Frequently Asked Questions

General Questions

What is an arborist?

An arborist is a certified and trained professional who specializes in improving and sustaining the health and appearance of individual trees and shrubs. An arborist understands and appreciates the value of trees and shrubs and is trained to inspect them effectively to identify causes of plant problems. An arborist is also a skilled technician who can plant trees and shrubs, treat to resolve or prevent damage, remove trees and shrubs and operate trade-specific equipment and tools.

The most competent arborists receive certification by the International Society of Arboriculture (ISA), an international professional organization that promotes the professional practice of arboriculture through research, technology, and education.

Don’t landscaping companies provide tree care?

Using one company may be convenient, but often it is at the expense of quality, depth of knowledge, reliability and professionalism. The same reason for there being many specialists in medicine applies to choosing specialist in tree care. Knowing that everything that happens to a tree or shrub stays with that plant forever, an arborist will properly treat plants even when they are small or easily reachable from the ground.

Selecting a professional arborist trained to observe subtleties in growing trees and shrubs will ensure that they are nurtured in ways that landscapers are not prepared to do. Arborists understand a tree’s or shrub’s total growing environment.

Care based on growing environments keeps trees and shrubs healthy and reduces maintenance costs. Arborists also observe trees’ growing environments. A mature sugar maple in an open mulch bed may require very different care from a similar maple growing near a home or driveway. Care based on growing environments keeps both trees and homes looking beautiful.

Plant Health Care (PHC) Questions

What is Plant Health Care (PHC)?

Plant Health Care is a total health care solution for evaluating, maintaining, identifying, and treating your trees and shrubs and their environment.

Susceptible trees and shrubs are vulnerable to attacks by pests. Some diseases can quickly and easily kill within a short period of time while others are chronic and long lasting. Some diseases cause no injuries at all. Our trained PHC technicians are trained to identify signs of disease when evaluating your trees and shrubs and will provide solutions and treatment to ensure their long-term health.

Will I need to have this service forever?

Because of the endless number of potential diseases or insect issues that can affect trees and shrubs there is a continual need for Plant Health Care. Arborists can detect and address any such issues before they become a problem that can jeopardize your trees and shrubs.

It rained about an hour after our treatment was completed.  Do I need to get it re-applied?

Most of the products we apply adhere to the foliage surface or are absorbed into the foliage within the first hour after application. If it rains within this first hour we should re-apply so that we are certain the product is effective. If it has been an hour or more since the application, we do not need to re-apply. If ever in doubt, feel free to call us for clarification.

Lawn Care Questions

We just had an application done to our lawn. How long do we need to stay off it?

We recommend that you allow the treatment to dry completely before use of the area. This may take 1-2 hours.

For granular application only, you can resume use of the treated area immediately.

Should I water my lawn in the summer?

Northern grasses are accustomed to growing in drought conditions. When water is scarce the plant will begin to shut down and go dormant, but will recover once the rains start up again.

In the event that you decide to water your lawn, do it in the early morning hours. We recommend you do not water in the evening as this has been shown to promote fungus problems. Additionally, be sure to water each area thoroughly. Place a bowl in the watering area and see how much water the area is receiving. A good thorough watering of at least an inch of water once a week is better than infrequent shallow watering. Shallow watering encourages the roots to grow to the surface instead of growing downwards.

Tree Pruning Questions

How often should I have my trees pruned?

Every three to five years is a good rule of thumb, but it could be less, depending on the tree.  Storm events may also cause damage that needs to be addressed immediately.  It’s a great idea to have our Arborist Representative evaluate your trees annually.

When is a good time to prune my trees?

It depends on what the pruning is to accomplish. Properly completed maintenance pruning, which comprises approximately 80% to 90% of the pruning necessary, can be completed at anytime of the year. It’s not so important when it’s completed, although it is critical that it be properly done. Poor pruning techniques, e.g. topping and over thinning, should never be completed regardless of the time of the year. All the remaining 10% to 20% of pruning that consists of shaping, flower and fruit production should be determined by our Arborist Representative to properly achieve the goals and outcome. With this type of pruning, timing and proper pruning procedures are most important.

How do I get grass to grow under my trees?

In natural settings, grass and trees do not coexist easily. There is not much grass in a forrest and there are not many trees in natural meadows. It is also not very healthy for the trees or the grass. If you intend to buck the natural system and try growing grass under trees, the grass will need a large amount of filtered or direct sunlight through or under the branches.

Therefore, properly and regularly pruned trees will have a better chance of growing grass under them. Be aware that it may take a while for grass to become established, and because of the growth pattern of some trees, no grass will be able to grow under them. In which case properly established and maintained mulch beds are strongly recommended.

Does pruning really provide that much of a benefit to my trees (or to me)?

Tree pruning is extremely important to help a tree develop proper branch structure so that it is less likely to suffer damage or a failure in the future.  Proper pruning can also help manage potential insect or disease issues.

Mulching Questions

Why should I mulch?

When applied correctly, mulching becomes a maintenance practice that can limit needless stress to a tree or shrub. Stressed trees or shrubs are vulnerable to infection or attack. Mulch can serve as a defensive layer that regulates moisture and temperature. Mulch can also help protect your roots in areas of heavy traffic or mowing, keeping your valuable trees and shrubs healthy.

How much mulch should do I use, and how do I apply it?

As a rule of thumb, a 2- to 4-inch layer of mulch that extends 4 to 6 feet from the base of the tree should be applied above the existing soil. Be sure to leave a one-inch gap between the base of the tree and the mulch so that the completed application resembles a doughnut.
