While temperatures stay mild and cool, it is still time to plant containerized trees.
If the skies have not been providing moisture, check the ground 4-6” deep around mature trees and water if the soil is dry. Keep newly planted trees watered regularly.
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.
Renew decomposed mulch with a 2-3” layer of new mulch to diminish weeds that are beginning to grow, to keep soil temperature cool and constant and to keep mowers and trimmers at a distance.
As trees begin to leaf out, check foliage and branch tips for any signs of nutrition deficiency such as stunted growth, smaller-than-normal leaf size, poor leaf color, early leaf drop and thinning foliage. Other factors may be contributing to these symptoms. Before applying fertilizer, consult a certified arborist or Missoula County Weed District & Extension for guidance.
