Tall fescue is a popular choice for many commercial properties due to its durability, adaptability, and lush appearance. 

Understanding how to properly grow and care for tall fescue can significantly enhance the aesthetics of commercial landscapes. 

This guide will walk you through the essential steps and considerations for cultivating and maintaining tall fescue, ensuring your commercial property in Vista, San Marcos, or Carlsbad, CA, looks its best year-round.

What is Tall Fescue?

Tall fescue is a cool-season grass known for its deep green colour, coarse texture, and high tolerance to heat and drought. 

It thrives in various soil types and is commonly used in commercial landscaping maintenance due to its low maintenance requirements and resilience.

Benefits of Tall Fescue for Commercial Properties

Tall fescue offers several benefits that make it ideal for commercial properties, including:

Durability: It can withstand heavy foot traffic, making it perfect for high-traffic areas.

Drought Resistance: Tall fescue has deep roots that enable it to access water from deeper soil layers, making it more drought-resistant than other grass types.

Low Maintenance: Once established, tall fescue requires less frequent mowing and fertilisation compared to other grasses.

Versatility: It grows well in sun and partial shade, making it adaptable to various landscape designs.

How to Grow Tall Fescue

Choosing the Right Time for Planting

The optimal time to plant tall fescue is in early autumn or spring. 

During these periods, the soil temperature ranges from 15°C to 24°C (59°F to 75°F), which is ideal for seed germination and root development. 

Planting during these seasons gives the grass enough time to establish before the extreme summer or winter temperatures.

Soil Preparation

Proper soil preparation is crucial for the successful growth of tall fescue. Follow these steps:

Test the Soil: Conduct a soil test to determine its pH level and nutrient content. Tall fescue prefers a pH between 5.5 and 7.0.

Amend the Soil: Based on the soil test results, amend the soil with lime to adjust pH or add organic matter to improve soil structure and fertility.

Till the Soil: To loosen the soil to a depth of 6-8 inches to remove any debris or rocks.

Sowing the Seeds

Sowing the seeds properly ensures even coverage and healthy growth. Here’s how to do it:

Seed Selection: Choose high-quality tall fescue seeds suitable for your region’s climate.

Seed Rate: Sow the seeds at a rate of 6-8 pounds per 1,000 square feet for optimal coverage.

Even Distribution: Use a broadcast spreader to ensure the even distribution of seeds across the prepared soil.

Rake and Water: Lightly rake the soil to cover the seeds, then water gently but thoroughly to initiate germination.

Watering

Proper watering is essential during the establishment phase:

Initial Watering: Keep the soil consistently moist until the seeds germinate, usually within 7-14 days.

Deep Watering: Once established, water deeply but infrequently to encourage deep root growth. Watering once or twice a week is typically sufficient.

Caring for Tall Fescue

Mowing

Regular mowing helps maintain the health and appearance of tall fescue:

Mowing Height: Maintain a height of 2.5 to 3.5 inches to ensure the grass remains healthy and robust.

Frequency: Mow as needed, ensuring not to remove more than one-third of the grass blade at a time to prevent stress.

Seasonal Care Tips

Spring Care

Spring is a critical time for tall fescue care:

• Fertilisation: Apply a balanced fertiliser to promote new growth.
• Weed Control: Use pre-emergent herbicides to prevent weed seeds from germinating.
• Aeration: Aerate the soil to improve water and nutrient absorption.

Summer Care

Summer can be stressful for tall fescue due to high temperatures:

• Watering: Water deeply and less frequently to encourage deep root growth.
• Mowing: Maintain a higher mowing height to reduce stress on the grass.
• Fungicide Application: Monitor for diseases and apply fungicides if necessary.

Autumn Care

Autumn is a time for preparing tall fescue for winter:

• Fertilisation: Apply a balanced fertiliser to strengthen the grass for winter.
• Overseeding: To fill in thin areas and promote a dense lawn, consider overseeding.
• Dethatching: Remove any excess thatch to improve soil and root health.

Winter Care

During winter, tall fescue goes dormant but still requires some care:

• Minimise Foot Traffic: Avoid heavy traffic on the lawn to prevent damage.
• Clear Debris: Keep the lawn free of leaves and debris to reduce the risk of disease.

Fertilisation

Fertilising tall fescue promotes healthy growth and vibrant colour:

Timing: Fertilize in early spring and autumn for best results.

Type of Fertilizer: Use a balanced fertiliser with equal parts nitrogen, phosphorus, and potassium or one formulated specifically for tall fescue.

Application: Follow the manufacturer’s instructions for application rates and methods.

Weed Control

Weeds can compete with tall fescue for nutrients and water. Implementing effective weed control measures is crucial:

Pre-emergent Herbicides: Apply pre-emergent herbicides in early spring to prevent weed seeds from germinating.

Post-emergent Herbicides: Use post-emergent herbicides to target existing weeds without harming the tall fescue.

Addressing Common Issues

Thatch Buildup

Thatch is a layer of organic material that can accumulate between the soil and grass blades, potentially suffocating the grass:

Dethatching: Perform dethatching in the spring or autumn using a dethatching rake or machine to remove the excess thatch layer.

Disease Prevention

Tall fescue is susceptible to certain diseases, such as brown patch and dollar spot:

Proper Watering: Avoid overwatering and water early in the day to allow the grass to dry before evening.

Fungicides: Apply fungicides as needed to control outbreaks.

Conclusion

Tall fescue is an excellent choice for commercial properties due to its resilience, low maintenance requirements, and attractive appearance. 

By following the proper planting and care guidelines, you can ensure a lush, healthy lawn that enhances the appeal of your commercial landscape in Vista, San Marcos, or Carlsbad, CA.

FAQs

Q: What are the best conditions for tall fescue to grow?

Best Conditions for Tall Fescue to Grow

Climate

Tall fescue is a cool-season grass that thrives in temperate climates. It grows best in regions with moderate temperatures and performs well in both spring and autumn. 

It can tolerate hot summers and cold winters better than many other cool-season grasses, making it suitable for a wide range of climates.

Soil

Tall fescue prefers well-drained soils with a pH range of 5.5 to 7.0. It can adapt to a variety of soil types, including clay, loam, and sandy soils. 

Proper soil preparation, including testing and amending soil as necessary, helps ensure optimal growth conditions.

Sunlight

This grass variety grows best in full sun but can tolerate partial shade. Ideally, it should receive at least 4-6 hours of direct sunlight daily. 

Shadier areas will require additional care and monitoring to ensure the grass remains healthy.

Watering

Tall fescue has a deep root system that allows it to access water from deeper soil layers. During establishment, keep the soil consistently moist. 

Once established, water deeply but infrequently, usually once or twice a week, to promote deep root growth.

Fertilisation

Regular fertilisation helps maintain the health and vibrant colour of tall fescue. Apply a balanced fertiliser in early spring and autumn. 

Follow the manufacturer’s recommendations for application rates and methods to avoid over-fertilising, which can damage the grass and the environment.

Q: What are the disadvantages of tall fescue?

Disadvantages of Tall Fescue

Coarse Texture

Tall fescue has a coarser texture compared to other grass types like Kentucky bluegrass or fine fescues. This texture may not be preferred for high-end lawns or golf courses where a finer, softer grass is desired.

Thatch Buildup

Tall fescue can develop a thatch layer, which is a build-up of organic material between the grass and the soil. 

Thatch can suffocate the grass if not managed properly. Regular dethatching is necessary to prevent excessive thatch accumulation.

Disease Susceptibility

Tall fescue is susceptible to certain fungal diseases, such as brown patches and dollar spots. 

Proper watering practices, avoiding over-fertilisation, and timely fungicide applications can help manage these issues.

Establishment Time

While tall fescue is relatively easy to establish, it can take longer to fill in completely compared to some other grass types. 

Overseeding may be necessary to achieve a dense, uniform lawn.

Q: What is the best grass to mix with tall fescue?

Best Grass to Mix with Tall Fescue

Kentucky Bluegrass

Kentucky bluegrass is often mixed with tall fescue to enhance the overall quality of the lawn. Kentucky bluegrass has a finer texture and forms a dense, lush turf. 

When combined with tall fescue, it provides a balance of durability and aesthetic appeal. Kentucky bluegrass also has excellent recovery rates, helping to fill in bare spots more quickly.

Fine Fescues

Fine fescues, such as creeping red fescue or hard fescue, can be mixed with tall fescue to improve shade tolerance and texture. 

Fine fescues have a finer blade and can thrive in shaded areas, complementing the coarser texture and sun tolerance of tall fescue.

Perennial Ryegrass

Perennial ryegrass is another good companion grass for tall fescue. It germinates quickly and helps establish a green lawn faster. 

Perennial ryegrass also has a fine texture and provides a dense, attractive turf when mixed with tall fescue.

Q: What is the best height to keep tall fescue?

Best Height to Keep Tall Fescue

Recommended Mowing Height

The ideal mowing height for tall fescue is between 2.5 to 3.5 inches. Keeping the grass at this height helps promote a strong root system and improves the grass’s ability to withstand drought and heat.

Mowing Frequency

Mow tall fescue regularly, but avoid removing more than one-third of the grass blade at a time. Frequent mowing at the recommended height helps maintain the health and appearance of the lawn. 

During periods of rapid growth, you may need to mow more frequently, while during slower growth periods, mowing less often is acceptable.

Seasonal Adjustments

Adjust the mowing height based on seasonal conditions:

• Spring and Autumn: Maintain the recommended height of 2.5 to 3.5 inches.
• Summer: Raise the mowing height slightly to help the grass retain moisture and reduce stress.
• Winter: In regions where tall fescue remains green during winter, keep the mowing height at the upper end of the recommended range to protect the grass from cold temperatures.

By following these guidelines, you can ensure that tall fescue remains healthy, vibrant, and well-maintained throughout the year.
