Healthy trees with a robust trunk, vibrant leaves, sturdy branches, and vigorous roots beautify the yard and likely increase the value of your property. However, diseased and disheveled trees can do quite the opposite. It is easy to look at a tree and sense that something is off, but understanding the actual problem is the first step toward healing a diseased tree. Hiring an ISA-certified arborist from the experts at Sesmas Tree Service can resolve your problem, but we have put together this article for those who like to tackle issues on their own. This is a short list of signs of common tree diseases.

It is perfectly normal to see leaves turn orange or red during the fall season, but orange or reddish spots on tree leaves during other seasons can indicate leaf rust. There are thousands of species of rust on plants, but leaf rust is a fungal disease most often found on mature plants. It starts with white, slightly raised spots beneath the leaves and these spots soon become covered with masses of reddish-orange spores. Severe infestations will cause leaf drop.

Pick off and destroy infested leaves. Rake under the plants and trees regularly to remove fallen debris. Keep leaves dry by watering in the early morning hours. Use bio-fungicides if the infestation is serious.

Gall

Abnormal wart-like growths that appear on lower branches and stems is usually gall, a common plant disease caused by airborne bacteria. The unsightly bumps vary in size and color but are typically harmless. Granted, severe gall may disrupt the flow of water and nutrients up the trunk. Young plants are vulnerable.

Customer Reviews

3 large Leyland Cypress trees removed near front of our home. Excellent service, professional crew, very competitive pricing for superior work! Rolando provided the initial estimate and the  follow up and was the best in terms of customer relations. I'd both use this company again AND highly recommend them.

Susan Hitchcock

This is the 2nd time we have used Sesmas Tree Service. They are a wonderful company to deal with. They were on time, professional, and very thorough. They cleaned up prior to leaving and went out of their way to protect our plants and landscaping. And they kept to their proposal with no hidden cost or add ons. Definitely a five star experience!

Gene McFadden

Wow!  I deal with tree services in my professional work and I can honestly say Sesmas is by far the most professional, best equipped, efficient, safety conscious, and communicative service I've ever encountered.  Their price was very reasonable and they even went so far as to include additional work without increasing the price.  Call them!  Now! They are very quick to respond.

Scott McLendon

We've used Sesmas several times and have always received excellent service.  Estimates are quick and easy and the crew is efficient and leaves the property clean of debris.  Recently we needed a tree removed next to a heavily landscaped area.  Sebastian went over everything with me in detail and listened to my concerns.  The crew did an excellent job in removing the tree with minimal disturbance to the surrounding area.  We are pleased and will consider them again in the future for pruning and tree removal.

Tonia Griswold

Sesmas Tree Service was amazing! I had two dead trees cut and a lot of trees that were already down on my property removed. Sebastian came out and sent the quote in writing within 24 hours. We were in the process of scheduling the service when a slot opened up sooner snd I was able to go ahead and get the work done. Everything was explained ahead of time for what to expect. The crew was very efficient and professional.  All of the work and cleanup was done in one day. I would recommend Sesmas for your tree cutting/cleanup needs.

LaDora Woods

I hired Sesmas to cut down a very tricky tree that was hanging over my house as well as a few large limbs. They did a great job and had the machinery to get the job done right.

Perry Hartman

Great experience with Sesmas. They were meticulous with my tree removal, safe and efficient. David’s communication throughout the process was much appreciated. Highly recommend!

Lindsay Ellenburg

Great experience with Sesmas Tree Service. The arborist who came out was a Board Certified Master Arborist, and you could immediately tell he knew his stuff. He took the time to explain what needed to be done, gave us clear options, and helped us feel confident from start to finish. The whole process was easy and professional. We’ll definitely use them again.

Ed Martin

In many cases, gall can be removed with pruning techniques. We recommend you hire a trained and ISA-certified arborist to handle this task if you do not have experience.

Witches Broom

No, that is not a birds nest. Witches broom can be identified by the conglomeration of twigs and branches growing from a single point. The causes of witches brooms vary from infections to parasites. Like gall, it is not necessarily harmful, but it does disrupt the aesthetic of the tree.

You can leave it alone or prune it off with care. Make sure to disinfect your tools before and after pruning to avoid spreading disease. If the cluster of twigs return, then you will want to investigate the underlying cause.
