Fescue grass is a popular cool-season grass known for its fine texture, lush appearance, and shade tolerance. Whether you are establishing a new fescue lawn or maintaining an existing one, proper care and mowing techniques are essential for its health and beauty. In this comprehensive guide, we will provide you with step-by-step instructions on how to care for and mow fescue grass to achieve a vibrant and well-maintained lawn.
Understanding Fescue Grass
Before diving into the mowing and care techniques, it’s essential to understand the characteristics of fescue grass. There are several types of fescue grass, with two common varieties being Tall Fescue (Festuca arundinacea) and Fine Fescue (Festuca spp.). Fescue grasses are cool-season grasses, thriving in areas with moderate temperatures and adequate moisture. They exhibit excellent shade tolerance, making them ideal for lawns with partial sun or full shade.
Proper Mowing Height
Mowing at the correct height is crucial for fescue grass health and appearance. Set your mower to a height of 2.5 to 3.5 inches for Tall Fescue and 1.5 to 2.5 inches for Fine Fescue. Avoid cutting more than one-third of the grass height at once, as this can stress the grass and lead to weakened growth.
Mowing at the right height encourages deep root growth, provides shade to the soil, and helps the grass better withstand drought and disease. Taller grass also competes better with weeds, leading to a healthier and more resilient lawn.
Frequency of Mowing
The mowing frequency for fescue grass varies depending on its growth rate. During the peak growing season in spring and fall, mow Tall Fescue lawns every 5 to 7 days and Fine Fescue lawns every 7 to 10 days. In summer, you may need to mow less frequently due to reduced growth.
Monitor your lawn’s growth and adjust the mowing schedule accordingly. Avoid letting the grass become excessively tall before mowing, as this can lead to uneven cutting and clumping of grass clippings.
Note: One-Third Rule: Avoid cutting more than one-third of the grass height at once. Removing more than one-third of the grass blades can stress the grass and weaken its overall health.
Maintain Sharp Mower Blades
Sharp mower blades are crucial for a clean and precise cut. Dull blades tear the grass instead of cleanly cutting it, leading to a ragged appearance and increased vulnerability to disease. Sharpen your mower blades regularly, ideally at the beginning of each mowing season and whenever you notice a decline in cutting performance.
Leave Clippings on the Lawn
Fescue grass lawns benefit from leaving grass clippings on the lawn, a practice known as grasscycling. The clippings decompose quickly, returning valuable nutrients to the soil and reducing the need for fertilization. However, avoid leaving large clumps of clippings on the lawn, as they can smother the grass and create unsightly patches.
Aeration and Overseeding
Fescue grass lawns can benefit from annual aeration, especially in compacted areas or high-traffic zones. Aeration relieves soil compaction, improves water and nutrient absorption, and encourages healthy root development.
Overseeding is also essential for maintaining a dense and vibrant fescue lawn. Overseed in the fall to fill in bare spots, improve grass density, and introduce newer, disease-resistant varieties.
Watering Wisely
Fescue grass has moderate water needs, typically requiring around 1 to 1.5 inches of water per week, including rainfall. Water deeply and infrequently to encourage deep root growth. Watering early in the morning or late in the evening minimizes water evaporation and helps prevent fungal diseases.
Monitor your lawn’s moisture level and adjust the watering schedule based on weather conditions. During periods of drought, fescue grass can enter dormancy to conserve water, but it will recover once water becomes available.
Watering and Irrigation
Time of Day: Water your lawn early in the morning or late in the evening to reduce water evaporation. Watering during the hottest part of the day can result in water loss through evaporation and lead to inefficient water usage.
Rainfall Monitoring: Keep track of rainfall amounts to adjust your watering schedule accordingly. During periods of rainfall, you may need to reduce or skip irrigation to prevent overwatering.
Drought Tolerance: Fescue grass has good drought tolerance and can enter a state of dormancy during extended periods of drought. The grass will recover once water becomes available again.
Fertilization and Soil Nutrients
Soil Testing: Regular soil testing every 2 to 3 years helps determine the nutrient levels in your lawn. Based on the test results, you can apply the appropriate fertilizers and soil amendments to maintain optimal nutrient balance.
Fertilizer Application: Apply a balanced, slow-release fertilizer in the spring and fall when the grass is actively growing. Avoid excessive nitrogen, as it can lead to thatch buildup and weaken the grass.
Organic Fertilizers: Consider using organic fertilizers to promote soil health and reduce the risk of nutrient leaching. Organic options include compost, fish emulsion, and seaweed-based fertilizers.
Overseeding and Aeration: Overseed your fescue lawn in the fall to fill in bare spots and improve grass density. Aerate the lawn annually to relieve soil compaction and improve root development.
Fertilization
Fertilize your fescue lawn based on soil test results and the specific needs of your grass. Generally, fescue lawns benefit from two to four applications of a balanced fertilizer throughout the year, with the majority applied in the fall and spring when grass growth is most active.
Avoid excessive fertilization, as it can lead to thatch buildup and weaken the grass. Follow the manufacturer’s instructions for application rates and timings.
Pest and Disease Management
Keep an eye out for common lawn pests and diseases that can affect fescue grass. Proper cultural practices, such as mowing at the correct height, watering deeply, and aerating, can help prevent disease development.
For pest infestations or severe disease outbreaks, consult with a lawn care professional or extension office for appropriate treatment options.
Weed Control
A dense and healthy fescue lawn is the best defense against weeds. However, if weeds do appear, spot-treat them using appropriate herbicides. Use pre-emergent herbicides in the early spring to prevent weed seeds from germinating.
