Q: Why Choose a Diamond Certified tree service?

Q: Why Choose a Diamond Certified tree service?
A: Diamond Certified helps you choose a tree service with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only local tree services rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified tree contractor

Q: Why should I commit extra effort into tree care?
A: Trees have long been valued for their aesthetically pleasing qualities, which in turn can increase the value of your home. Trees can increase your home’s worth by up to 25%, depending on placement, health, size of trees, and variety. You should protect your trees with proper tree care services.

Q: Do I really need to water trees?
A: For the most part, trees need to be watered more often when they are young and growing. However, this changes if you are having drought conditions in your area. With normal rainfall levels, the main exception to this would be trees that were not suitable for your local environment.

Q: What does pruning do for trees?
A: It helps your trees stay healthier, especially as young trees grow and mature. It promotes good branch structure, that could otherwise lead to an early death of your tree.

Q: Do arborists prune trees to specific standards?
A: All arborists should follow the “ANSI A300 – part 1 pruning” standard. Ask your tree service if they always use this standard for tree pruning.

Q: What is pruning paint for trees, and is it still needed?
A: This is an out-dated procedure that used to be suggested for sealing cuts on a freshly pruned tree. Research by the US Forest Service has debunked the need for this “wound dressing”, and showed it actually was contrary to the best interests of the trees. You can even harm your trees with too much moisture.

Q: What is the best time of year to prune trees?
A: Most arborists would agree that you can prune most trees at any time it is needed. Although some trees are more likely to need pruning at the turn of different seasons such as summer of fall.

Q: Do I really need to fertilize my trees?
A: Most trees need fertilization at some point in their lives. In the forest, there are natural circumstances such as animal waste, leaves and other plant material falling to the forest floor, and other decomposition that recycles itself. Mulching is one way to help fertilize a tree, but a plant health care program from a certified arborist is best. A certified arborist can make the best determinations based on your local environment and the ground where your trees grow. This will help your trees have the best health.

Let the tree service know if you wish to employ an arborist for the long term. Whether you are a potential customer for long-term or one-time tree services, your tree care specialist or arborist should get to know your individual tree care needs so they can recommend the best services.

  • What To Ask References
    Questions for Tree Service References in Monterey County or San Benito County

    It’s best to choose a Diamond Certified tree care service because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a tree care service in Monterey County or San Benito County, you can have confidence choosing a Diamond Certified company.

    Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified tree care service company within reach, you’ll have to do your research carefully. If you do call references on your own, make sure to ask for a list of the company’s 10 most recent customers. This will help avert giving you references of only customers they know were satisfied. If you do, it’s wise to call some references provided by your tree care service.

    Keep in mind, though, that references provided to you by the tree care company are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers.

    Here are some questions you can ask tree service references in Monterey County or San Benito County:

    • What is your total satisfaction with this tree company?
    • What tree services were provided for you?
    • What reasons were you satisfied or not satisfied with these tree services?
    • Would you call this company again for your tree care in Monterey County or San Benito County?
    • Were they friendly and professional throughout your interactions?
    • Did they pressure you into tree services you did not want?
    • Did they remove trash and debris before they left?
    • Did they notify you of any accommodations required prior to starting tree work, such as moving vehicles?
    • Did your final price reflect the original estimate you were given? Why or why not? Were there any hidden costs on your final tree service invoice?

    Now That You Selected a Tree Service in Monterey County or San Benito County
    You got a written estimate based on the tree services you asked to have completed. Of course, unforeseen problems may come up. Ask for any changes of cost in writing. Let them know that you must agree to the extra costs prior to completing tree services.

    Verification of their insurance and workers’ compensation is critical, do not just take their word. You could be held liable for any damages to your home, a neighbor’s home, or any injury to tree care workers.

    Ask if there is an extra charge for travel from a tree service in Pacific Grove to complete tree care in Salinas. Sign the contract (if applicable) and do a walk-through with the senior contractor overseeing your tree work before it begins.

    Ways to Make Tree Services go Smoother
    Understand there may be extra noise and debris while the tree service completes your work. Make sure not to get close while they are completing the work, as this could be a safety hazard. Ask your tree care professional what is a safe distance to keep from the work being completed.

    Only talk to a tree care worker when they are safely on the ground. It is important to keep any pets out of the way of tree care work and to keep your windows and doors closed as much as possible. This will help avoid dust and debris from tree work getting inside your home.

Top 10 Requests
Top Service Requests for Local Tree Care Companies

The following list includes common tree care services and common problems where ISA Certified Arborists can assist:

Bracing and Cabling
Helps to provide extra support to strengthen a tree that may be weak and have limbs that may break. Without correcting a specific tree weakness, you may risk injury or property damage. This is especially problematic when there are storms.

Remove Dead Branches from Trees
A common tree issue which should be removed to increase tree health. This will also avoid property damage and injury, as dead branches are more susceptible to storm damage. You don’t want a dead tree limb or dead tree branch to fall on a car, break a window, or cause other structural damage.

Diseases in Trees / Treating Tree Diseases
Often times tree disease is the result of a deficiency of nutrition in trees. Tree disease can range from leaf discoloration, to excess bark peeling, to insect infestations.

Leaning Tree Repair
When tall trees lean at a noticeable angle, this can be a hazard if there are strong winds during storms. Leaning trees should be corrected by a professional tree service to avoid property damage or personal injuries.

Mushroom or Fungus Growth
This can happen around the base of the tree, which is a sign of tree decay. There is rotting wood in roots of trees, which means your tree is dying. A well trained arborist can assess your tree and recommend a solution.

Preventative Tree Care
Trees need proper light, pruning, and food to help it achieve a pleasing tree shape and to live longer. This includes tree fertilizers, which will increase the health and nutrition of your trees. There are both organic and conventional fertilizers for trees that your Monterey County or San Benito County tree service can provide.

Raised Earth Around Base of Trees
This can mean your tree is beginning to uproot from the ground. This could be dangerous if a strong storm came through to further uproot your tree. Many of us have seen photos of a tree that crashed on a vehicle or a tree that fell on a house.

Solar Enhancement
Solar enhancement completed by professional arborists in Monterey County or San Benito County will ensure there is sufficient light for solar panels to function adequately. If your home has solar panels in Salinas, you will see improved solar functionality by reducing the amount of shade from trees.

Tree Planting
Perhaps you wish to plant Ambrosia Pomegranate trees, apple trees, or citrus trees. Consulting a professional tree service will assist you with tree planting to maximize your investment.

View Restoration
This can include tree thinning, which creates beautiful filtered views by removing dead wood on trees. They may also perform “windowing” which creates additional open space, similar to a window’s function in your home.
