Bahia grass is a perennial grass that is commonly found in warm-season areas. While it is a useful forage grass, it can be a nuisance when it invades lawns, garden beds, and other areas where it is not wanted.
The best way to control bahiagrass depends on the type of lawn or garden bed you have, the time of year, and the extent of the infestation. In this article, we will discuss the most effective methods for bahiagrass control, including both chemical and organic approaches.

Understanding Bahia Grass
Before we dive into the methods for controlling bahiagrass, it’s important to understand the plant itself. Bahiagrass is a coarse grass that has a light green color and grows in clumps or tufts. It spreads through rhizomes and seeds, and can quickly take over an area if left unchecked.
Bahiagrass has a high tolerance for drought and can survive in hard-packed soils, making it a common sight on roadsides and vacant lots.
One of the most unappealing features of bahiagrass is its y-shaped seed heads, which can make lawns and garden beds look unkempt. Additionally, bahiagrass can compete with other plants for water and nutrients, making it difficult to maintain a healthy garden or lawn.
Chemical Control of Bahiagrass
Chemical control of bahiagrass rests on the use of herbicides. There are numerous chemicals available for bahiagrass control, including pre-emergent and post-emergent herbicides. Pre-emergent herbicides are used to prevent bahiagrass seeds from germinating, while post-emergent herbicides are used to kill existing bahiagrass plants.
When using herbicides, it’s important to follow the product’s instructions carefully. Some herbicides require multiple applications or specific timing to be effective. Additionally, some herbicides may harm other plants in the area, so it’s important to be selective in their use.
Glyphosate is one of the most effective herbicides for bahiagrass control. It is a non-selective herbicide that kills all plants it comes into contact with, so it should be used with caution. Glyphosate is best applied in the early spring or fall, when the bahiagrass is actively growing.
Organic Control of Bahiagrass
If you prefer an organic approach to bahiagrass control, there are several methods you can use. The first step is to prevent bahiagrass from spreading by constant vigilance and care of weed seeds. This means consistently mowing your lawn, removing any bahiagrass shoots that appear, and using preventative measures such as organic mulch or layers of wet newspaper to smother any seeds that may be present.
Another useful bahiagrass preventer is white vinegar. Vinegar solutions can be sprayed directly onto bahiagrass plants, causing them to wither and die. However, vinegar can also harm other plants in the area, so it should be used with caution.
Proper watering techniques can also help control bahiagrass. Bahiagrass thrives in dry conditions, so consistent lawn mowing and watering can help prevent its growth. Additionally, using an organic fertilizer on your lawn or garden beds can help promote the growth of other plants, which can outcompete bahiagrass.
Bahiagrass Control in Different Settings
The best way to control bahiagrass depends on the setting in which it is growing.
Bahiagrass in Lawns
- Consistent lawn mowing is the first line of defense against bahiagrass in lawns. Mowing your lawn at the correct height and frequency can help prevent bahiagrass from taking over.
- Annual fertilization can also help promote the growth of other turf grasses, which can outcompete bahiagrass.
- Post-emergent herbicides can be used to kill existing bahiagrass plants, but they may also harm other plants in the lawn.
Bahiagrass in Garden Beds
- Organic mulch can be used to smother any bahiagrass seeds that may be present in garden beds.
- Consistent weeding and removal of any bahiagrass shoots can help prevent its spread.
- Selecting plants that are well-suited to the area and have an open canopy can help prevent bahiagrass from taking over.
Bahiagrass in Pastures
- Bahiagrass is a useful forage grass, but it can quickly take over pastures if left unchecked.
- Selecting other forage grasses that are well-suited to the area can help prevent bahiagrass from taking over.
- Post-emergent herbicides can be used to kill existing bahiagrass plants, but they may also harm other plants in the pasture.
Bahiagrass on Roadsides
- Bahiagrass is a common sight on roadsides, where it can help with erosion control.
- Consistent mowing and use of post-emergent herbicides can help control bahiagrass on roadsides.
- Selecting other plants that are well-suited to the area and have an open canopy can help prevent bahiagrass from taking over.
Conclusion
Controlling bahiagrass can be a constant battle, but with the right efforts, it can be managed. Whether you prefer a chemical or organic approach, vigilance and consistency are key. By following the tips outlined in this article, you can keep bahiagrass from taking over your lawn, garden beds, or pastures.
