. Be sure to dispose of these parts in a sealed bag or container to prevent the slaters from spreading.
Slaters thrive in moist environments, so keeping the soil around your weigela plant dry can help deter these pests. Make sure your plant is located in an area with good drainage and avoid overwatering. If your weigela plant is in a pot, be sure to empty any excess water from the saucer underneath the pot.
Diatomaceous earth is a natural substance that can be used to kill slaters on your weigela plant. This powdery substance is made from the fossilized remains of tiny aquatic organisms and is harmless to humans and pets. Sprinkle a thin layer of diatomaceous earth around the base of your weigela plant or directly on the soil surface.
Insecticidal soap is a safe and effective way to get rid of slaters on your weigela plant. This soap is made from natural ingredients and works by suffocating the pests. Mix one tablespoon of insecticidal soap with one quart of water and spray the solution directly onto the leaves and stems of your weigela plant. Be sure to cover all surfaces thoroughly and repeat the treatment every few days as needed.
Creating a physical barrier around your weigela plant can also help keep slaters at bay. You can use a variety of materials to create a barrier, including copper tape, petroleum jelly, or sticky traps. Apply the material directly to the soil surface around the base of your weigela plant or wrap it around the stem.
