Tree Health Management

Trees need regular checkups, just like people. Preventive care keeps your trees healthy, strong, and looking beautiful. If you forgo tree health management, your tree could become sick and die. 

Our tree experts can perform a soil analysis to identify nutrient deficiencies and inspect your tree for signs of pests and disease. We also offer low-impact systemic injections to wipe out pests without damaging your beloved trees.

Tree Risk Assessments

You have a tree on your property that has stood strong for generations. Lately, it has looked worse for wear. Branches are beginning to crack, and you worry one might fall on you or your house. 

We can inspect your tree and determine whether it requires removal. If you wish to keep the tree, we may recommend risk mitigation solutions, such as adding cabling and bracing for structural support.

Tree Removal

Got a pesky tree that’s tearing up your driveway or growing into power lines? This could be a serious hazard, so it’s wise to remove it before someone gets hurt on your property. 

In Mercer Island, a permit is required to remove trees in most cases (the city makes an exception for small trees and dangerous trees that pose an immediate safety risk). When you hire us for tree removal work, we can help fill out the tree removal permit application on your behalf.

Tree Pruning and Trimming

Large trees might look majestic, but you can’t let their branches grow unchecked. Unhealthy branches are targets for pests and diseases. On top of that, they can fall and injure passersby. 

We recommend pruning your trees every one to five years, depending on the species. Here’s how to know if you need tree trimming: 

  • The tree is lopsided or overgrown. 
  • Branches are hitting your house or power lines. 
  • Branches are rotting and decaying. 
  • Branches are infested with pests or diseases and don’t respond to treatment.

Arborist Services

When you need expert tree care advice, reach out to our ISA Certified Arborists. They can: 

  • Assess the health of your trees 
  • Create a species profile for each tree on your property and give species-specific recommendations on potential problems and care 
  • Advise you on the protected status of your trees 
  • Provide an aerial map of your property to identify environmentally critical areas 


Insect and Disease Control

Insects and diseases are a huge nuisance for Mercer Island homeowners, especially in the balmy summer months. Although you can buy treatments at your local big-box store, these often aren’t enough to wipe out serious infestations. Plus, some of them can even make the problem worse. 

We offer thorough inspections and diagnosis, insect pest management and tree disease prevention services, and regular maintenance programs to keep your precious trees healthy for years.

Tree and Shrub Fertilization

Are your trees and shrubs yellowing or stunted? This is a surefire sign that they need fertilizer. We can perform a soil test to determine which nutrients your trees need, then deliver them where they count with deep root fertilization.

Seattle Tree Care successfully removed a large western white pine from my garden, which showed a rapid decline this past summer. A crane was used, which was the best option given placement and the need to protect fragile landscaping below. I very much appreciated the attention to detail throughout the process, such as outrigger placement and precautions taken to protect my driveway from damage.

This team did a great job pruning our strawberry trees on a difficult slope. They also started treating the white fly infestation of the same trees last autumn and just did a follow-up treatment this spring. They are reliable and amiable, in addition to being professionals who appear to be truly happy with their profession.
