Explore the Complete Bahiagrass Lawn Maintenance Guide: Tips, Calendar, and Care

Bahiagrass is a warm-season grass commonly used in lawns due to its low maintenance requirements and ability to withstand drought and heat. This grass variety is native to South America and has become popular in many parts of the United States. In this comprehensive guide, we will explore the characteristics of Bahiagrass and the benefits of having a Bahiagrass lawn. We will also provide you with a detailed Bahiagrass lawn maintenance calendar.

What is the Bahiagrass?

Bahiagrass (pronounced buh-HEE-uh, buh-HI-uh, or buh-HEY-uh) is a warm-season grass well-suited for the Gulf Coast and Southeastern United States. It is commonly used as a pasture grass but has gained popularity as a lawn grass in the region. Bahiagrass has several desirable characteristics, including its ability to thrive in sandy and infertile soils and its high drought resistance. However, it is essential to note that Bahiagrass is unsuitable for high-traffic areas and does not produce a dense grass carpet.

Characteristics of Bahiagrass

Bahiagrass is known for its deep roots, which enable it to access water and nutrients from the soil. This characteristic makes Bahiagrass highly tolerant to drought conditions, making it an ideal choice for regions with limited rainfall. Additionally, Bahiagrass has a unique growth pattern, with tall seed heads that give the lawn a distinct appearance.

A critical characteristic of Bahiagrass is its ability to tolerate poor soil conditions. It can thrive in sandy or clay soils unsuitable for other grass varieties. However, Bahiagrass performs poorly in shaded areas and prefers total sun exposure. Understanding these characteristics will help you make informed decisions regarding Bahiagrass lawn maintenance.

How to Care for Bahiagrass

Your bahiagrass lawn will remain healthy, lush, and green throughout the growing season. Here are some essential maintenance tips:

Mowing Bahiagrass

Mowing is an essential aspect of maintaining a bahiagrass lawn. Regular mowing keeps the grass healthy and prevents the seed heads from becoming unsightly.

Mowing Height

The recommended mowing height for Bahiagrass is 3-4 inches. This height helps the grass maintain its health and withstand drought conditions.

Mowing Frequency

Plan to mow Bahiagrass every week to two weeks during the growing season. In the peak of summer, more frequent mowing may be required to keep the seed heads at bay. Bahiagrass has Y-shaped seed heads, a defining characteristic of this grass. While the seedheads may be annoying, they provide free overseeding for your lawn. It’s important to note that not all bahiagrass seeds will germinate in the same season, as some may remain dormant.

Sharpening Mower Blades

Bahiagrass seed heads and stems are tough on mower blades. To ensure a nice, sharp cut on your lawn, it’s essential to sharpen the blades frequently.


Regular edging along sidewalks, driveways, and flower beds gives your Bahiagrass lawn a clean and manicured appearance. Use a half-moon edger or a string trimmer for precise edging.

Watering Bahiagrass

Bahiagrass is known for its drought resistance and ability to survive in sandy and infertile soils. While it can withstand long periods without water, it will go dormant and turn brown. When rain returns, the grass will green up again and resume its growth. If you have the option to rinse, it’s essential to monitor the lawn for signs of drought stress, such as folded leaves, a change in color, and footprints that stay on the grass.

Watering and irrigation guidelines for Bahiagrass lawns

Proper watering is essential for the health and vitality of your Bahiagrass lawn. Follow these instructions to water your lawn efficiently:

  • Watering depth: Bahiagrass has deep roots, so it is crucial to water deeply to encourage root growth. Provide approximately 1 inch of water weekly, either through rainfall or irrigation.
  • Watering frequency: Water your Bahiagrass lawn once or twice a week, depending on the weather conditions. Watering deeply and infrequently is superior to watering shallowly and frequently.
  • Timing: Water your Bahiagrass lawn early to minimize evaporation and allow the grass to dry before evening. Avoid watering at night, as this can promote the growth of diseases.
  • Rainfall monitoring: Monitor the weather forecast and adjust your watering schedule accordingly. If there is sufficient rainfall, reduce or skip irrigation to prevent overwatering.

Following these watering and irrigation guidelines ensures that your Bahiagrass lawn receives the right amount of moisture for optimal growth and health.

Fertilizing Bahiagrass

Fertilization requirements for Bahiagrass vary depending on factors such as soil type, organic matter levels, and previous lawn care practices. It is essential to conduct a soil test before fertilizing to determine the specific needs of your lawn.

Fertilizer Application: Bahiagrass’s recommended nitrogen application rate is 1-4 pounds per 1,000 square feet per year, depending on your location. It’s important to check local guidelines for fertilizer blackout dates or ordinances. Applying fertilizer evenly and at the correct rate is crucial to avoid nutrient imbalances and potential damage to the grass.

Fertilization and weed control for Bahiagrass lawns

Proper fertilization and weed control are essential for maintaining a healthy and vibrant Bahiagrass lawn. Here are some guidelines to help you with these tasks:

  • Fertilization: Bahiagrass lawns benefit from regular fertilization to provide essential nutrients. Apply a slow-release nitrogen fertilizer in early spring and again in late summer or early fall.
  • Weed control: Bahiagrass has good natural weed resistance, but occasional invasions may occur. Use a pre-emergent herbicide during the early spring to hinder the germination of weed seeds. Spot-treat any existing weeds with a selective herbicide.
  • Mowing height: Maintaining the recommended mowing height of 3-4 inches helps shade the soil, preventing weed growth. Regular mowing also helps to control weeds by removing their seed heads.
  • Overseeding: If your Bahiagrass lawn develops thin or bare spots, overseeding can help fill in the gaps and improve the overall appearance. Choose a Bahiagrass seed variety compatible with your existing lawn.

By following these fertilization and weed control guidelines, you can keep your Bahiagrass lawn healthy and free from unsightly weeds.


Dethatching involves removing the thick layer of organic matter that accumulates on your lawn. While Bahiagrass typically does not form excessive thatch, it’s worth considering if you notice signs that your lawn needs dethatching after two or three years. It is best to dethatch warm-season grasses like Bahiagrass in late spring or early summer when they are actively growing.


Aeration is essential for relieving compacted soil, allowing nutrients, water, and oxygen to reach the grassroots. Compacted soil hinders turfgrass growth and may cause yellowing. You can check if your soil is compacted by using the screwdriver test. If pushing a screwdriver into the lawn is difficult, it’s likely that the soil is compacted and requires aeration. The best time to aerate warm-season grass, such as Bahiagrass, is in summer.

Dealing with Insects and Weeds

While Bahiagrass is relatively resistant to insects and weeds, monitoring the lawn and taking appropriate action when necessary is essential.


Mole crickets, bahiagrass billbugs, and fall armyworms are insects that may cause problems in bahiagrass lawns. Identifying the insect and taking appropriate measures, such as natural or chemical treatments, can help control infestations.


Maintaining a healthy lawn is the best defense against weeds. Regular mowing at the proper height, irrigation when needed, and appropriate fertilization can help prevent excessive weed growth. If weeds persist, it’s essential to identify the specific types and choose the proper treatment. Overseeding the lawn with bahiagrass seed annually can help fill gaps and discourage weed growth.

Soil pH

Bahiagrass may turn yellow in high-pH soil, which indicates iron deficiency. To combat this problem, add soluble iron sources like ferrous ammonium sulfate, ferrous sulfate, or iron chelates to your soil.

Common Diseases

While Bahiagrass is generally resistant to pests and diseases, specific issues may arise. Here are solutions to common problems.

  • Chinch bugs: Chinch bugs are small insects that feed on grass blades, causing yellow or brown patches. Treat chinch bug infestations with an appropriate insecticide labeled for use on Bahiagrass.
  • Armyworms: Armyworms are caterpillars that can quickly defoliate a Bahiagrass lawn. Apply a suitable insecticide if armyworms are detected.
  • Dollar spot fungus: Dollar spot is a common fungal disease characterized by small, round patches on the lawn. Apply a fungicide labeled for use on Bahiagrass to control dollar spot.
  • Brown patch fungus: Brown patch is another fungal disease affecting Bahiagrass lawns. Apply a fungicide and adjust watering practices to prevent the spread of this disease.

If you encounter pests or diseases in your Bahiagrass lawn, consult a professional like EcoLawn Utah or your local extension office for proper identification and treatment recommendations.


Bahiagrass does not naturally produce a dense turf carpet. If you want to encourage growth and improve the appearance of your lawn, consider overseeding annually. Overseeding helps make the turf thicker, reduces weed growth, and repairs unsightly damage. The best time to overseed Bahiagrass with warm-season grass seeds is in late spring or early summer. In the fall, you can also incorporate cool-season ryegrass to prolong the green duration throughout the winter.

Over time, Bahiagrass lawns may develop thin or bare spots that require overseeding or renovation. Here are some steps to follow for successful overseeding:

  • Preparation: Before overseeding, mow your existing Bahiagrass lawn to a height of 1-2 inches. Remove debris and loosen the topsoil with a rake or a core aerator.
  • Seed selection: Choose a Bahiagrass seed variety that matches your existing lawn. Consult with a local nursery or extension office for recommended seed varieties.
  • Seeding: Broadcast the Bahiagrass seed evenly over the prepared area, following the recommended seeding rate. Use a rake to incorporate the seeds into the soil lightly.
  • Watering: Keep the seeded area consistently moist until the new grass has been established. To avoid soil drying, water lightly and regularly.

If your Bahiagrass lawn requires more extensive renovation, you may need to consider completely removing the existing grass and starting from scratch. Consult a lawn care professional like EcoLawn Utah for guidance on the best approach for your situation.
