Flowering Weed-suppressive Ground Covers

Do you have a difficult spot in your yard where it’s challenging to grow attractive plants?  Perhaps a low to mid-height flowering groundcover will help! Read more here– Weed Suppressive Ground Covers (cornell.edu)

Tough weed suppressors require minimal maintenance but do require basic preparation for a successful outcome.

  • Start in a clean, weed-free spot. Use a hoe to dig out any perennial weed roots. These plants can push out any weeds germinating from seed, but may not compete well with deeper weed roots.
  • Till in some organic matter (compost is best) to help sandy or clay soils.
  • Add 2-4 inches mulch between plants while they are young and getting established.
  • Soak well at planting and keep moist until established in their new home.
  • While groundcover is filling in, hand weed or gently hoe around the new plants.
  • To discourage encroachment, mulch borders.
