Tree care: Arboriculture

Life would not be possible without trees!  There are volumes written about trees but we still know very little.  Tree beauty and preservation are my central concern!


Climate Change. Summer drought conditions are becoming the norm in the Puget Sound trough.  Many of our planted trees were not established with such heat and lack of water.  During some heat waves, the night temperatures are not dropping low enough to stop trees respirating so that they are beginning the following day with a water deficit.  Steps you can take:

  • Deep watering near the tree stem and along the drip line, particularly when May and June months are hot, just after leaf-out
  • Arbor-chip mulch placed around the tree stem to a height of 4″ and forming a ring, the larger the better, and working mulch into moist soils will improve moisture retention
  • Give me a call, and I can offer advice to mitigate the situation

  • Pruning – thinning, restoring, training moderate height trees
  • Planting – providing tree species recommendations for the site, site prep and planting (planting demonstrations available)
