Organic Lawn Fertilizer

  • Naturally builds up the soil by stimulating microbes that fight off disease
    and improves the overall health and structure of your soil
  • Contains no unnecessary or unwanted salts and chemicals like regular
  • Organic fertilizer releases slower and can last longer than regular

Organic Dormant Insect Oil

Highly effective in controlling dormant insects and their eggs.
It’s environmentally friendly too! No Pesticides!

Soil Sample Test

  • For problems with:
    • Nutrient deficiencies in plants
    • Poor plant growth and response from applied fertilizers
    • Poor quality foliage
    • Managing manure or compost applications
  • Benefits of soil sample testing include:
    • Determines nutrient levels in the soil
    • Determines pH levels (lime needs)
    • Provides a decision making tool to determine what nutrients to apply, how
      much, and when
    • Potential for higher quality turf, trees, and plants

Integrated Pest Management (IPM)

  • We practice IPM which is a more environment friendly approach to insect and
    weed control and plant health.
  • More site visits insure early detection of pest problems –
    early detection means fewer applications are needed and fewer products are used.
    As a result, predatory insects survive and the ecosystem remains balanced

Phosphate-Free Fertilizer

  • High levels of phosphorous in soil can transfer to water runoff which is
    dangerous to our local lakes and streams – phosphate-free fertilizer helps
    prevent this.
  • Phosphorous creates poor water quality that leads to algae blooms, which in
    turn can be toxic to aquatic life such as fish, frogs, etc. Phosphate-free
    fertilizer is a responsible step to eliminating unnecessary phosphate deposits
    into the environment.

Reuse and Recycle

  • We recycle wood from pruning and tree services
  • We reuse wood chips as recycled bark for shrub beds
  • We recycle yard waste from yard clean-ups and renovations
  • We recycle and/or reuse grass clippings for compost
  • Our office recycles paper, ink, bottles, glasses, batteries, and cans; we reuse the backside of paper for note-taking before we recycle it

Supply & Installation of Native Plants

  • Increasing the use of native plants in landscape design reduces the risk from
    invasive species and helps bolster the wild native plant populations keeping our ecosystem balanced!
  • Some common plants that are native to the Northwest are: Douglas Fir, Quaking
    Aspen, Vine Maple, Red Twig Dogwood, Oregon Grape, Spirea, Goldenrod, and many

Natural Pruning

  • A sustainable practice that helps maintain the health of trees, adding to
    their life span and avoiding unnecessary and costly replacement of trees and
  • Eliminates the unnecessary waste and debris caused by shearing; natural
    pruning is selectively pruning only what needs to be pruned for the health of the

Benefits of Obtaining an ISA Certification Credential

The tree care profession has experienced rapid growth over the past decade and there is a significant amount of knowledge required to perform at the highest level. ISA credentials help consumers identify qualified, knowledgeable tree care professionals.

Earning a credential is a voluntary activity, but it demonstrates that you have the proper knowledge and skills, as well as a high level of dedication to your profession and your community. ISA Certified Arborists understand the importance of continued education and how it helps to make the world be a better place, one tree at a time.


ISA credentials are valued and trusted because they let consumers know that you possess a high degree of knowledge about caring for and maintaining trees. When developing an exam, a panel of subject matter experts from around the world completes a job task analysis, and then writes an exam that encompasses the defined skills. ISA credentials build expert knowledge and reflect the professional skills sought by leaders from the public and private sectors, including training, academia and government organizations.


Earning an ISA credential has many benefits. A few of the major benefits are listed below.

  • Certification builds an individual’s self-image. By studying for and passing the exam, individuals reaffirm to themselves and their peers a thorough knowledge and dedication to arboriculture.
  • Certification affords the public and those in government the opportunity to make an informed selection of services based on the knowledge and advanced training demonstrated by an ISA Certification.
  • The process of becoming ISA Certified and maintaining the designation provides incentives to the individual to continue his or her ongoing professional development.
  • Certification is a tool to help employers in both training their personnel and selecting new employees.
  • Holding an ISA credential can lead to an increase in income and promote new opportunities in professional advancement.
  • Certification is a tool used to set oneself apart from the competition and gain a competitive edge in today’s economy.
  • Certifications, sometime more than price, can be a deciding factor when multiple individuals bid for the same job. If you want the job done right, hire the right people!

Greenleaf Landscaping always has ISA Certified Arborists on staff.
