Benefits of Planting Clover

Improves Soil Health

One of the key benefits of planting clover is its ability to improve soil health. Clover belongs to a group of plants known as legumes, which have a unique ability to fix nitrogen from the atmosphere and convert it into a form that plants can readily use. This process, known as nitrogen fixation, helps to increase the availability of this vital nutrient in the soil. The increased nitrogen levels promote healthier plant growth and can lead to higher crop yields. Additionally, clover’s deep root system helps to improve soil structure, reducing erosion and increasing water infiltration.

Increases Nitrogen Levels

Clover is renowned for its ability to increase nitrogen levels in the soil. Legumes like clover have a symbiotic relationship with certain bacteria called rhizobia. These bacteria live in nodules on the roots of legume plants and can convert atmospheric nitrogen into a form that the plant can use. By planting clover in your garden or field, you are essentially harnessing the power of these beneficial bacteria to increase nitrogen levels naturally. This can be particularly beneficial for crops that have a high demand for nitrogen, such as corn or lettuce.

Enhances Pollinator Habitat

Clover flowers are a rich source of nectar and pollen, making them highly attractive to pollinators such as bees, butterflies, and hummingbirds. By planting clover, you can provide a valuable food source for these important insects and contribute to the conservation of pollinator populations. The presence of pollinators can also improve fruit set in crops, leading to higher yields. Creating a habitat for pollinators in your garden or field not only benefits your plants but also supports overall biodiversity in the surrounding ecosystem.

Reduces Weeds

Clover can act as a natural weed suppressor due to its rapid growth and ability to form a dense ground cover. When established, clover can effectively outcompete many common weed species, reducing the need for herbicides or manual weed control. The dense canopy created by clover acts as a living mulch, shading out weeds and limiting their germination and growth. This makes clover an excellent addition to organic farming systems or areas where chemical herbicides are undesirable.

Promotes Biodiversity

Planting clover can have a significant impact on promoting biodiversity. The presence of clover in a field or garden can attract a wide range of beneficial insects, including predatory beetles, parasitic wasps, and hoverflies, which help control pest populations. By providing a diverse food source and habitat, clover encourages the presence of these beneficial insects, creating a balanced ecosystem that reduces the need for chemical pest control. The increased biodiversity can also enhance the overall health and resilience of the ecosystem, making it more resistant to disease outbreaks and other environmental stresses.

Types of Clover

White Clover (Trifolium repens)

White clover is a low-growing perennial clover that is widely used in agricultural systems and lawns. It has a prostrate growth habit, with creeping stems that form a dense mat. White clover is known for its ability to tolerate a wide range of soil conditions, including poor drainage and low fertility. It can be used as a ground cover, in pasture mixes, or as a nitrogen-fixing cover crop.

Dutch clover, also known as ladino clover, is a white clover variety that is well-suited for hay production, grazing, or as a cover crop. It has a more upright growth habit compared to standard white clover varieties and tends to have larger leaves. Dutch clover performs best in fertile soils and can be used in a variety of agricultural and landscaping applications.

When to Plant Clover

Spring Planting

Spring is an ideal time to plant clover, as soil temperatures begin to warm up, and the risk of frost has diminished. Depending on your region, the best time for spring planting can vary. It’s generally recommended to plant clover in spring when soil temperatures reach around 50°F (10°C) or above. This ensures that the clover seeds will have favorable conditions for germination and establishment.

Spring-planted clover will have the entire growing season to establish itself before the onset of winter, resulting in a stronger and more robust plant.

Fall Planting

Fall is another favorable time for planting clover, especially in regions with mild winters. Planting clover in the fall allows it to establish a strong root system during the cooler months and provides a head start in the following spring. Fall-planted clover can also help prevent soil erosion during the winter months by providing ground cover.

It’s recommended to plant clover in the fall at least six to eight weeks before the first frost date in your region. This allows the clover plants to establish themselves before the onset of freezing temperatures.

Site Selection for Clover

Soil Type and pH

Clover is adaptable to a wide range of soil types, from sandy to clay soils. However, it thrives best in well-draining soils with good organic matter content. When selecting a site for clover, ensure that the soil is not excessively compacted, as it may hinder proper root development. Conduct a soil test to determine the pH level of the soil, as clover prefers slightly acidic to neutral pH levels ranging from 6.0 to 7.0. If the soil pH is too low or too high, adjust it accordingly before planting.

Sunlight Requirements

Most clover varieties perform best in full sun or partial shade. Ensure that the selected site receives at least 4-6 hours of direct sunlight per day for optimal growth. In hotter climates, partial shade during the hottest part of the day can help prevent wilting and heat stress in clover plants.

Drainage

Proper drainage is crucial for clover since it prefers well-drained soils. Avoid planting clover in areas prone to waterlogging, which can lead to root rot and other diseases. If the soil has poor drainage, consider implementing soil amendments or raised bed gardening techniques to improve the drainage characteristics of the site.

Companion Plants

Consider the compatibility of clover with other plants when selecting a site. Clover can coexist well with a variety of common garden and agricultural plants. It can be planted as an understory cover crop in orchards or used as a living mulch between rows of crops such as tomatoes or peppers. Avoid planting clover in areas that will be heavily disturbed or cultivated frequently, as this can damage the delicate clover plants.

Preparing the Soil for Clover

Clearing the Area

Before planting clover, clear the area of any existing vegetation, weeds, or debris. This ensures that there is no competition for resources between the clover plants and other plants. Remove any large rocks or obstructions that may hinder the growth of the clover plants.

Amending the Soil

Based on the results of the soil test, you may need to amend the soil before planting clover. Common soil amendments for clover include adding organic matter, such as compost or well-rotted manure, to improve soil structure and fertility. Lime or sulfur may be needed to adjust the soil pH if it falls outside the recommended range for clover.

Seedbed Preparation

Prepare the seedbed by loosening the soil to a depth of 4-6 inches (10-15 cm) using a garden fork or tiller. Remove any remaining rocks, roots, or large clumps of soil. Rake the soil surface to create a fine seedbed, free of large clumps. This will provide an optimal environment for seed germination and root development.

Planting Clover Seeds

Seed Selection

Selecting the right seed variety is crucial for successful clover planting. Consider the specific goals of your planting, such as soil improvement, forage production, or attracting pollinators, when choosing a clover variety. Additionally, select seeds that are labeled for your specific region, as they are often adapted to local growing conditions.

Seed Quantity

The recommended seeding rate for clover varies depending on the specific clover variety and intended use. For lawn alternatives, aim for a seeding rate of 4-6 pounds per 1,000 square feet (2-3 kg per 93 square meters). For agricultural purposes, such as cover cropping or pasture establishment, the seeding rate can range from 12-20 pounds per acre (13-22 kg per hectare). Follow the instructions on the seed packet for specific seeding rates.

Seeding Methods

Clover seeds can be sown using different methods, depending on the scale of the planting. For small areas or precise seed placement, broadcasting the seeds by hand or using a hand-held spreader can be effective. For larger areas, using a mechanical spreader or seed drill can ensure more even seed distribution. After broadcasting or drilling the seeds, lightly rake the soil surface to cover the seeds to a depth of 1/4 to 1/2 inch (6-13 mm). Water the area gently to ensure good seed-to-soil contact.

Watering and Care for Clover

Watering

After planting clover seeds, it’s important to keep the soil evenly moist to support germination and early growth. Water the newly planted area gently to prevent soil erosion or displacement of the seeds. Avoid overwatering, as excess moisture can lead to damping-off disease or root rot. Once the clover plants are established, they generally have good drought tolerance and may not require regular watering, except in prolonged periods of dry weather.

Fertilizing

Clover typically does not require additional fertilization if the soil has been adequately amended before planting. However, if the soil fertility is low, a balanced organic fertilizer can be applied after the initial growth. Avoid using high-nitrogen fertilizers, as clover plants naturally fix nitrogen from the atmosphere. Follow the manufacturer’s instructions for the appropriate application rate and timing.

Mowing and Trimming

Mowing or trimming clover plants is often necessary for maintaining an attractive and manageable appearance. For lawn alternatives or ground cover purposes, mow the clover to a height of 2-4 inches (5-10 cm) periodically to encourage lateral growth and prevent flowering. This will help maintain a dense, green appearance. However, if the goal is to attract pollinators or utilize the clover as a forage crop, allowing the plants to flower and set seed is beneficial.

Weed Control

Clover’s dense growth habit and ability to suppress weed growth can help minimize weed pressure. However, it’s still important to manage weeds to prevent competition for resources. Hand pulling or using a manual weeding tool can be effective for small infestations. Applying a natural mulch or using organic weed control methods, such as solarization or smother cropping, can also help suppress weed growth without the need for herbicides.
