Killing Weeds in Buffalo Lawn: A Comprehensive Guide

Killing weeds in your buffalo lawn can be a challenge, but it's essential to keep your lawn healthy and looking its best.

Buffalo grass is a low-maintenance option, but it's still susceptible to weeds like crabgrass and clover.

One of the most effective ways to kill weeds is to use a pre-emergent herbicide in early spring.

Buffalograss is a beautiful and low-maintenance lawn option, but it's not immune to weed infestations. Crabgrass and foxtail are problematic summer annual weeds that can infiltrate buffalograss, and broadleaf weeds like henbit, dandelion, and chickweed are common invaders.

Some weeds, like henbit and dandelions, can germinate and grow back quickly, especially after rains and cooler temperatures. It's essential to control these weeds when they're small to prevent them from getting fully established.

Pre-emergent herbicides can be used in the spring to control summer annuals like crabgrass and foxtail. Recommended pre-emergent herbicides for buffalograss include Barricade (prodiamine), Pendulum Aquacap (pendimethalin), Dimension (dithiopyr), and Specticle (indaziflam).

If you're dealing with weeds in your new buffalograss lawn (less than a year old), Round Up or other glyphosate herbicides can be used to control existing weeds before seeding. However, be sure to check the product label for the waiting period before planting new seed.

To control weeds in new buffalograss, you can also use pre-emergent herbicides after buffalograss emergence. Barricade (prodiamine) can be applied 60 days after spring seeding.

Here are some post-emergent herbicides that can be safely used on first-year buffalograss:

Remember to always read and follow the chemical label application instructions for best results.

You can't just spray the weeds in your buffalo lawn like you would in any other situation, as buffalo lawns are vulnerable to harsh chemicals in many common weed killers.

Herbicides containing dicamba are particularly harmful to buffalo grass and can even kill the whole yard if you're not careful.

If you spot weeds early enough, you can remove them by hand before seed heads develop, which is a great perk of buffalo grass.

Buffalo grass only contains stolons, or above-ground roots, making it easy to pull out unwanted weeds.

A line trimmer is a great tool for taller weeds, as they tend to grow much faster than the buffalo grass itself.

Weeds in your buffalo lawn can be a real nuisance, but understanding the types of weeds you're dealing with is key to effective control. There are three main classes of weeds: broadleaf, grassy, and sedge.

Broadleaf weeds are easy to spot, with two seed leaves and broader leaves and branched stems. Examples of broadleaf weeds include henbit, dandelion, and chickweed. Grassy weeds, on the other hand, produce one seed leaf, just like regular turfgrass, and include weeds like goosegrass and crabgrass.

To identify your weeds, you can check if they have a triangular shape in cross-section, which is a characteristic of sedge weeds like yellow nutsedge. If you're still unsure, consider consulting a reliable source like the Weed Science Society of America or your local County Extension Service for help with weed identification.

Weed types can be tricky to identify, but knowing the basics can make a big difference. There are three main classes of weeds: broadleaf, grassy, and sedge.

Broadleaf weeds are easy to spot because they produce two seed leaves as they emerge, and their leaves are generally broader and branched.

Grassy weeds, on the other hand, produce only one seed leaf, similar to regular turfgrass. Some common examples of grassy weeds include goosegrass, crabgrass, and rushes.

Sedges also produce only one seed leaf, but their leaves are triangular in cross-section, like yellow nutsedge.

Here's a quick rundown of the three weed types:

Annual weeds live for just one season, making them easier to control. This is because once they've flowered and gone to seed, they'll die soon anyway.

Perennial weeds, on the other hand, recur yearly from the same root system. This means they can be more challenging to get rid of.

Some common annual weeds include crabgrass and foxtail, which are problematic summer annual weeds. These types of weeds require monitoring and sometimes control measures.

Here's a quick breakdown of the difference between annual and perennial weeds:

Henbit, dandelion, and chickweed are examples of broadleaf weeds that regularly infiltrate buffalograss. Each of these types of weeds requires monitoring and sometimes control measures.

When you're ready to tackle those pesky weeds in your buffalo lawn, you'll need to choose the right herbicide. There are several types to consider, including liquid and granular formulas.

Liquid herbicides are usually mixed with water and sprayed from a handheld or backpack pump sprayer. Granular herbicides, on the other hand, are mixed with an inert carrier like clay, lime, or a fertilized carrier and spread from a fertilizer spreader.

You'll also need to decide between selective and nonselective herbicides. Selective herbicides kill specific plants, while nonselective herbicides kill whatever they touch. If you choose a nonselective herbicide, you'll need a spray bottle and careful aim to avoid damaging your lawn.

Here are the key differences between liquid and granular herbicides:

Liquid herbicides are usually mixed with water and sprayed from a handheld or backpack pump sprayer. This is a convenient option for small areas or spot treatments.

Granular herbicides are mixed with an inert carrier like clay, lime, or a fertilized carrier and spread from a fertilizer spreader. This method is often used for larger areas.

Selective herbicides kill specific plants, and they're labeled as "broadleaf herbicide" or something similar. This means you can spray them without killing your grass.

Nonselective herbicides kill whatever they touch, so you need a spray bottle and careful aim. This type of herbicide requires more precision to avoid damaging your turfgrass.

Expand your knowledge: Spray for Weeds in Lawn

You have two main options for spraying herbicides: broadcast or spot spraying.

Broadcast spraying applies the herbicide across the entire lawn, which is suitable for selective weed killers since the grass can tolerate it.

Spot treatments use an applicator to apply the herbicide directly to the weed, minimizing damage to other plants.

To spot spray effectively, target only the weeds you want, using a foam applicator or precise spraying.

When broadcast spraying, cross your lawn with each pass at a steady pace, making sure you're not leaving untreated strips.

Maintain a spray height about 2 feet above the grass to encourage maximum coverage and reduce the potential for drift.

Here's a quick comparison of the two techniques:

Both methods require careful attention to detail to ensure effective results.

Pre-emergent herbicides are a type of herbicide that can be used to control weeds before they germinate. They're most effective on small-seeded weeds like crabgrass.

The key to using pre-emergent herbicides is timing. You need to apply them before the soil temperature reaches 52 degrees Fahrenheit, which is when crabgrass and other seeds begin to germinate. This can be as early as late April or early May, depending on your location.

Pre-emergent herbicides can be applied in the spring or fall to control summer and winter annual weeds. For summer annuals, apply the herbicide just before the soil temps reach 52 F to control pesky weeds like crabgrass, foxtail, and goosegrass. For winter annuals, apply when the soil temps reach 70 F to stop weeds like poa annua and filaree from sprouting.

Here's a breakdown of when to apply pre-emergent herbicides:

Timing is everything when it comes to applying pre-emergent herbicides. It's best to apply them just before the soil temperatures reach 52 F to control summer annual weeds like crabgrass, foxtail, and goosegrass.

Choose a day that's 50 degrees or higher for optimal results. This allows the weed killer to move from the leaves to the roots more efficiently.

If you're planning to apply pre-emergent herbicides for winter annual weeds, wait until the soil temperatures reach 70 F. This will help prevent weeds like poa annua and filaree from sprouting above the soil surface.

It's not too late to prepare your landscape for a buffalograss lawn planting next year, and timing your weed control efforts now can make a big difference in the long run.

Pre-emergent herbicides are a crucial tool for controlling weeds in your buffalograss lawn. They need to be applied before the soil temperature hits 52 degrees Fahrenheit for them to be effective.

The key to using pre-emergent herbicides is knowing when to apply them. For summer annual weeds like crabgrass and foxtail, apply just before the soil temps reach 52 F. For winter annual weeds like poa annua and filaree, apply when the soil temps reach 70 F.

If you procrastinated and are now too late to apply a pre-emergent, have no fear! Selective and nonselective herbicides are usable whenever you find the plants actively growing. However, these post-emergents work best early in the season when the weeds are still small.

Here's a quick rundown of the best times to apply herbicides:

Remember to follow the label's directions and don't saturate an area with a post-emergent herbicide. It will be washed past the plants and into the soil, where it may damage other plants or get into water sources. Reapply as needed, but be careful not to overdo it.

In the first year of buffalograss growth, you can use Round Up or other glyphosate herbicides to control weeds before seeding. After buffalograss emergence, you can use pre-emergent herbicides to control weeds that germinate later in the season.

To kill weeds in your buffalo lawn, you'll want to choose the right herbicide, which can be either selective or non-selective. Selective herbicides target specific weeds without harming your buffalo grass, while non-selective herbicides will kill everything they touch.

For a buffalo lawn, it's best to use a selective herbicide that contains 2,4-D or dicamba, as these are effective against broadleaf weeds like dandelions and clover.

If you decide to use a non-selective herbicide, make sure to apply it early in the morning or late in the evening to minimize drift onto your buffalo grass.

To minimize the risk of drift, it's essential to use a sprayer with a coarse spray nozzle, which will help reduce the amount of herbicide that reaches your buffalo grass.

The recommended application rate for 2,4-D is 1-2 ounces per gallon of water, and for dicamba, it's 2-4 ounces per gallon of water. Always read the label and follow the instructions carefully to avoid over-application.

It's also crucial to wear protective clothing, including long sleeves, long pants, and closed-toe shoes, when applying herbicides to prevent skin contact and exposure.

Fertilizing your buffalo lawn is crucial for its health and growth.

Fertilizers should be applied at the right time to avoid harming your lawn.

For example, in Louisiana, the best time to apply a nitrogen-containing fertilizer is later than the time for making an initial application of a pre-emergence herbicide for crabgrass.

Nitrogen-containing fertilizers promote healthy growth, but applying them too early can lead to weak and spindly grass.

To avoid this, it's essential to keep your herbicide and fertilizer treatments separate.

This will help your grass grow strong and resilient in the long run.
