Protect the Health of Your Trees With Fertilization

Regular, professional fertilization will keep your trees strong and beautiful!

Mature trees are valuable assets - they provide shade, stability against erosion, and add beauty to our landscapes. Protecting these priceless assets is important because once you lose a mature tree, it can't be replaced.

A program of regularly scheduled, professional fertilization treatments is vital in protecting these irreplaceable resources. When you fertilize your trees, you replace necessary minerals and nutrients that are missing from the soil. Professional tree fertilization will:

  • Keep your trees lush and beautiful.
  • Prolong the life of your trees.
  • Restore the health of some sick trees.
  • Ward off pathogens - the microorganisms that can cause disease.

Why Choose Professional Tree Fertilization?

It's safer and more effective!

When in a forest, soils have nutrients galore. In our yards, that’s not often the case. As we sweep away leaves, twigs and fallen bark, we’re removing potential recycling of nutrients for the soil. Additionally, grass around our trees is unnatural and often outcompetes trees for available nutrients and water. That's why we need to fertilize.

For fertilizers to be effective, it's important they get to the roots of a tree. We use a deep root fertilization machine to deliver a blend of natural microbes and nutrients that have been formulated by a local NW Arborist specifically for northwest species. This method takes advantage of a tree's natural vascular system to deliver nutrients to the roots, wood, and canopy. Giving you the best results possible!

We also offer injections of pesticides and herbicides made of natural compounds. This injection method, beyond being more effective, is recognized as being the safe for the environment - water, soil, air, pets, and wildlife - since the treatments are injected within the tree.

When Your Tree is Sick...

They need the right medicine!

When your tree is stressed or sick, it will show it. Look for these signs:

  • Dead or broken limbs
  • Yellowish colored leaves or needles
  • Undersized leaves
  • Stunted growth or unhealthy appearance

Our certified arborist will evaluate your tree and offer suggestions for treatment options. We have been in business for 30 years. In contrast with most tree services who would suggest removal of the tree, we will offer a planned health service program to save your tree if at all possible.

Any Questions?
Common questions (and answers!) about tree fertilization.
Timing and the type of disease can affect our ability to save a sick tree. Our certified arborist will be able to diagnose your tree's condition and let you know if there are treatment options available. As with any disease, prevention by a regular program of fertilization and care is the best treatment.
Cost is determined by the number of trees and the frequency of fertilization. We will gladly give you an estimate based on our recommendations, your particular circumstances, and needs.
We provide this service for trees and also woody bushes such as rhododendrons, azaleas, hydrangeas, etc.
