Best Mulch for Mature Maple Trees

Recommended: Pine Straw

  • Any organic mulch works
  • Pine straw ideal: lightweight, acidic, slow decomposition
  • Apply 3 inches max
  • Donut shape: thin near trunk, thicker outward
  • Extend 3 ft from trunk

Avoid

  • Rock/gravel mulch - compacts soil, heats roots
  • Volcano mulching (piled on trunk) - causes rot
