How To Properly Put Mulch Around Your Trees

mulch around trees

  1. Remove grass, debris, sticks, and weeds from the desired diameter around the tree. The mulch should extend to the drip line of the tree
  2. Choose a color and type of mulch
  3. Rake the area around the tree so that it is an even surface
  4. Pour wood chips or bark pieces 2-4 inches deep, evenly around the circle so that it does not suffocate the tree
  5. Keep the mulch about 2 inches from the trunk of the tree so that they do not touch. When mulch covers the tree bark, it can suffocate the tree and cause it to rot.

If there is already old mulch around your trees, you should rake through it every once in awhile to make sure that it is not matted down. If it is beyond raking through, you should remove it all and follow the process above. You should replenish your mulch at least once a year to ensure it is protecting your trees and doesn’t grow mold.
