Introduction to Clover Lawns
Clover lawns have gained popularity in recent years due to their eco-friendly characteristics and low maintenance needs. There are several types of clover, with white clover (Trifolium repens) and microclover (Trifolium microphyllum) being the most commonly used for lawns. These varieties are known for their ability to fix nitrogen, suppress weeds, and attract beneficial insects. Unlike traditional grass lawns, clover lawns require less water, mowing, and fertilization, making them an attractive option for homeowners looking to reduce their environmental footprint.
Benefits of Planting Clover Over Existing Grass
Planting clover over existing grass offers several benefits, including:
- Improved Soil Health: Clover has the ability to fix atmospheric nitrogen into the soil, reducing the need for synthetic fertilizers. This process also improves soil structure and increases the population of beneficial microorganisms.
- Increased Drought Tolerance: Clover lawns are more resistant to drought than traditional grass lawns, requiring less water to maintain their health and appearance.
- Reduced Mowing Needs: Clover grows closer to the ground than most grass species, reducing the need for frequent mowing. This not only saves time but also decreases the consumption of gasoline and the emission of pollutants.
- Weed Suppression: Clover can outcompete many weed species, reducing the need for herbicides and other weed control methods.
Choosing the Right Type of Clover
When deciding to plant clover over existing grass, it’s essential to choose a variety that suits your climate, soil type, and intended use of the lawn. White clover and microclover are popular choices for their durability, appearance, and low maintenance requirements. White clover is more aggressive and can outcompete existing grass more effectively, while microclover is finer in texture and can create a denser, more uniform lawn.
Preparation and Planting
Preparing your lawn for clover involves several steps to ensure a successful transition. The process can be time-consuming, but the end result is well worth the effort.
Assessing Your Lawn
Before planting clover, assess your lawn’s condition. Consider factors such as soil pH, nutrient levels, and the presence of weeds or pests. Clover prefers slightly acidic to neutral soils (pH 6.0-7.0), so a soil test may be necessary to determine if amendments are required.
Reducing Existing Grass
To give clover seeds the best chance to germinate and grow, it’s crucial to reduce the competition from existing grass. This can be achieved through several methods:
- Mowing Low: Mow your lawn as low as possible to reduce the grass height and stress the existing grass.
- Solarization: Trapping the sun’s heat under a clear plastic tarp can kill grass and weeds without using herbicides.
- Sheet Mulching: Applying a layer of organic mulch and letting it decompose can smother the existing grass.
Seeding and Mulching
Once the existing grass is sufficiently reduced, it’s time to seed the clover. Spread the clover seeds evenly, following the package instructions for the correct seeding rate. After seeding, apply a thin layer of organic mulch to retain moisture, suppress weeds, and regulate soil temperature.
Maintenance and Care
Clover lawns require less maintenance than traditional grass lawns, but some care is still necessary to ensure they remain healthy and looking their best.
Mowing and Watering
Clover lawns should be mowed occasionally to maintain a uniform height and promote dense growth. It’s also essential to water the lawn adequately, especially during the establishment phase. However, clover is drought-tolerant, so watering can be reduced once the lawn is established.
Fertilization and Pest Control
Given clover’s ability to fix nitrogen, fertilization needs are significantly reduced. However, an annual application of compost or well-rotted manure can provide other essential nutrients. For pest control, natural methods such as introducing beneficial insects or using neem oil can be effective, reducing the reliance on chemical pesticides.
Overseeding and Renovation
As clover lawns age, they may require overseeding to maintain their density and appearance. This can be done annually or every few years, depending on the lawn’s condition. For lawns that have become heavily infested with weeds or have thinned out significantly, a full renovation, including re-seeding and re-mulching, may be necessary.
