Understanding Tall Fescue and Weeds

Tall Fescue grass is a common cool-season turfgrass species found in many lawns, parks, and sports fields. While it has good drought tolerance and can grow in a range of soil types, it is susceptible to weed invasion, which can make lawns look unsightly and reduce their vigor.

Why It's Important to Keep Weeds Under Control

Weeds are unwanted vegetation that compete with desirable plants for resources such as water, light, and nutrients. They can also harbor pests and diseases, which can attack the turfgrass, further reducing its growth and health.

Common Tall Fescue Weeds to Watch Out For

Some of the most common weeds found in tall fescue lawns include:

• Crabgrass
• Dandelions
• Clover
• Nutsedge
• Plantain
• Chickweed

Methods of Tall Fescue Weed Control

There are three main methods of controlling weeds in tall fescue lawns: cultural, mechanical, and chemical.

1. Cultural methods

Cultural methods involve making changes to the environment to reduce weed growth without the use of herbicides. Here are some examples:

• Mowing the lawn regularly and at the right height (3-4 inches) to prevent weed seeds from germinating and to promote dense turfgrass growth.
• Watering deeply and infrequently to encourage deep root growth and greater drought tolerance.
• Fertilizing the lawn with the appropriate nutrients to promote strong turfgrass growth and competitiveness against weeds.
• Overseeding bare or thin areas with more desirable turfgrass varieties to fill in gaps and reduce opportunities for weed establishment.
• Removing weeds by hand or with a weed puller before they have a chance to go to seed.

2. Mechanical methods

Mechanical methods involve physically removing or damaging weeds without the use of chemicals. Some examples include:

• Using a dethatcher or power rake to remove excessive thatch buildup, which can make it difficult for grass roots to absorb water and nutrients and can provide an ideal environment for weed growth.
• Aerate the lawn to relieve soil compaction and improve air and water infiltration, making it easier for turfgrass to grow strong roots.
• Using a sod cutter or manual edger to remove weeds growing near sidewalks, driveways, or other hardscape areas where chemical use is not desirable.
• Using a hoe or cultivator to loosen weeds from the soil and uproot them manually.

3. Chemical methods

Chemical methods involve the use of herbicides to control weeds. Before choosing this method, it is essential to know the type of weeds you have in your lawn, and to select the appropriate herbicide for the specific weed. Here are some examples of commonly used herbicides for tall fescue lawns:

• Pre-emergent herbicides like pendimethalin, prodiamine, and dithiopyr, which work by preventing weed seeds from germinating.
• Post-emergent herbicides like 2,4-D, dicamba, and MCPP, which target actively growing broadleaf weeds but do not harm most grasses.
• Selective herbicides like quinclorac, which control tough-to-kill grassy weeds like crabgrass and dallisgrass without harming desirable grasses.
• Non-selective herbicides like glyphosate, which kill everything they touch, including desirable grasses, and should be used only as a last resort when other methods have failed.

Taking Action against Tall Fescue Weeds

Preventing and controlling weeds in tall fescue lawns requires a combination of cultural, mechanical, and chemical methods. Implementing good lawn care practices like proper watering, fertilizing, and mowing will create conditions that promote thick, healthy turfgrass growth, which will help suppress weed development. Adding overseeding to your maintenance routine helps ensures an overall dense turf.

Monitoring your lawn for the presence of weeds is recommended even after you have done management as perennial grass/weed can continuously grow in some soil types

Maintaining Healthy and Weed-Free Tall Fescue

Maintaining healthy and weed-free tall fescue lawns takes ongoing attention, but you can achieve it with patience and persistence. By following these tips, you can control weeds and promote excellent turfgrass growth, creating an attractive, healthy lawn that enhances your home's value.

FAQ

Here are answers to some commonly asked questions about controlling tall fescue weeds:

1. What are some common tall fescue weeds? Some of the most common weeds found in tall fescue lawns include Crabgrass, Dandelions, Clover, Nutsedge, Plantain, Chickweed.

2. What cultural methods can I use to control tall fescue weeds? You can use a couple of methods such as proper watering, fertilizing lawns as well as mowing to reduce tall fescue weeds

3. Which chemical herbicides are effective in controlling tall fescue weeds? Some commonly used herbicides for tall fescue lawns include Pre-emergent herbicides, Post-emergent herbicides, Selective herbicides are most effective at controlling different weeds.

4. Are there any natural ways to control tall fescue weeds? Hand weeding or using organic solutions such as vinegar or citrus oil can be helpful in eradicating small patches of weeds.

5. When is the best time of year to control tall fescue weeds? Timing is essential because weeds have different life cycles. Broadleaf weed control works best when applied in spring and fall when active growth is happening, while Pre-emergent herbicides are ideal to apply once or twice a year.

6. How can I prevent tall fescue weeds from cropping up in my lawn? Maintaining healthy grass by mowing correctly, ensuring proper watering, and fertilization can effectively prevent the development of tall fescue weeds.

7. Can irrigation affect the growth of tall fescue weeds? Proper watering practices can help discourage the establishment of shallow-rooted weeds in lawns. Deep watering protects grass roots and may help suppress weeds.

8. What specific mechanical methods are most effective in controlling tall fescue weeds? Dethatching or power raking, Aeration; removing weeds by hand or with a weed puller before they go to seed, and Manual edger or Sod cutter to remove weeds near sidewalks or hardscape areas

9. Is it necessary to hire a professional for tall fescue weed control, or can I do it myself? Most property managers and homeowners can do Tall Fescue Weed Control if given enough time and patience - however, you might require professional help for large lawns and mature weeds.

10. What is the cost involved in controlling tall fescue weeds? The cost depends primarily on the method used as well as the size of the area to be treated. Cultural methods such as proper mowing, fertilizer application and overseeding may take time but could save you from chemical applications. On the other hand, mechanical treatments like dethatching, aerating, and sod cutting require specialized equipment, and chemical applications depend on product usage in your case.
