Why Buy this product?

  • Yellow Rattle also known as Hay Rattle, is an essential ingredient for wildflower meadows
  • It suppresses grass growth and creates a more open plant sward for greater wildflower results (semi-parasitic plant thats classed as root hemiparasite. It attaches to grass, legume and vigorous wildflower root systems - dependent on these plants for essential minerals and carbohydrates) 
  • Can reduce grass/hay yields by upto 50%!
  • Great to sow in new grass/wildflower meadows or sow into existing meadows.
  • For best results into existing areas, sow on low-medium fertility soils and without ryegrass and broad grasses. Cut or graze the area as low as possible, expose as much soil as possible by harrowing or raking or with stock. Sow and roll creating a good seed to soil contact
