Product Details
Yellow Trefoil, also known as Black Medic, is a low-growing annual green manure that offers a wealth of benefits for your garden. This hardy plant is a natural choice for improving soil health, suppressing weeds, and retaining soil moisture during the hot summer months. It is ideal for interplanting with taller crops like tomatoes and beans, providing a protective layer that helps preserve moisture and suppress weeds. The frost also acts in your favour, as it causes Yellow Trefoil to fall back, creating a natural mulch that insulates the soil over winter.
One of the standout features of Yellow Trefoil is its ability to fix nitrogen, which improves soil fertility and supports the healthy growth of surrounding plants. This makes it an excellent choice for those looking to boost soil fertility and encourage strong plant development. Whether you’re using it as a cover crop, a mulch for winter, or a moisture-retaining ground cover for the summer, Yellow Trefoil is a true garden essential.
