Why Is My Leyland Cypress Turning Brown?


Leyland cypress trees are known for their fast growing nature and the privacy screen they provide. They are very hardy and tolerant to drought, however they are not susceptible to pests or diseases. A very common disease that has been affecting many leyland cypress trees in the area is called Seiridium and Botryosphaeria canker.

What is Seiridium and Botryosphaeria canker?

Much like a common virus, this disease is quickly spread and needs to be stopped at the first sight. These diseases are both a type of fungi that affect the tree during drought or stress and eventually cause dieback on the limbs that spread to the entire tree. The very first symptoms are the yellowing off the foliage on the tree. Dark cracked areas on the bark will start to appear with small cankers as the virus progresses. Seiridium cankers will develop as small black dots and will have oozing substance similar to the resin flow found on healthy leyland cypress trees in Lilburn, Ga. Botryosphaeria cankers often appear just under the bark on the main stem but produce little to no resin.

How do I treat it?

Few things can be done without an accurate diagnostic on your trees in Lilburn, Ga. However, removing all of the limbs that are infected is the first step. When removing these limbs, make sure they are kept far away from the other trees and disposed of properly.

What Type of Oak Tree Do I Have?

Georgia’s state tree is a live oak for good reason! All different types of live oak trees populate this area heavily. Oak trees have about 450 different species, with over 20 of them being native to Georgia. We have listed out a five different types of the most commonly seen oak trees in this area.

White Oak (Quercus Alba)


Towering at 65-85 feet, the white oak is one of the most popular trees in the area. This tree is specifically used in boat building due to its rot resistance and durability. Showy fall foliage gives this one its personality turning red to orange in the fall. These trees can only be transplanted when they are very young due to the deep tap root that penetrates deep into the soil. Cutting this might forfeit the tree altogether.

Southern Red Oak (Quercus Falcata)


Slightly larger than the White Oak, the Southern Red is another favorite species of Georgia, making its way to 115-125ft tall. It has 7-11 waxy lobes on its leaves, making it easily distinguishable. It prefers full sun in the Georgia heat so it would be a great shade tree to plant in bare areas. It tolerates drought however, mulching at the base and regular watering are preferred.

Willow Oak (Quercus Phellos)


Streams and rivers are the common residence for this type as it requires lots of water and good drainage to thrive. This medium sized tree is uniquely distinguished from other oaks because of its long pencil leaves. The fruit of this tree are small acorns, providing food for birds, squirrels and other animals.

Pin Oak (Quercus Palustris)

Fast growing, easy transplant and pollution tolerance, this tree is a favorite for neighborhoods all over the area. It’s not picky with the type of soil its planted in either and can adapt well to any environment. Their wood is very heavy and often used in general construction and for firewood.

Water Oak (Quercus Nigra)


This tree is commonly identified by its spatula shaped leaves and smooth, brown bark. This provides a great shade tree or ornamental because of its spreading canopy. Like all other oaks, it has a very fast growth rate and adapts well to any type of soil.

Live Oak (Quercus Virginiana)


Last but not least, Georgia’s state tree is a Live Oak, commonly found on the coast near Savannah and surrounding areas. This beautiful tree has a root system that runs for miles, yes, MILES and is very adaptable. Covered in spanish moss, these trees provide a number of benefits from aesthetics to shade.

Signs Your Tree Is Under Stress

Most trees that have reached maturity will be fairly easy to care for an require minimum maintenance. However, other factors can also come into play. If you have noticed any of the following signs or symptoms of stress on your trees in Stone Mountain, Ga. be sure to call a Certified Arborist at North American Tree Service to schedule a free estimate for your trees before it is too late! Here are a few signs to look out for:

Dropping Limbs

Limb dropping is a very common thing that could be from either a poor pruning job that resulted in the limbs not healing properly to form strong bonds, internal tree problems such as bacterial wetwood or just part of that specific tree’s nature. River birch trees for example are known to drop large limbs and branches year round without any cause or explanation. However, more often than not, a tree that is dropping limbs in Stone Mountain, Ga. is a definite cause for worry and should be assessed by an Arborist at North American Tree Service as soon as possible.

Yellowing/Dropping Leaves

Overwatering or drought are the most common causes of the trees dropping leaves. This could also be a nutrient deficiency in the soil. When you call North American Tree Service, we can perform soil test in Stone Mountain, Ga. and determine if the soil is causing a problem for the tree and if any nutrients need to be added.

Slimy Discharge

Improper pruning cuts leave your trees exposed to all types of damage including pests and slime flux. This bacterial deisease causes sap to ooze from the wound. If this has already infected you trees, its best to call a Certified Arborist as soon as possible to assess the damage and give you a treatment plan.

Peeling Bark

Trees will naturally exfoliate themselves and rid the dead layers as it grows. However disease, insect and animal fungus are the most common reasons for peeling bark. These are usually the last stages of tree decline, meaning the tree most likely will not be able to be saved at this point. However, one of our certified Arborist’s will be able to determine how far along the decay has actually gone and if the tree can be saved or not.

Ants Around The Trunk

Carpenter ants only nest and feed on decayed wood, meaning there could be a much larger problem with the tree. The actual decay of the tree could be caused by a number of factors including drought, environmental stress, disease etc. This could be determined at the time of the estimate by one of our certified Arborists at North American Tree Service.

Mushrooms Near The Base

Honey fungus is a deadly fungi that attacks a trees root system and causes decline. Signs of honey fungi are flat top, yellow-brown mushrooms near the base of your trees. These are usually cause by overwatering since mushrooms and other fungi thrive in extremely wet conditions. Not performing proper prunes on your dead and diseased limbs can also cause the invasion of this fungi. If you notice this fungi growing on your property in Stone Mountain, Ga. be sure to call a Certified Aborist from North American Tree Service to assess the other trees and plants around it, as this disease is easily spread.

What Is Causing The Bumps On My Tree?

Have you been noticing abnormal growths on the trunk and branches of your trees? They could be galls, which are simply abnormal growths that occur on leaves, twigs, or branches. Identifying which type, however could pose a difficulty to someone who is not a certified Arborist as there are over 1500 different gall producers. Not all of these are cause by disease, however most of them are cause by insects and mites. The actual gall itself is produced by the tree in response to the egg-laying of mites and other insects on the tree. As the insects lay these eggs, they begin the process of plant growth hormones that produce abnormal cell growth, hence the galls.

Just as a fungus, galls come in all different shapes, sizes and colors. These large growths can be disturbing to look at, however usually do not pose a threat on the tree. However, there are a few different diseases that are very harmful and could potentially kill the tree, such as black knot galls and Fusiform rust galls.

Types of Unharmful Galls

Leaf Galls - You may have noticed irregular bumps on a leaf and thought they were carrying insect larvae, as it appears. In fact, by the time you have noticed these bumps these insects have moved on. They are just the result of the feeding of insects or mites, spiking this bumpy response from the leaf. As these protrusions aren’t pretty and might look harmful it is best to just let them be. If you notice them year after year this might signal a spraying is needed to keep the insects away.

Oak Galls - There are a number of different types of oak galls including:

  • Oak Apple Galls

  • Oak Bullet Galls

  • Wooly Oak Leaf Gall

  • Horned Oak Galls

  • Jumping Oak Galls

All of these are different sizes, shapes and colors and can be caused by different hosts. The good news is none of these will seriously infect your well established trees. If the trees are heavily infected by these galls, the most damage you might notice is some leaf drop or stem deformities.

Types of Harmful Galls

Black Knot Galls - primarily only infect plum and cherry trees but can also affect other fruit trees such as apricots and peaches. Black knot can be managed by a certified Arborist with some heavy pruning and disposal of the fungus it self but does not guarantee its survival.


Fusiform Rust - This specific disease is usually exclusive to Loblolly and slash pine trees but Oak trees are the alternate host. It has spindle shaped lumps and produces orange spores in the spring and is spread by the wind in March & April. Willow, laurel, and water oaks are especially at risk at this time because they are producing new leaves that the wind blown spores are drawn to. This fungus will not kill the tree immediately, in fact, the fungus can continue to grow for many many years beforehand.



If you have noticed any of these symptoms on your trees in Watkinsville, it is best to contact a Certified Arborist for a free assessment and disease diagnostic. These are typically free and could potentially save your beloved tree. At North American Tree Service we typically recommend heavy pruning of the area, if possible followed by a spray regiment to keep the tree healthy. Call us today for a free estimate!

Why it's Important to Hire Licensed & Insured Tree Service



In the tree care industry it is easy to mistake a reputable company for one that has all of its certifications, and is also licensed and insured. It is important to carefully select the company that will be working on your property because if they are not insured, you could be liable for any damage or injuries that occur on your property. Some homeowners are just looking to save a couple bucks by paying the less reputable companies cash, however they quickly find out it ends up being much more expensive.

Unnecessary Removals

In addition to the risk of being liable for any injuries and damages, the lower scale tree companies will not have as much experience or the resources as the higher level companies. Having a certified Arborist on staff is also a very important thing that homeowners should consider while choosing the right company. If a company’s sales team has no background in tree service or tree care, how would they even be able to properly diagnose your beloved trees? Unfortunately, it there has been many instances that we have arrived to an estimate only to find hundreds of trees that are alive and well marked up with orange paint signaling the removal. Every day companies of all kinds go out to estimates and tell homeowners trees should be removed just to pocket the money. This is simply unjust. Saving the tree is always our priority. Removals only occur based on the homeowners preference or if the tree is completely dead and cannot be healed.

So how can you protect yourself and your home?


An insurance certificate dated for a full year of coverage can be easily obtained with one down payment.  Don’t settle for a piece of paper.  Call the insurance company directly to verify CURRENT coverage.  Liability and especially worker’s compensation insurance in the tree care industry is very expensive.  It is also required by law.  This is the dividing line between a professional tree service company and a “fly-by-night” operator.  An uninsured tree care company often provides the lowest estimate, but at what cost to you as the homeowner?


Ask for a list of references from local satisfied customers and BE SURE TO CALL. 



Tree trimming and removal involves the use of chainsaws and chippers and is extremely dangerous.  Ask about the use of safety equipment (hardhats, chaps, safety glasses, etc.).  What are their policies about drugs in the workplace?  Ask for and verify professional affiliations the company might have, such as membership in the International Society of Arboriculture (ISA) (toll free 1-888-472-8733) or the Better Business Bureau.   


Disreputable companies tend to:

  • Solicit work door-to-door.

  • Sell jobs without producing a written estimate or work order.

  • Offer prices good only for immediate service.

  • Demand payment in advance.

There are many different credentials a company can carry to prove their dedication to providing safe and effective tree care, some of these are listed below:

  • TCIA Members - TCIA (Tree Care Industry Association) is a respectable accredidation program that requires companies and employees to carry a certain set of standards through tree care to become members. They are dedicated to educating homeowners of the proper care of trees and training employees to incorporate safe business practices. They have been striving to improve the tree care industry since 1983.

  • ISA Certified Arborist’s - To become an ISA Certified Aborist, you must be extremely knowledgeable in every area of arboriculture. You must also have a minimum of three years work experience in the industry, as well as a degree pertaining to any field of arboriculture. To be ISA Certified, you must take a very long extensive test that requires dedication and months of studying.

At North American Tree Service, we have been licensed and insured with workers compensation since we started back in the 90’s. We have a staff of certified Arborist’s who can properly diagnose and treat your trees the correct way. We have always put the homeowner and our employee’s safety first, as this is a very dangerous line of business. Our employees and customers feel safe knowing that if any injuries happen while on site, everything will be completely covered by us.
