How Do You Kill Weeds In Bahia Grass

Bahia grass, commonly known as highway grass, belongs to the types of warm-season grasses, and the grass is highly aggressive. Bahia grass’s characteristic “Y-shaped” seed head makes Bahia grass identification easy.

It can grow in various soil conditions and spread via seeds and rhizomes. The mat-forming Bahia grass has a light green color, coarse texture, and an open canopy. It is native to South America and was brought to the United States in 1913 as fodder grass in Florida.

The aggressive nature of Bahia grass, and its drought tolerance, make it suitable for erosion control along highways and roadsides. However, because the seed heads spread quickly, its aggressive nature makes it difficult to control, and on occasions, it is classed as a weed by the way it spreads.

Tips in Killing Bahia Grass

Before beginning a weed control program, homeowners should understand that totally eliminate Bahia grass isn’t a workable solution.

However, it is better to control the onset of weeds to a tolerable level. Bahia has a fairly open habit and is prone to many broadleaf weeds.

Thus, controlling weeds in Bahia lawns can be an extreme challenge.

In our guide, you can learn more about a weed killer for Bahia grass, as not all are suitable, or not all will work without killing the grass.

By the end, you’ll see which Bahia grass herbicide may suffice or is it better for you to hand-pull weeds from your home lawns instead.

What Is Bahia Grass?

Bahia grass is a warm-season grass that can withstand heat and drought.

Brought initially from Brazil – South America, as a roadside and pasture grass in the early twentieth century, Bahia grass thrived in Florida’s blistering heat and sandy soils because of its self-seeding, low-growing, low-maintenance turf features.

Many homeowners in the southern United States use a modern Bahia grass cultivar as a lawn grass.

Because few insects attack Bahia grass, insecticide treatments are limited. In addition, because of its ability to swiftly recover from drought, homeowners without an irrigation system or in areas with water restrictions frequently choose Bahia grass over other warm-season turf species.

However, it is an aggressive perennial grass that can infest lawns. Not every homeowner wants a Bahia lawn. Once bahia grass has established itself, complete eradication is unlikely. A bahia weed killer or atrazine products should completely remove it if it’s undesired.

Common Cultivars of Bahia grass

Common Bahia grass:

Crops with coarse-textured light-colored blades grow in irregular clusters. Close cuts reveal bare soil between grass areas.

It tolerates mild grazing well. Older pastures may contain common Bahia grass, although modern cultivars have mostly replaced it.

Argentine Bahia grass:

This cultivar produces a dense turf with dark green blades, making it an appealing lawn covering.

A well-established lawn usually weeds out. It has deep roots that withstand drought. The Argentine kind is relatively free of insects.

Pensacola Bahia grass:

Pensacola turf has longer and narrower leaf blades than Argentine. It can also withstand colder temperatures than Argentine.

But it yields more seed heads than the Argentine. Not suitable as a lawn turf, but ideal as a pasture grass.

Tifton-9 Bahia grass:

A fine-blade Bahia grass with exceptional cold tolerance. It spreads seeds swiftly and grows quickly.

Because of its high fodder content, it is commonly used in northern regions to control erosion along roads and pastures.

How To Control Bahia Grass

Ways to Control Bahia Grass

Weed Control in Lawns

Maintaining your lawn’s health and density is best to avoid weeds. Weeds can be controlled by mowing height, irrigation, and fertilization. (Learn How To Get Rid Of Dollar Weeds In Flower Beds)

If Bahia grass invades a turf area, it can be dug up or treated with an herbicide. If an herbicide is used, it should be applied at the right time.

Using post-emergent herbicides to control Bahia grass is vital because it is a perennial weed with rhizomes. Therefore, post-emergent herbicide applications should begin in May when Bahia grass is actively growing.

After removing Bahia grass weeds from the turf, bare spots will remain. Fill up these bare spots with plugs or sprigs of the preferred turf grass to prevent weed invasion.

Glyphosate: Spot treatments with a non-selective herbicide, like glyphosate, can control weeds and kill attractive grasses. Multiple applications will be required to control Bahia grass.

Vegetable Garden Control

To treat weeds before tilling a vegetable garden is best. Tilling can disperse weed seed and perennial grass rhizomes throughout the garden plot.

Hand pulling, mulch, and post-emergent herbicides are some ways used to control weeds in the vegetable garden.

For small garden plots, hand-pulling Bahia grass may be practical.

Hand pulling is best done while the soil is damp so that the Bahia grassroots may be easily removed.

Organic mulch such as pine needles, crushed leaves, compost, or grass clippings can help limit Bahia grass growth in the garden.

Apply 6-8 moist newspaper sheets as a weed barrier before applying mulch. The newspaper layer prevents weed growth by restricting light to the weeds underneath, and the newspaper should decay by spring.

Bahia Grass Care

Fertilizer Requirements

Before investing in fertilizer, perform a soil-nutrient test to determine the pH and available nutrients. This simple test takes a few minutes to complete.

  • A standard lawn fertilizer comprises a lot of nitrogen and trace amounts of phosphorus and potassium. The levels of each are found on the product label.
  • Spread granular fertilizer by hand or with a walk-behind spreader.
  • Mix organic materials, such as manure or peat moss, into the soil to decrease the pH and apply dolomite lime with a spreader to raise the pH.
  • Six weeks later, a weed-and-feed fertilizer treatment in the early spring, a basic all-purpose lawn fertilizer in the early summer, and a slow-release fertilizer, such as Milogranite, are usually required for a Bahia grass lawn.
  • When the air temperatures drop in the fall, many homes in the deep south apply winterizing fertilizer to their
  • Bahia grass lawns. Recycled grass clippings provide some nutrients to the soil, reducing fertilizer.
    Bahia grass blades appear yellow due to iron inadequacies in the soil, like a lawn with a nitrogen deficiency. While iron and nitrogen supplements make the grass greener, nitrogen causes the blades to grow taller.
  • Consider an iron supplement if a soil nutrient test shows a sufficient nitrogen level. However, an iron supplement won’t prevent yellowing caused by a nitrogen deficiency, and excess nitrogen will pollute groundwater.

Mowing Best Method

Set the blade height on the lawnmower to three to four inches off the ground.

Mow a Bahia grass lawn every seven to fourteen days during the growing season, depending on rainfall and temperature.

Allow the clippings to settle into the turf, which will create organic fertilizer with each cut.

Tall seed-head stems quickly degrade the appearance of a Bahia grass lawn.
Reduce the mowing frequency to once a month in the winter.

Mulching grass clippings minimizes the amount of fertilizer needed by the turf.

Mower blade maintenance regularly ensures a clean cut. Baiagrass seed-head stems are robust and quickly dull mower blades, causing the grass tips to break, which looks ugly and promotes disease.

Every few cuts, inspect the lawnmower blades and sharpen them as needed. regularly

Water Requirements

The Bahia grass generally thrives in the Southeastern United States. During prolonged drought, the turf stops growing, and the leaf blades turn pale. (Read Weeds With Small White Flowers)

Small amounts of water will quickly revive the grass. In addition, the grass has excellent drought tolerance, making it ideal for large lots without irrigation.

When the leaf blades drop, and footprints remain clear after walking across the grass, homeowners need to use extra irrigation.

Turn on the sprinklers and let them run for 20 minutes per section and avoid watering late in the day.
