The Sissoo Tree

The tree you should never have planted or have on your property…

Sissoo (Indian Ironwood) trees are listed as one of the most invasive trees of the world due to its root structure which can reach great distances from the trunk of the tree. Our customers have found roots and shoots sprouting from them up to 100′ away from the trunk. One customer had them coming up through the kitchen island around the drain pipe from the sink causing damage to the plumbing.








Gravely’s Septic Service has found Sissoo tree roots inside of septic tanks and the drain pipe leading to the septic tank. A quick call to Gravely’s by several customers confirmed that this tree should not be anywhere near a septic system due to the fact that the roots are so very aggressive and will cause $1000’s in damage to your septic system.










So why is this? The aggressive Sissoo Tree root structure is key to the plant’s survival and propagation in its native environment where it needed to establish a strong root system to survive in its native soil. Consequently, this tree is an excellent choice where soil erosion is a concern. For example, in the Phoenix freeway system where the road system is built below ground level, these trees have been planted to help secure the soil from eroding from the valleys heavy rain storms.







These are nice and shady trees if they are placed far enough away from any underground utilities or structures.

This Queen Creek Arizona Cortina community customer called their Sissoo trees, evil devil trees, like poltergeist because of the roots continuing to sprout new tree plants all over the yard after the trees were removed.  We solved this problem and permanently eliminated the possibility of the tree coming back. We use a special procedure to permanently remove the tree and the chance of the roots sprouting new trees.







This Queen Creek Arizona Cortina community customer had us remove his very large and quite beautiful Sissoo tree as its roots were intertwined with the lawn and continually damaging the irrigation system, requiring costly repairs.







This Queen Creek Arizona Cortina community customer had us remove 7 large Sissoo trees, as they were causing damage in several areas of the property. We had to remove dozens of pavers to remove the roots that were lifting the pavers and causing a dangerous trip hazard. One of the roots was 60′ away from the tree and working its way towards the pool. They have been known to penetrate the walls of the pool to get the water. Also, note the damage this root was doing to the grass border.

There are exceptions to this opinion.

More storm damage, tree removal and branch removal

And the storms continue to damage trees, houses and cars etc. lots of damage across the valley resulting in downed trees and branches needing to be removed. This branch fell about 100 feet from a neighbors eucalyptus tree damaging the patio breaking thru the roof and breaking several trusses causing severe damage to the house. Eucalyptus trees are a beautiful tree that grow fast and very big. Euc’s wood is brittle and prone to shedding its branches as stated in the article from,  As the common name implies, the wood is very brittle and is not considered useful for timber. All eucalypts have an efficient method for shedding limbs, as described by Jacobs (1955). For this reason, larger species such as E. mannifera should not be planted so that they will overhang dwellings. However, its graceful form and branching habit do make it an excellent shade or specimen tree. They are prone to breaking off branches like this when the wind picks up. This tree is a hazard to the immediate area as its branches reach into 4 separate backyards. This tree dropped 2 large and several smaller branches in the storm. We climbed and removed several broken and hanging branches, these branches were already broken off and were suspended by other branches, just hanging there ready to fall. This is a common tree for the valley, but this tree out grew its usefulness and grew into a Hazard for the residents in the four houses that surround this tree as it grew to a height of 80 feet and a diameter of  45 inches. Over the years this tree has shed many branches, some large and all are dangerous, so the owners chose to have it removed as they realized that it had turned into the wrong tree for their backyard.

Preventing Monsoon Storm tree damage

Proper tree maintenance and tree trimming is important to preventing emergency tree damage. During Monsoon storms it is the wind that causes the most storm damage to trees, often resulting in property damage in Arizona. Keeping your trees trimmed properly can prevent a fallen tree from happening in the first place. Let us assess your trees for problems and weaknesses that can be taken care of before the damage happens. Don’t wait until the storm uproots your valuable trees that took many years to grow.

Tree pruning is also beneficial to ensure your trees do not have hanging or dead limbs that pose a threat to your property. Even for a tree that is otherwise perfectly healthy, overly dense foliage poses a safety hazard during stormy weather. A dense canopy will not allow the wind to easily pass through and the resistance to wind can and will cause branches to break during a major wind/monsoon storm. Too dense of canopy can even bring the entire tree down.

FEMA (Federal Emergency Management Agency), which is a branch of the U.S. Department of Homeland Security, states that “Three-fourths of the damage that trees incur during storms is predictable and preventable.” Here are some defects to watch out for that make trees more vulnerable to wind and other severities of the weather:

Dead wood is unpredictable because it is brittle, and cannot give under pressure like living tree branches.
Cracks are clear indicators of potential branch failure, where there will be splitting sooner or later.
Poor tree composition (branch structure) is harder for the layman to identify. Look for excessive leaning, long horizontal limbs, crossing branches that rub against each other and create wounds, and narrow crotches (V-shaped instead of U-shaped). Multi-trunked trees need special attention and care. Two trunks or leaders that are of identical diameter and have a narrow crotch are not a good sign. To prevent splitting, choose one to be made dominant by stunting the growth of the other through pruning (called subordination).
Decay, as evidenced by fungal growth or hollow cavities, is a sign of weakness.
Pests, such as the Palo Verde borer, can exacerbate a tree’s health problems, but they typically target trees that are already sickly.
Root problems, such as stem-girdling roots, while sometimes harder to detect, have the most impact on a tree’s inability to stay upright. Keep in mind that roots are a tree’s anchor. If a significant portion of a mature tree’s roots have been crushed or cut or if the tree is still root-bound from the box it came in from the nursery before it was planted, you may consider removing the tree before Mother Nature removes it for you (without warning).

Weak roots and a thick canopy is the deadliest combination during a storm.

Here are a few more basic tips for avoiding storm damage:

Plant new trees with their mature size in mind. Do not plant in shallow soils, too close to buildings or wires, or in steep banks. Some trees are more brittle and susceptible to breaking.
Water, mulch, and fertilize the trees regularly and properly.
Prune annually (or every two to three years, depending on the variety) even while the trees are still young.
Proper pruning is your best bet for avoiding problems.
Avoid excavating around roots. If some excavation is necessary, take measures to minimize cutting or any other impairment of the roots.
Do not top trees! This common but incorrect practice guarantees eventual failure of branches.

Desert tree trimming and pruning in Scottsdale AZ

Desert trees, palo verde and mesquite trees are very common in residential neighborhoods and have tendency to be over grown with large canopies that grow quickly due to the abundance of water available to them. These desert plants are drought tolerant and need very little watering to survive, so when they have water available trough drip systems or irrigation they thrive and grow fast and large which can be very desirable trees.

the down side is the canopy can out grow the root structure and create an unstable situation that during high winds and monsoon storms can blow them over as this large Mesquite tree was blown over in a monsoon storm in 2015 in Mesa Arizona. This particular tree roots were intertwined and were wrapped around each other from being kept to long in its original planting bucket that you would buy it from Home Depot or Lowes. This situation is called root bound. You can see how the roots have grown into a circular pattern and did not grow outward which this large tree needed for support during windy conditions. This tree was fed by several drip systems providing it with much more water than it needed to grow healthy, consequently it took all the water it could get and grew very large, outgrowing its root structure which was already weakened by its root bound situation.

Monsoon mesquite tree

Mesquite tree pruning trimming

We had the opportunity to trim this very old Mesquite tree in Scottsdale Saturday. It was very full and had many branches that were over growing each other and one of the main leaders was up against the carport aw ning and bending the metal structure. We were going to remove this leader or branch but after further inspecting this branch was one half of the tree, so instead we reduced the weight so it would not impact the awning with as much force.

tree trimming or pruning of this wonderful tree will give it a very good chance of surviving the up and coming monsoon season.


Wood rot and insect infestation of your trees

Here are some pictures from some Ash trees that we removed. The needed tree removal for awhile now, they are over 50 years old and the wood peckers and wood carver bees severally damaged the trees which allowed termites and ants to attack the weakened condition of these once beautiful Ash trees. Herbicides, weed killers used in the lawn area also poorly affected the health of these trees. Proper care with fertilization could have saved these trees from this destruction. image image image

And more tree wind damage

Well look what we have to clean up. This tree had some weak branches that fell in the recent wind storm. These branches had weak unions attaching them to the stem of the tree. This could have been prevented with proper tree maintenance which would have been much cheaper than this removal of downed branches and now the tree as it will not survive and is structurally not sound.image

Winds do damage to trees

Yesterday’s winds caused some damage to a lot of the valleys trees. Branches were downed or broken and hanging. Trees that are not properly maintained by a tree expert can pose a hazard in these windy conditions with falling branches and in extreme condition falling trees, both can pose a serious risk. Your trees need to be protected from adverse weather conditions as they are a important part of your property which can enhance your properties value.

Tree damage due to high winds

Wow what a windy day today, the trees and palm trees were swaying in the wind. This is mothers natures way of trimming trees. It’s time to think about thinning out your trees before the monsoons come in and do it for you. Eucalyptus trees are susceptible to wind damage, now is the time to have us come out and evaluate your trees and make sure they are ready for this years monsoon season.

Tree trimming and wind storm cleanup

Well plenty of tree pruning or trimming this week. We worked on some Ficus, Ash and Mulberry trees this week that have been trimmed or topped previously by non PROFFESIONAL tree workers that were promoting themselves as experts. There are ISA and ASTM standards for proper pruning techniques and clearly this not performed on these trees from the previous workers. Please if you are considering tree trimming it is imperative to your trees health to choose someone who understands how a tree should be pruned properly to promote its health.
