Tree services offered in North Bay

Cabling and bracing

Emergency tree service

In the event of an emergency situation related to your trees, Bartlett’s knowledgeable arborists are available to help you when you need it most.

Fertilization and soil care

Bartlett offers the most intensive soil management programs in the landscape industry. Before any fertilization is prescribed or performed on your property, soil samples are taken from the property and soil nutrient status is analyzed.

Insect and disease management

Bartlett Tree Experts uses an integrated approach to managing insects and diseases on your property. This begins with maintaining plant health using sound cultural practices, including pruning and creating optimal soil conditions for plant growth.

Plant analysis and diagnostics

Bartlett arborists excel at determining the cause of a plant health problem or condition, or at identifying and treating a pest infestation.

Pruning

Pruning, or tree trimming, is a practice that is periodically required on all woody landscape plants on your property. Bartlett arborists can help you with mature pruning, young pruning, or specialty pruning.

Tree inspections

During an inspection, an arborist can check the overall health of the trees, look for signs of pest and disease infestations, identify any structural problems, and determine soil requirements.

Tree removal

Tree removals are performed on your property to eliminate dead and dying trees and those that have become hazardous and cannot be mitigated by other accepted cultural practices.

Tree structure evaluation

Bartlett arborists are trained to identify symptoms of decay and other defects around your property, such as weakly attached branches, cracks, and splits, indicating imminent failure, poor architecture, dead and hanging branches, and root-related defects.

Important advice for autumn

Fertilization is the single most important proactive measure you can take in caring for your trees this season. Soil care and fertilization in autumn dramatically improve growing conditions and provide the nutrients required for vital tree root development.

8/4/2026

Don't miss these warning signs

Trees under stress display key symptoms indicating a serious problem may exist. This includes wilting or loss of leaves/needles, yellowing of leaves or browning of needles, premature autumn color, early leaf drop and sappy spots on branches. Correctly identifying the underlying cause is critical to addressing tree health issues.

7/1/2026

Summer tree threats

Summer is a time of high activity for pests as well as tree diseases caused by fungi and other organisms. Some problems may be simply aesthetic, while others can be a real threat to tree health and vitality. As such, it is important to have an arborist check your trees to determine the underlying cause.

6/1/2026

Tree care recommendations for summer

Given the stress from higher temperatures and lack of rainfall comon in summer, it is critical to water your trees and shrubs thoroughly. Applying a 3-4" layer of mulch, inspecting for pest infestations and scheduling fall fertilization can also help maintain tree health and vigor.

5/4/2026

Critical care for trees

Now is a critical time of year to prepare your trees and shrubs for the coming season. Healthy trees and shrubs are better able to withstand the higher temperatures and dry weather conditions that summer brings. Proper care can help ensure the health of your landscape plants.

Caterpillars and your trees

During spring, caterpillars and defoliating insects including California oakworm, Tussock moth and leaf tiers will emerge. We can provide effective treatments to minimize damage and help prevent a full-blown infestation.

3/6/2026

Tree problems can cause long-term damage

Now is the time to address tree health issues that are commonplace this time of year. Problems including browning on evergreen needles, damage to twigs and branches, cracks or splits in the bark and root issues should be identified in early spring, before serious damage occurs.

2/10/2026

Prepare trees for spring

After winter ends, your trees and shrubs will be working hard to establish spring growth. A soil test in early spring can help determine the precise nutrients needed for that growth, yielding a fuller canopy and vibrant, health foliage.

1/6/2026

Winter pruning

Winter is the ideal time to prune many tree species. Removal of dead or diseased branches this time of year can greatly reduce the risk they pose to your home and property. Plus, pruning can improve the overall health and appearance of your trees, getting them in shape for spring.

11/4/2025

Winter tree inspection

Colder temperatures and shorter days serve as a reminder that it’s time for your trees and shrubs to have a winter check-up. Now is the time to uncover issues such as weakly attached branches, dead wood, diseases, pest infestations and other problems before they can cause serious damage in the spring.

10/1/2025

Identifying hazardous tree conditions

As leaves fall from trees, the underlying architecture of the plant is revealed. This is the perfect opportunity to identify and correct visibly hazardous issues that can predispose trees to branch and tree failure such as dead wood and weakly attached limbs.

Schedule your winter pruning now to reduce the risk of falling branches and keep your trees looking their best!

Critical care for trees

Tree borers
