Key Points:
- An ISA-Certified Arborist is the best landscape professional to provide tree healthcare, maintenance, and structural risk assessments.
- Arborists, landscapers, and lawn care providers all serve distinct purposes, and knowing the differences among them can help homeowners hire the right professional.
- Arborists respond to tree emergencies but also provide pruning, pest control, seasonal maintenance visits, and a range of other services.
Whether you need your landscape cleaned up after an intense storm or your trees inspected for bark beetles, it’s crucial to know which outdoor professional to call. Not everyone has the same expertise. For example, while many Marin County homeowners have a lawn crew or landscaper, these professionals are not trained to inspect trees for pests, diseases, and structural risks. Only a certified arborist has the qualifications for this job.
At Treemasters, all of our arborists are ISA-Certified, meaning they have received the industry’s highest level of training from the International Society of Arboriculture. We offer a full range of expert tree care services in San Rafael and surrounding service areas, providing pruning, cabling, tree removals, and more.
Let’s review the key roles within the landscape industry and why an ISA-Certified Arborist is the best choice for your tree care needs.
Who’s Who in the Landscaping Industry?
There are three key roles within the industry—an arborist, a landscaper, and a lawn care provider—each serving a distinct purpose. While their roles sometimes overlap, it’s important to understand their specific areas of focus and limitations before bringing someone on to care for your yard.
Landscaper
Landscapers design, build, and maintain outdoor spaces, such as yards, gardens, and patio areas. More than gardeners, landscapers alter and refine the structural elements of a landscape while maintaining plants.
With a primary focus on aesthetics and upkeep, their responsibilities often include:
- Planting new shrubs, flowers, and trees
- Mowing and fertilizing lawns
- Trimming hedges and shrubs
- Cleaning up debris, such as fallen twigs and branches
Not all landscapers have the same level of training and credentials. According to the California Landscape Contractors Association, for projects costing more than $1,000, a landscaper must hold a license from the Contractors State License Board. Confirm this licensing before you sign a contract with a landscaping company.
While landscapers may be knowledgeable about tree and plant health, they are not professionally trained or certified to diagnose tree issues or conduct structural risk assessments.
Lawn Care Provider
Unlike landscapers who handle the aesthetics of your entire landscape, lawn care providers focus solely on turf health and appearance. More than just mowing, these professionals offer a range of lawn-specific services. Particularly in Marin County, they may work to improve areas with clay, rocky, or compacted soil.
Their core services include:
- Putting down seed for new growth
- Fertilizing the soil to improve grass growth
- Removing weeds to keep the lawn neat
- Treating and preventing pests
When hiring a lawn care provider, it’s important to know that, given their specialization, they are not qualified to work on your property’s trees, shrubs, or other plants. Their soil assessments are limited in scope and do not account for how soil health connects to tree and plant vitality.
Arborist
Arborists are professionals in arboriculture, which is the cultivation, management, and study of trees, shrubs, and other perennial woody plants. ISA-Certified Arborists have earned certification from the International Society of Arboriculture and are required to recertify every 3 years after completing continuing education requirements.
Of the three roles, arborists offer the largest range of services related to your landscape’s health and appearance:
- Conducting tree risk assessments to ensure tree stability and property safety
- Safely removing undesired, hazardous, or dying trees
- Diagnosing tree problems and diseases
- Providing plant healthcare services such as fertilization and invasive plant management
- Pruning tree branches in hazardous positions
- Preventing pests and regional threats through proactive monitoring
Arborists have the equipment and experience necessary to provide professional tree care that accounts for your landscape’s entire ecosystem, not just one aspect.
Why This Distinction Matters
An arborist is the only expert trained to deliver long-term tree healthcare. This matters most when safety concerns arise.
Imagine if one of your trees’ branches is hanging over your fence. While a landscaper might attempt to trim back the branch, an arborist has been trained in proper pruning techniques and will ensure the tree’s health and structure are considered, mitigating future threats from neighboring branches. There is a distinction between tree trimming and pruning: Trimming focuses on shape and aesthetics, while pruning aims to improve the tree’s health and structure by removing damaged or dangerous branches.
Another example is soil care. While lawn care providers can fertilize and share insights about the health of your soil, they may not be able to provide a complete picture the way an arborist can. Soil health provides the foundation for tree and plant health. Working with a specialist who can assess every component of your landscape—both individually and as part of the whole—enables a better understanding and more accurate treatment plans.
When to Call an Arborist
Most homeowners call a local arborist for emergencies, such as storm damage. However, arborists can also provide regular maintenance visits, preventive treatments, and more. Here’s when you’ll want to call an arborist over another landscape professional:
- Tree Symptoms: From summer droughts to winter storms, Bay Area trees can face significant seasonal stress, making them vulnerable to pests, diseases, and damage. If you have oak trees, keep an eye out for trunk cankers, leaf wilting, and canopy dieback, which may indicate sudden oak death. Bark cracking and peeling, oozing resin, and premature leaf drop are also signs of a problem that a certified arborist can diagnose.
- Safety Hazards: Leaning and exposed roots are signs of instability that an arborist looks for during a tree risk assessment. They can also prune branches too close to the home or power lines.
- Consultation for Removal: From safety hazards to aesthetic concerns, a certified arborist will assess your needs and manage the tree removal process from start to finish.
- Seasonal Maintenance: When an arborist visits your property every few months, they are more likely to catch early warning signs and take action before issues develop. This also means a decreased risk of tree emergencies in the future.

FAQs
Can a landscaper in Marin County remove or prune my trees?
No, these tasks must be done by a certified arborist. While landscapers can tidy up debris and perform basic trimming for aesthetics, they are not trained or certified to handle structural pruning, hazardous branch removal, or tree risk assessments. For any service that affects the health and structure of your trees, an ISA-Certified Arborist has the qualifications and certifications necessary to deliver safe, expert care.
How do I know if my tree needs an arborist vs. a lawn care provider?
If you have a tree concern, you likely need an arborist. Lawn care providers can address issues pertaining to your turf, weeds, or grass growth. If you notice bark cracking, leaning trunks, canopy dieback, oozing resin, or any sign of disease or structural instability, those are tree-specific issues that require an arborist’s diagnosis. ISA-Certified Arborists are qualified to conduct tree risk assessments, hold a pesticide applicator license, and meet a 3-year certification renewal requirement.
How often should I schedule arborist visits for routine tree maintenance?
Most tree care professionals recommend seasonal check-ins every few months to catch early warning signs, which are not always visible to the untrained eye. Regular visits from a local arborist are especially important for Bay Area properties, where seasonal droughts, storms, and regional pests like bark beetles can put significant stress on trees year-round.
What tree services are available for emergency situations in the Bay Area?
Certified arborists can respond to urgent situations such as storm-damaged limbs, uprooted trees, or branches threatening power lines or structures. While the exact service varies depending on the situation, arborists may provide pruning, cabling, tree removals, and other necessary services that address hazards quickly and safely. In Marin, Sonoma, and many surrounding counties, the Treemasters team offers 24/7 emergency tree care.
