If you are a homeowner in Houston with St. Augustine grass, you may be wondering how to keep your lawn healthy and weed-free. One solution is to use a weed and feed product specifically designed for St. Augustine grass in the Houston area. But before you rush to the store, it's important to do your research to ensure you choose the right product for your lawn.

Here are five key points to keep in mind when looking for weed and feed for St. Augustine grass in Houston:

1. Choose a product specifically formulated for St. Augustine grass. Not all weed and feed products are suitable for this type of grass, so make sure to read the label carefully.

2. Look for a product that targets the weeds commonly found in Houston lawns, such as dandelion, clover, and crabgrass.

3. Check the nitrogen content. St. Augustine grass requires a high level of nitrogen to thrive, but too much can damage the lawn. Aim for a product with around 20% nitrogen.

4. Consider the timing. It's best to apply weed and feed in the spring or fall, when the grass is actively growing. Avoid applying during a drought or heatwave, as this can also damage the lawn.

5. Follow the instructions carefully. Applying too much or too little can be ineffective or even harmful to your lawn. Be sure to apply at the recommended rate and water the lawn thoroughly after application.

By keeping these key points in mind, you can find the right weed and feed product for your St. Augustine grass and keep your lawn healthy and free of weeds.
