Controlling centipede grass can be a bit challenging as it is a warm-season grass that can aggressively spread and take over lawns. To effectively kill centipede grass, the best approach is to use a weed control product that contains glyphosate. Glyphosate is a broad-spectrum herbicide that is commonly found in products like Round-Up.
Before applying any herbicide, it is crucial to carefully read and follow the instructions provided by the manufacturer. Make sure to wear appropriate protective gear, such as gloves and eye protection, and avoid spraying on windy days to prevent the herbicide from drifting onto desirable plants.
Here are the steps to effectively control centipede grass with glyphosate:
1. Timing: The best time to apply glyphosate for centipede grass control is during its active growth phase, typically in late spring or early summer. This ensures that the grass is actively taking in the herbicide for maximum effectiveness.
2. Mowing: Prior to applying glyphosate, mow the centipede grass to a height of about 1-2 inches. This helps expose more of the grass blades and allows better herbicide absorption.
3. Spot treatment: If you have small patches of centipede grass, spot-treating with glyphosate can be an effective approach. Use a handheld sprayer or a paintbrush to carefully apply the herbicide only to the centipede grass, avoiding contact with desirable grasses or plants.
4. Broadcast application: For larger areas infested with centipede grass, a broadcast application of glyphosate is recommended. Dilute the herbicide according to the manufacturer’s instructions and apply evenly over the affected area using a sprayer or a watering can.
5. Wait and reapply if necessary: After applying glyphosate, wait for the recommended amount of time specified on the product label before mowing or reseeding the treated area. Keep in mind that glyphosate is a non-selective herbicide and will kill any vegetation it comes into contact with. If any centipede grass regrows or new sprouts emerge, you may need to reapply the herbicide for complete eradication.
It’s important to note that glyphosate is a systemic herbicide, meaning it is absorbed by the plant and moves throughout its system, effectively killing the entire plant, including the roots. However, it can also affect desirable grasses and plants if not applied carefully. Take precautions to avoid spray drift and follow the label instructions to minimize any potential damage to surrounding vegetation.
Remember that controlling centipede grass may require multiple applications and ongoing maintenance to prevent its reestablishment. Regularly monitoring your lawn and promptly treating any new growth or infestations can help keep centipede grass in check.
Please note that while this method can be effective, it is always recommended to consult with a local lawn care professional or extension office for specific recommendations tailored to your region and lawn conditions.
