Composting now does amazing things for your garden. Whether you’re new to gardening, or a seasoned pro, building better soil is the single most important thing you can do to improve your gardening success. And now is the best time to do it!

Adding compost before you mulch helps retain water, supports healthy plant growth, and helps plants fight diseases, pests and other stresses. So before you mulch, add a layer of compost.


  • Calculate the square footage of your flower beds. Check the compost bag to find out how much you’ll need or ask a Home Depot Garden Center associate.
  • If there’s old mulch on the flower bed, rake it away. Compost or repurpose under trees and shrubs.
  • Add a 1” layer of compost on soil, breaking up any clumps. Keep the compost off the plants.
  • Work compost into the soil. No need to dig deeply. You don’t want to uproot any plants.
  • Lightly water the compost. Soaking the soil is only necessary if it is dry.
  • Top with 2″-3” of mulch.


When you transplant or add new plants to your flower bed, mix a shovelful of compost into the soil you have dug out of the hole.
