Highly effective in controlling dormant insects and their eggs.

  • Efficient – yearlong insect protection
  • Environmentally Friendly – targets only harmful insects, leaving the
    ecosystem intact
  • Pocket Book Friendly – only one application is necessary
  • Save Money: Whether you pay for city water or spend electricity running a
    pump, the money you save over time will more than pay for the rain sensor!
  • Prolonging the Life of Your Irrigation System: A rain sensor can reduce wear
    to your system because it runs only when necessary.
  • Reducing Nutrient Loss & Disease Damage: Over-watering causes nutrients
    to wash away from turf, requiring increased applications of fertilizer. It also
    retards deep root growth and increases lawn susceptibility to disease. In fact,
    over-watering has been called the most common cause of disease in turf.
  • Conserving Municipal Water: By preventing unnecessary irrigation after rain
    events, rain sensors help ensure water availability for emergencies, such as
    firefighting, especially during the peak summer months.
  • 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
  • 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
  • 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.
  • 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

    invasive species and helps bolster the wild native plant populations keeping our ecosystem balanced!

What is Forest Spokane?

The Forest Spokane Initiative is an ambitious plan to mitigate stormwater by implementing green infrastructure, namely planting trees, vegetation and remove impervious surfaces. Green infrastructure is an approach to water management that protects, restores, or mimics the natural environment. Green infrastructure is effective, economical, and enhances community safety and quality of life.

The Initiative is focusing its efforts by working with three primary groups:

  • City Departments – Integrate and maximize tree planting efforts through on-going programs and projects.
  • Community Partners – Seek community partners who have likeminded goals and objectives.
  • Neighborhoods – Implement programs and projects by working directly with Neighborhood Council’s and residents.

Programs & Project Integration:

  • Neighborhood Greening Grants – Grant funding available to local neighborhoods to plant trees and perennial vegetation.
  • Residential Tree Program – Offer 2,000 free trees to residents through two events.
  • Community Development Block Grant (CDBG) – Assist neighborhoods in utilizing funding that they have designated to street trees.
  • Capital Improvement Projects – Integrate and maximize efforts to plant tree and other perennial vegetation across the city. Projects include:
    • Sidewalk improvements
    • Street alignment, resurfacing…etc.
    • Park Improvements
    • Combined Sewer Overflow Sites
    • Trails
  • Native Tree Seedling Plantings – work with local community partners to identify and plant native tree seedlings through community volunteer events.

Greenleaf is has committed to donating 300 mature trees as a part of this program. To see our flyer, click here: GL Forest Spokane Details

ISA_logoBenefits 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.
