Catch and Cover Crop Seeds

UK catch and cover crops are quick-growing seeds that are planted between two regular crops grown in consecutive seasons, or between two rows of regular crops in the same season. Clover seed cover crops are planted between main crops to provide many benefits for soil, such as preventing leaching, reducing soil erosion, and introducing green manure.

Smart Seeds is the UK’s leading seller of catch crops and cover seeds, and our game cover crop mixes are specially designed and hand-picked with green manure content, which provides many benefits, including the following:

  • Aids weed suppression - Since catch and cover crop mixes grow quickly, their leaves cover weeds and keep moisture in your soil. However, we do not wholly recommend that you rely on UK catch and cover crops to suppress weeds if your soil isn’t weed-free before you plant cover crops or clover seeds.
  • Protects soil - Our fast-growing cover crops help to protect your soil from extreme weather conditions such as frost, heavy rainfall or large doses of sun and wind that could occur in the UK. Catch and cover crops ensure that soil consistently maintains the optimal level of moisture.
  • Acts as pest control - The damp cover of green manure cover crops can attract frogs and beetles that feed on pests like slugs and snails, keeping them away from your soil. 
  • Fixes nitrogen levels - Nitrogen-fixing cover crop plants will emit nitrogen into the air when they die, which helps neighbouring plants survive. 

Choosing the Right Catch and Cover Crop Seed 

Here at Smart Seeds, we offer an extensive range of catch and cover crop seeds. This includes the sought-after phacelia cover crop and red clover cover crop seeds. Our team of specialists carefully develop a large and diverse range of catch and cover crop seed products for soil protection, and game cover crops which provide warm cover for arable land during the winter.
