Even if you have never heard of Ganoderma, its odd name is probably enough to trigger red flags. In fact, Ganoderma is a type of fungus that can slowly rot and deteriorate your tree. Luckily, there are early signs that indicate Ganoderma has started its attack on your tree. Because Ganoderma can deteriorate the roots and trunk of the tree, there is a chance of the tree falling and causing property damage, injury, or worse. Call Sesmas Tree Service if you suspect your trees are infected. We are happy to run an assessment and apply treatment. Contact us today to get in touch with a friendly representative.

Ganoderma Root Rot Treatment

What Is Ganoderma?

Ganoderma is a fungus that usually develops at the base of the trunk of the tree. It thrives in humid environments and reproduces by airborne spores. New spores are dispersed throughout the summer during humid periods and infect open wounds of susceptible trees. Upon infecting main or lateral roots, the fungus develops a whitish mat under the bark, which later turns brown. The Ganoderma moves up toward the trunk to develop ribbon-like structures that form into the recognizable semicircle “conks” or shelf-like brackets at or around the base of the tree. These conks release new spores and the process repeats.

What’s the Problem?

You may have heard of Ganoderma as Reishi, a popular Eastern medicine claimed to have benefits for the immune system. However, it is nothing but bad news when it comes to your trees.

Ganoderma is a fungus that usually develops at the base of the trunk of the tree. They form “conks,” or semicircle shelves, up to 14 inches wide. However, they attack the lower heartwood and damage the structural integrity of the tree, usually resulting in windthrow. Ganoderma root rot is a devastating disease that afflicts a number of deciduous trees including maples, oaks, honeylocusts, ashes, elms, and some conifers among others.

Ganoderma root rot can significantly increase the risk of a tree falling on your house, personal property, or passersby. Call Sesmas Tree Service to get assistance on dealing with a Ganoderma infestation. Catching the signs of a Ganoderma infection early on is key if you want your trees to live a solid life.

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.

Control and Treatment of Ganoderma

If you have spotted the “conks” or fan-like mushrooms around the base or roots of your tree, then it is very likely too late to do anything. At that point, the fungus will have progressed too far and damaged the structural integrity of the tree. You should probably inspect the tree for signs of breakage and leaning and call Sesmas Tree Service to consult with an ISA-certified arborist.
However, with commitment and vigilance, you can prevent future infections:

  •   Proper planning: Choose appropriate species and cultivar to match the right tree for the site.
  •   Proper tree maintenance: Future planting, fertilizing, watering, pruning, etc. will determine the health and vigor of any tree going forward. Remember to sanitize your gardening tools!
  •   Avoid damage to tree trunks and roots: Even small wounds from mowers and trimmers can allow infection by fungi. Avoid damaging all deciduous trees, both young and old.

Call Sesmas Tree Service if would like to consider some of our maintenance services.
