How to Get Rid of Slaters on Cordyline Glauca Plant

Cordyline glauca, also known as the Ti Plant or Hawaiian Good Luck Plant, is a popular ornamental plant that is commonly grown for its colorful leaves and attractive appearance. However, one common problem that many gardeners face is the presence of slaters or pillbugs on their Cordyline glauca plants. These pests can cause damage to the leaves and stems of the plant if left unchecked. In this article, we will discuss some effective ways to get rid of slaters on Cordyline glauca plants.

What are Slaters?

Slaters, also known as pillbugs or woodlice, are small crustaceans that are commonly found in gardens and other outdoor areas. They have a hard exoskeleton and are usually grey or brown in color. Slaters feed on decaying plant matter and can sometimes damage living plants if their numbers become too high.

Signs of Slater Infestation

If you notice slaters crawling around your Cordyline glauca plant, it is likely that there is an infestation. Signs of a slater infestation include:

• Small holes in the leaves
• Damaged stems or roots
• Presence of slaters around the base of the plant

How to Get Rid of Slaters on Cordyline Glauca Plant

Here are some effective ways to get rid of slaters on Cordyline glauca plants:

1. Remove Decaying Plant Matter

Slaters feed on decaying plant matter, so removing any dead leaves or other debris from around your Cordyline glauca plant can help reduce their numbers. Use a pair of pruning shears to cut away any dead or damaged leaves, and rake up any fallen debris from around the base of the plant.

2. Use Diatomaceous Earth

Diatomaceous earth is a natural powder that is made from the fossilized remains of diatoms, a type of algae. It is an effective insecticide that can help kill slaters on contact. Sprinkle a thin layer of diatomaceous earth around your Cordyline glauca plant, being careful not to get any on the leaves or stems.

3. Apply Insecticidal Soap

Insecticidal soap is a safe and effective way to control slater infestations on Cordyline glauca plants. This soap works by breaking down the outer protective layer of the slater’s exoskeleton, causing them to dehydrate and die. Follow the instructions on the label carefully when applying insecticidal soap, and be sure to avoid getting any on the leaves or stems of your plant.

4. Use Nematodes

Nematodes are microscopic worms that are harmless to humans but can be deadly to slaters and other garden pests. You can purchase nematodes at most garden centers or online. Simply mix them with water according to the instructions on the package and spray them around your Cordyline glauca plant.

5. Create a Barrier

Another effective way to keep slaters away from your Cordyline glauca plant is to create a physical barrier around it. You can do this by placing a ring of copper tape or mesh around the base of the plant, or by wrapping the stem in a strip of sticky tape. Slaters are repelled by copper and will avoid crossing it.
