How to Get Rid of Slaters on Shiso Plant

Introduction

If you have a shiso plant in your garden, you may have encountered slaters, also known as pill bugs or woodlice. These small crustaceans are common pests that can damage your shiso plant by eating its leaves and stems. Fortunately, there are several effective methods to get rid of slaters and protect your shiso plant. In this article, we will discuss these methods in detail so you can keep your shiso plant healthy and thriving.

Understanding Slaters

Before diving into the various methods to eliminate slaters from your shiso plant, it is essential to understand their behavior and characteristics. Slaters are small, segmented arthropods that belong to the order Isopoda. They have a roundish body shape with seven pairs of legs and are typically gray or brown in color.

Slaters are nocturnal creatures that thrive in damp environments. They prefer to live in dark, moist areas such as under rocks, logs, or decaying vegetation. However, they can also infest plants, including shiso plants, if conditions are favorable.

Methods to Get Rid of Slaters on Shiso Plant

1. Remove Attractants

The first step in controlling slaters on your shiso plant is to remove any potential attractants from your garden. Slaters are drawn to moisture and decaying organic matter, so make sure to clean up any fallen leaves or debris around your shiso plant. Regularly inspect the area for any decaying vegetation and remove it promptly.

2. Improve Drainage

Since slaters thrive in damp conditions, it is crucial to improve the drainage around your shiso plant. Ensure that the soil is well-drained and not overly watered. Avoid overwatering your shiso plant, as this can create a moist environment that attracts slaters. If necessary, amend the soil with organic matter or perlite to improve drainage.

3. Provide Proper Air Circulation

Slaters prefer stagnant air, so providing proper air circulation around your shiso plant can help deter them. Trim any dense foliage or overcrowded plants that may obstruct airflow. Additionally, consider spacing your shiso plants adequately to allow air to circulate freely.

4. Use Organic Pest Control Methods

Several organic pest control methods can be effective in eliminating slaters from your shiso plant:

• Diatomaceous Earth: Sprinkle food-grade diatomaceous earth around the base of your shiso plant. The sharp particles in diatomaceous earth will pierce the slaters’ exoskeleton, causing them to dehydrate and die.

• Beer Traps: Fill a shallow container with beer and bury it up to its rim near your shiso plant. Slaters are attracted to the smell of beer and will crawl into the container, where they will drown. Check and empty the traps regularly.

• Citrus Peels: Place citrus peels, such as lemon or orange peels, around your shiso plant. Slaters dislike the smell of citrus and will avoid areas where these peels are present.

• Beneficial Predators: Introduce natural predators such as ground beetles or centipedes into your garden. These predators feed on slaters and can help control their population.

5. Natural Repellents

Certain natural substances can act as repellents and deter slaters from infesting your shiso plant:

• Copper Tape: Wrap copper tape around the base of your shiso plant. Slaters dislike the sensation of copper on their bodies and will avoid crossing it.

• Crushed Eggshells: Crushed eggshells can create a barrier around your shiso plant that slaters find difficult to crawl over. Scatter crushed eggshells around the base of the plant to deter them.

• Garlic Spray: Create a garlic spray by blending garlic cloves with water and straining the mixture. Spray this solution around your shiso plant to repel slaters.

6. Chemical Control

If the infestation is severe and other methods have failed, you may consider using chemical control methods. However, it is important to use these methods as a last resort and follow the instructions provided by the manufacturer. Choose an insecticide specifically labeled for slaters and apply it according to the recommended dosage. Be cautious when using chemicals and ensure they are safe for use on edible plants like shiso.

Conclusion

Slaters can be a nuisance when they infest your shiso plant, but with the right approach, you can effectively control and eliminate them. By removing attractants, improving drainage, providing proper air circulation, and utilizing organic pest control methods or natural repellents, you can keep your shiso plant healthy and free from slaters. Remember to choose the most suitable method for your situation and always prioritize organic and environmentally friendly solutions. With persistence and care, you can enjoy a thriving shiso plant without the presence of unwanted slaters.
