Choosing the Right Grass for Your Lawn

Now that we have a good understanding of the different grasses suited for subtropical climates, it’s time to figure out which one is right for your lawn. 

Here are a few things to consider:

1. Soil Type of Your Lawn: Take a good look at your soil. Is it sandy, clayey, or loamy? Different grasses have different soil preferences. For instance, Bahia grass does well in sandy and less fertile soils, while Centipede grass prefers acidic soils.

2. Amount of Sunlight the Lawn Receives: The amount of sunlight your lawn receives is another critical factor. Bermuda grass, for example, loves full sun and would be an excellent choice for a sunny lawn. In contrast, Zoysia grass is more shade-tolerant and can be a good option for lawns with partial shade.

3. Expected Lawn Usage: How do you plan to use your lawn? Is it mainly for aesthetic purposes, or will it be subjected to heavy foot traffic from children or pets? Bermuda grass is highly resilient and can handle a lot of activity, making it a great choice for families. On the other hand, if your lawn is mainly for show, a grass type like Zoysia or St. Augustine, which creates a lush, beautiful turf, might be more appropriate.

Considering the above list can help you make a good decision on the best grass variety for you lawn, making sure it looks great and thrives under your specific conditions.

Maintenance Tips for Subtropical Lawns

Once you’ve selected the right grass for your lawn, proper care and maintenance are essential to keep it healthy and looking its best. 

Here are some tips specific to subtropical lawn care:

1. Watering Recommendations: Even though subtropical grasses are generally heat-tolerant, they still need adequate water, especially during the drier months. A good rule of thumb is to water your lawn deeply but infrequently, about one to one and a half inches of water per week. It’s better to water early in the morning to reduce evaporation.

2. Fertilization Needs and Schedule: Fertilizing your lawn provides necessary nutrients that might be lacking in the soil. Most subtropical grasses should be fertilized in late spring or early summer when they start actively growing. Be sure to choose a fertilizer that matches the specific needs of your grass and soil type.

3. Mowing Practices: Regular mowing helps to maintain a neat appearance and promotes denser growth. Each grass type has an ideal mowing height that should be maintained. Never remove more than one-third of the grass blade at a time to avoid stressing the grass.

4. Pest and Disease Control: Regular inspection of your lawn for signs of pests and disease can help catch any problems early before they cause significant damage. If you identify an issue, consult with a local extension service or a lawn care professional for advice on treatment.

Remember, every lawn is unique, and these guidelines may need to be adjusted based on your specific circumstances.

Common Challenges in Subtropical Lawn Care and Solutions

Taking care of a lawn in subtropical climates comes with its unique set of challenges. Here are some common issues you may encounter and practical solutions to overcome them:

1. Fungus and Disease: High humidity and heat can create a breeding ground for various lawn diseases and fungal infections. Regularly inspect your lawn for signs of disease, such as yellowing or wilting patches. Solutions include adjusting watering to avoid overly wet conditions, ensuring good drainage, or using fungicides.

2. Pests: Pests like chinch bugs, mole crickets, or grub worms can damage your lawn. Look out for irregular brown patches or areas where the grass seems loose at the roots. Pest control methods may include introducing beneficial insects, using pest-specific insecticides, or consulting with a lawn care professional.

3. Drought Stress: Despite being adapted for hot conditions, subtropical grasses can still suffer from drought stress during extended dry periods. Signs include a bluish-gray tint to the grass, wilting, or footprints that remain visible. To mitigate, water deeply but infrequently to encourage deep root growth, and consider mulching to conserve moisture.

4. Weed Control: Weeds can invade your lawn and compete with your grass for nutrients. Regular mowing can help prevent weeds from going to seed and spreading. In case of persistent weed problems, consider using a selective herbicide or hand-weeding.

5. Soil Compaction: Soil can become compacted over time, especially in high-traffic areas, making it hard for water and nutrients to reach the grass roots. If your lawn feels hard or water tends to pool on the surface, you may have compacted soil. Lawn aeration, which involves creating small holes in the soil, can help alleviate this problem.

By understanding these common challenges, you can better care for your lawn and keep it healthy and vibrant even in the challenging subtropical climate.


Taking care of a lawn in a subtropical climate can be both a rewarding and challenging endeavor. With the right grass selection tailored to your specific lawn conditions and diligent maintenance, it’s entirely possible to cultivate a lawn that not only survives but thrives in the subtropical climate.
