Weed Killer for Zoysia Grass: What You Need to Know

Zoysia grass is a popular choice for those who want a lush green lawn. However, just like any other type of grass, it is susceptible to weed growth. Weeds can take away nutrients from the grass, leaving it unhealthy and unattractive. Luckily, weed killers can help solve this problem. In this guide, you'll learn everything you need to know about choosing the best weed killer for Zoysia grass.

Understanding Your Options

There are two types of weed killers: pre-emergent and post-emergent. Pre-emergent weed killers prevent weeds from growing in the first place, while post-emergent weed killers kill weeds that have already grown. Each type has its own benefits and drawbacks.

Pre-Emergent Weed Killers

Pre-emergent weed killers are typically applied before the weeds have a chance to grow. They work by preventing weed seeds from germinating, effectively stopping weed growth in its tracks. One of the main benefits of using pre-emergent weed killers is that they are selective, meaning they only target specific types of weeds. This makes them an ideal option for Zoysia grass, as they won't harm the grass itself.

How to Apply Pre-Emergent Weed Killers

When applying pre-emergent weed killers, timing is critical. You should apply them before the weeds have a chance to germinate. Typically, this means applying them in the early spring or late fall, depending on your location. You'll also need to water the area after application to ensure the weed killer is properly absorbed.

Post-Emergent Weed Killers

Post-emergent weed killers are applied after the weeds have already grown. They work by killing the weeds at their roots, preventing them from growing back. One of the benefits of using post-emergent weed killers is that they work quickly, often killing weeds within a few days.

How to Apply Post-Emergent Weed Killers

When applying post-emergent weed killers, it's important to use caution. These types of weed killers can be harmful to Zoysia grass if not applied correctly. Be sure to read and follow the instructions carefully. You should also avoid applying them during hot weather or when the grass is stressed.

Factors to Consider When Choosing a Weed Killer for Zoysia Grass

Choosing the right weed killer for your Zoysia grass requires careful consideration. Here are some factors you should keep in mind:

Type of Weeds

The type of weeds you're dealing with will play a big role in determining which weed killer is best for you. Some weed killers are more effective against certain types of weeds than others. For example, broadleaf weed killers are effective against dandelions and clover, while crabgrass killers are better suited for crabgrass.

Formulation

Weed killers come in various formulations, such as liquid, granular, and concentrate. Each formulation has its own benefits and drawbacks. Liquid weed killers are easy to apply, but they can be messy. Granular weed killers are less messy, but they can be harder to apply evenly. Concentrated weed killers require mixing, which can be time-consuming.

Safety

Safety should always be a top priority when using weed killers. Look for products that are safe for Zoysia grass and won't harm other plants or animals in your yard. You should also wear protective clothing, such as gloves and goggles, when applying weed killers.

Price

Weed killers come in a wide range of prices. While it may be tempting to choose the cheapest option, keep in mind that quality often comes at a price. Investing in a high-quality weed killer can save you money in the long run by effectively preventing weed growth.
