S6 Trees

DBH= Diameter At Breast Height

When estimating tree work we use a tape measure that measures the diameter of the trunk. We have found that by using math to estimate, we take the emotion out of the formula thus treating everyone equal. We are simply able to give a good estimate based on objective results rather than bias treatment.

Structural Pruning

S6 Trees uses the skill of technical climbing with ropes to better provide quality work and maximize on overall health of the tree. We provide options of crown: cleaning, thinning, raising, reduction and restoration.

Before & After

  • Structural Pruning is described by ISA (International Society of Arboriculture) as removing broken, dead, dying or damaged branches. A dominant leader is selected where it is chosen because of its strength and vertical dominance.
  • Crown Cleaning is best described as removing selected branches that are dead, diseased, broken, or weakly attached.
  • Crown Thinning is described by ISA as the practice of crown cleaning along with removing branches to increase light penetration and air movement through the crown, thus improving overall structure. Proper thinning should still maintain natural shape and structure depending on species.
  • Crown Raising is the practice of raising lower branches to provide clearance for buildings, signs, vehicles, pedestrians and lines of sight.
  • Crown Restoration is used in fixing poorly pruned trees which were previously topped etc. It’s the removal of water sprouts, stubs and dead branches to improve overall structure and form.

Root Collar Excavation

Problems such as basal rot and girdling roots can often emerge when trees are planted incorrectly. We can help correct the stress on your trees by uncovering any hidden issues beneath the soil using our air-spade tool.


  • Many trees in urban areas suffer stress due to new construction, pedestrian traffic, and Landscape companies that fail to take the time to insure proper installation- thus they plant the trees too deep and fail to cut away anything that can later cause the tree to be girdled. Trees are always compartmentalizing, if the cambium (thin layer or sheath that later becomes the vascular system of the tree) layer is cut off- it will inhibit the nutrients and water from reaching the top of the trees- thus causing the tree to die from the top down.

Tree Ring & Bed Edging

This service adds a great look to your home or property and provides a way to minimize basal damage caused by weed eaters and mowers! This service fits well with our root collar excavation! We can either redefine an already existing edge or we can sculpt a new edge for around your tree or future bed.

Deep Root Fertilizing

S6 Trees recommends that individuals with shrubs or trees assist in their preventative health and overall vitality by using a slow release fertilizer, which can be applied once a year with the help of S6 Tree Service.

  • ISA recommends the desirable method of using a slow release fertilizer, where the nutrients (*Nitrogen, Phosphorus, Potassium) are able to be released over an extended period of time. This is best defined by being an organic fertilizer. Verses Inorganic which means the nutrients are released relatively quickly. By using a slow release, it reduces the risk of “salt and fertilizer burn” and leaching. Burn is caused by raising the osmotic potential of the soil and drawing water out of the roots; Leaching is when elements or compounds are washed down through the soil and the plant is unable to utilize much of those nutrients.
  • S6 trees uses the liquid injection (pressurized liquid) method to insure that the fertilizer is properly applied in the root zone of the tree.

Proper planting methods and staking can add longevity to your tree and provide you with a great asset to your home and family.

The steps in planting your tree

  1. Determine your zone (location) http://www.arborday.org/media/zones.cfm

By using a hardiness zone map; one can determine the type of tree species that will most likely thrive on the desired planting location. Nothing is worse than working hard to plant a tree and keeping it alive only to find out that it is dying because it was best suited for a tropical climate.

  1. Determine soil type and availability to water

You will easily tell what grows in your area if you spend some time looking around at the different trees and shrubs in your area. If you know you’re in a high plains area- and yet trying to plant a tree that requires a great deal of water to thrive in- most likely the tree will be stressed and less likely to survive. A soil filtration test (To determine if soil has more sand, clay etc in it) is an easy and cheap approach to determining how your tree will act when it is irrigated. Often times property owners fail to realize that if there is inadequate drainage due to the soil type even if the tree is suited for that area it has no chance of survival due to various rot and suffocation which will occur if the tree is not resilient to drainage problems.

We would be happy and willing to help if you have trouble determining what species of tree will be best  for your specific location.

  1. Select and purchase your tree

There are a number of different options to pick from when it comes to purchasing a tree. Not just the species of the tree but the age, container etc. You can choose from; bare root, containerized, container grown, balled and burlapped (B&B), and mature trees. The mature trees when transplanted and installed will require additional equipment and expertise. When selecting a tree we would recommend that you take time and find one that will add value to your property. Trees that grow quickly are not always the best option. Those that have great benefits and resilience to bugs etc often times take longer to mature, but in time they serve as a better investment to the home owner. http://www.treebenefits.com/calculator/index.cfm

  1. Tree planting and proper Installation

This is a very important note: A tree that is planted too deep is more prone to have problems in the future whether that is basal rot or girdling roots. It is important when receiving stock from a nursery to look at each individual tree and make a logical assessment as to how it will act in the future. When receiving trees in containers, take the time to find the root flare (collar) and make sure that it is planted level with the already existing earth. Such simple practices can make a huge difference on the survivability of the tree.

Due to improper pruning methods or mismanagement in the early stages of the trees development. Preventive measures such as cabling and bracing are highly recommended to customers desiring for their asset to be saved. Such measures are to prevent against tree failure- which can cause fatality to pedestrians or damage to a home or property.

A proper tree assessment will help us determine whether your tree requires the installation of cables and bracing rods to provide supplemental support.

When deciding whether  or not your tree needs support, it is best to understand by ISA standards, that because all trees are not the same, a proper tree assessment will help one decide whether to install supplemental support systems, prune potentially hazardous limbs, or remove the entire tree. In order for us to recommend there being a supplemental support- the root system must be sound and there cannot be any signs of basal rot.

There are two forms of support- one is a rigid support system using metal cable allowing for a static (of little or no stretch) approach; which is only used in special circumstances due to the negative effects it can have on the trees health.The other is commonly referred to, as a dynamic cabling system which has been developed as a way to allow trees to sway and have free access to move about. ISA best explains the benefits of this system as a way for the tree to produce supporting wood where needed, so in time the tree will be able to support itself rather than to rely on the actual support system.

When cabling is installed it should be done based on the physics of the overall tree- But should be installed near the upper 1/3 of the canopy.

When properly installed- this system should be inspected periodically to assure proper installation and adjustments to prevent girdling the tree.


When no other options are available to save the tree, we are equipped to handle your removals.

*Tree removal and stump grinding services are only offered to commercial properties and our membership holders- sorry for the inconvenience
