Perennial Legumes: A Guide for Home Gardeners
Introduction
Perennial legumes are a valuable addition to any home garden. These plants are easy to grow and provide a number of benefits, including nitrogen fixation, soil improvement, and weed suppression. In this article, we will discuss what perennial legumes are, why you should grow them, and how to care for them.
What are Perennial Legumes?
Legumes are a family of plants that includes beans, peas, and clover. Perennial legumes are those that live for more than two years. This makes them a good choice for gardeners who want to establish a low-maintenance, long-lasting planting.
Benefits of Growing Perennial Legumes
Perennial legumes offer a number of benefits for home gardeners, including:
- Nitrogen fixation: Legumes have the ability to convert nitrogen from the air into a form that plants can use. This helps to improve soil fertility and reduce the need for chemical fertilizers.
- Soil improvement: Perennial legumes help to improve soil structure by adding organic matter and loosening compacted soil. They also help to prevent erosion.
- Weed suppression: Perennial legumes grow quickly and densely, which helps to crowd out weeds.
- Groundcovers: Perennial legumes can be used as groundcovers to help prevent erosion and suppress weeds. They are also a good choice for areas that are difficult to mow, such as slopes or under trees.
Varieties of Perennial Legumes
There are many different varieties of perennial legumes available, including:
- Clover: Clover is a low-growing legume that is often used as a groundcover. It is also a good choice for attracting pollinators.
- Alfalfa: Alfalfa is a tall-growing legume that is often used for hay or silage. It is also a good source of nitrogen for the soil.
- Crown vetch: Crown vetch is a trailing legume that is often used to control erosion on slopes.
- Birdsfoot trefoil: Birdsfoot trefoil is a low-growing legume that is often used in pastures. It is also a good source of nectar for bees.
- Perennial peanuts: Perennial peanuts are a low-growing legume that is often used as a groundcover. They are also a good source of food for wildlife.
How to Grow Perennial Legumes
Perennial legumes are relatively easy to grow. Here are a few tips:
- Choose the right variety: Select a variety of perennial legume that is well-suited to your climate and soil conditions.
- Prepare the soil: Perennial legumes grow best in well-drained soil that is rich in organic matter.
- Plant in full sun: Most perennial legumes need full sun to grow well.
- Water regularly: Water perennial legumes regularly, especially during hot, dry weather.
- Fertilize sparingly: Perennial legumes do not need much fertilizer. If you do fertilize, use a balanced fertilizer that is low in nitrogen.
Troubleshooting
Perennial legumes are generally low-maintenance plants, but there are a few problems that you may encounter.
- Yellowing leaves: Yellowing leaves may be a sign of nitrogen deficiency. Try fertilizing the plants with a balanced fertilizer that is high in nitrogen.
- Stunted growth: Stunted growth may be a sign of phosphorus deficiency. Try fertilizing the plants with a balanced fertilizer that is high in phosphorus.
- Weeds: Weeds can be a problem in perennial legume plantings. Control weeds by mowing, hoeing, or pulling them by hand.
