One of the best characteristics of the Bahiagrass is how it can effectively curb soil erosion. Combine that with its strong resistance to hot weather, and you’ve got a natural solution against roadside erosion.
However, not everyone is pleased with Bahiagrass, especially when it quickly invades their beloved lawns. It doesn’t help at all that this type of grass has an unpleasing appearance relative to evergreen lawns. With our assistance, you can quickly learn how to get rid of Bahiagrass.
To eradicate Bahiagrass, you must first know what it is exactly. One prominent feature to look for in identifying Bahiagrass is its seed head shaped like the letter Y. Still, awareness of this characteristic doesn't help that much in prevention and removal since the appearance of these Y-shaped seeds are also a sign that the grass is already at its invasive stage.
Thus, an alternative option is to look at the grass itself. The Bahiagrass is warm-season grass that has a light green color. It has a high heat tolerance, so it can survive even when there is no shade during hot summer days.
This grass can also combat drought due to its low-water and low-nutrient requirement. When you touch it, it will feel rough. Moreover, this grass is spread through rhizomes and forms clumps as it proliferates around a given area.
Here's a video talking about Bahiagrass identification:
There are two common types of Bahiagrass: the Pennington Pensacola Bahiagrass and the Pennington Argentine Bahiagrass. The former is characterized by its ability to thrive in drought-prone areas with poor soil conditions. The complex and sturdy root system allows it to tolerate not just hot weather but also the winter cold.
On the other hand, the Pennington Argentine Bahiagrass features a dark green appearance that's less coarse in texture than the common Bahiagrass. One can even say that this is a relatively good-looking grass despite being invasive. While it doesn't have significant tolerance to cold weather, it's a low-maintenance grass that isn't prone to plant disease.
If you want to remove Bahiagrass in your lawn, you can either dig it out or apply a potent herbicide. For the first option, you must first irrigate the areas affected by the Bahiagrass one day before the operation. Make sure that the water has reached at least 10 inches down the soil. This will allow you to unearth the roots quicker the following day thanks to wet soil.
Consequently, choosing to use herbicide will require you to check what kind of turfgrass you have in your lawn first. This is important because not every herbicide effective against Bahiagrass will be safe for other grass varieties. Unless you want to clear out other grasses, you must pay attention to the label of the herbicides.
For example, the Imazaquin herbicides are okay for lawns with St. Augustine grass, Zoysia, grass, and centipede grass, but it's not recommended for fescue grass. On the other hand, Atrazine herbicide is only safe for use on centipede grass and St. Augustine grass.
Regardless of the method you choose, you have to fill the spots emptied out of Bahiagrass with sprigs of the turfgrass you currently have. This will significantly reduce the chances of Bahiagrass appearing that area again.
If you want to clear out small sections of Bahiagrass located in your ornamental beds, you simply have to dig them out. Similar to Bahiagrass removal in the lawn, this can be efficiently done by adequately watering the soil a day before you remove them. While you can just use your hands, a spade can help you remove Bahiagrass with more precision.
However, simply digging out the Bahiagrass won't work if a huge portion of the ornamental bed has already been infested. In this case, you should get a non-selective glyphosate herbicide.
While this will also kill all other plants it reaches, this is the most effective way to deal with large Bahiagrass infestations. If you do want to save some of your plants, you can do so by covering them with plastic or surrounding them with cardboard. Once the area has been emptied out, you must fill it with at least three inches of mulch.
Since Bahiagrass thrives under the sun, you can prevent its quick spread by giving it an abundance of shade. Likewise, its capacity to grow in poor soil conditions means that it will suffer when it's grown in soil rich with nitrogen.
Another good prevention method is to cleanse your lawn mower before and after operations deeply. You can't ever be sure that your machine didn't come into contact with Bahiagrass while it was working on your lawn, so watering it after use is a must.
Lastly, applying the right amount of fertilizer and water to your sod will make it healthy enough to detract Bahiagrass and other types of wild grass.
In conclusion, removal of Bahiagrass will require you to know its characteristics that make it so invasive. While simply digging it out can work for small-scale Bahiagrass invasions, you are better off using the appropriate herbicide to get rid of large Bahiagrass infestations.
