Monthly Tree Reminders: April


  • Celebrate Arbor Month!

  • Register for Run for the Trees at

  • Plant containerized and ball-and-burlap trees. Water thoroughly and mulch.

  • Check the soil moisture in tree root zones. If April’s showers are not providing enough moisture to reach tree roots, water trees.

  • Prune branches that are dead, dying, damaged and diseased. Remove vertical suckers from the crown of the tree and at the base of the tree trunk.

  • The grass is growing! Protect tree trunks from damage caused by mowers and weed trimmers with a ring of mulch or caging.

  • Keep an eye out for pests, such as aphids, and treat accordingly. For pest identification and advice, please visit Missoula County Weed District & Extension’s website at for more information.
