Hairy Vetch

Hairy Vetch is a cool-season perennial legume that can be used as green manure in raised beds. It germinates quickly and produces high yields of nitrogen-rich biomass. In addition, Hairy Vetch benefits the soil by improving soil fertility, suppressing weeds, and creating a seed bank for next year’s crops.

Hairy Vetch should be seeded in moist soils in late summer or early fall. Sow seeds 1/4-inch-deep and cover with soil. Water well immediately after planting and again 2–3 weeks later. Once the plants grow tall enough to reach the surface of the soil, they are ready to mow or harrow.

Sorghum

Many cover crops can protect and enrich the soil around raised beds. Rye can grow quickly and provide significant coverage to the soil around the bed. Additionally, Rye leaves decompose quickly, which helps to break down organic matter and improve the soil’s fertility. Sorghum is a cereal grain that can be used as a cover crop for raised beds. This plant can grow quickly, suppressing weeds while providing a protective surface over the soil. Sorghum can also provide nitrogen to the soil through its decomposing biomass.

Mustard

The Mustard plant produces seeds that can be dried and used as a spice. Mustard is also known for its strong taste and yellow flowers. Mustard can be grown on various soils but prefers well-drained soils with high fertility. It should be planted in early spring before the soil becomes too dry or cold to work. After planting, water the plant regularly until it begins to grow upright. Once the plant has reached full height, stop watering it entirely and allow it to go dormant for three weeks.

During this time, the roots will die down so that new plants will form next year. When replanting in the fall, choose a younger seedling instead of an older one because old plants produce thicker pods which may not cook well when used as spices. Mustard can be harvested throughout the growing season by cutting the top off the pod with a knife or shears and then pulling out the seeds.

Scarlet Runner Beans

Scarlet Runner Beans are well suited for raised bed cultivation because they grow quickly and provide plants with nitrogen, phosphorus, and other nutrients. Scarlet Runner Beans can be planted in early spring or late fall and should be rotated with other cover crops to prevent them from becoming dominant.

Barley

Barley is a cool-season cereal crop that is versatile and easy to grow. It is tolerant to various soils and climatic conditions, making it a good choice for raised beds. Plant early in the season to get the best germination rate. In late summer or fall, begin tilling the soil to break up clods and tilth. This will improve drainage and help prevent damping-off diseases.

You can grow them collectively using strip cropping or intercropping techniques. Either way, make sure the plants are well watered during dry periods. Barley is a great cover crop for raised beds because it can provide soil protection and organic matter. It’s also a fast grower, so you can keep your bed covered quickly.

Wheat

Many different cover crops can help protect soil and prevent erosion. Wheat is one of the most common cover crops and is a good choice for raised beds because it is fast-growing, tolerant of a wide range of soils and conditions, and produces high yields. Wheat can be planted as early as late winter or early spring in regions where freezing temperatures are not a problem. It should be planted 2-3 inches deep and covered with 2-4 inches of soil. After flowering, the Wheat should be cut down to about 1 foot tall to prevent it from competing with other plants for nutrients.

Alfalfa

Alfalfa is a versatile cover crop in many different soil types and climates. It tolerates dry and wet conditions, making it a good choice for raised beds. Alfalfa can be planted in early spring or fall and grow until the first frost. It produces an abundance of hay, which can be used as feed for livestock or sold as fertilizer. Selecting the suitable variety for your climate and soil type is essential to reap the benefits of Alfalfa as a cover crop. Ensure to till the soil well before planting to break up any stubborn roots and increase airflow through the plant canopy.

Clover

Several cover crops can be grown in raised beds, and each has benefits. Clover is an excellent plant to use as a cover crop because it is functional both as a food source for wildlife and as a nitrogen fixer. Additionally, Clover can help reduce soil erosion and improve the soil’s overall health. Choose a suitable variety for your climate and location. Each has different flowering times and needs, so choose the right one for your area. Prepare the ground before planting by turning it over with a tiller or spading.

This will break up any compacted layers and allow the Clover to grow deep into the soil. Plant seeds 1-2 inches deep and cover them with soil using a fork or shovel—water well after planting to moisten the ground and promote healthy growth. Watch for signs of emerging plants after four weeks; they should have blooms appearing on top of their leaves. Once they’ve spent enough time growing foliage, you can begin thinning out individual plants to create a denser cover crop.
