The Dangers of Using Recycle Yard Mulch

It’s common practice for local tree service providers and landscaping companies to take their green waste to nearby recycling or mulching yards. Recycling yards typically charge a fraction of the cost of landfills making them the preferred choice for disposal. These tree companies get to save money while also recycling their debris and other green waste. In a perfect world where everybody did their job to the best of their abilities, this would be an ideal situation both economically and environmentally. Unfortunately, mulching and composting aren’t that simple.


The Keys to Composting

To create nutrient-rich compost, the process is time-consuming and requires special techniques, skill, and knowledge. It’s much more complicated than simply mulching some tree branches and letting them sit for a few months. Occasionally turned or static piles of mulches can take years to produce a healthy compost. And even under ideal conditions, the soonest a quality compost could be produced is about six weeks.


The most important and critical needs for composting are:


  • Water
  • Oxygen
  • Heat
  • Constant Turning


If any one of these requirements is neglected, then the compost will be compromised. The key to composting is finding the perfect balance and amount for each requirement. Too little or too much of any of these needs will result in lower quality compost. As in many “theory vs. practice” situations, the reality of composting is that it is extremely difficult to meet all the requirements necessary to produce good quality compost. This is most often where issues in the process occur, especially with recycle yards handling the mulching.

Why Recycle Yard Mulch is Dangerous

Imagine this scenario: you have a dead palm tree in your yard and you hire a local tree service company to remove the palm tree. While you may or may not know what killed the palm, you hire an arborist and they tell you the palm died due to Fusarium wilt, a common fungal disease that has no effective treatment. The infection was brought to your palm by dirty pruning tools and dirty mulch, and unfortunately, the company that you hired to remove the palm for you is the very same company that brought the disease that killed it in the first place.


The hypothetical tree service company in this common scenario wants to save money, so they take the dead and infected palm to a recycling yard for mulching instead of to a landfill, the proper place for green waste disposal. This tree service company also did not sterilize their tools after removing the dead palm tree for you. Once at the recycling yard, the infected palm tree is mulched up and mixed in with existing mulch piles. Not good!


Tree Diseases Can Spread Through Contaminated Mulch

At this point, infectious Fusarium wilt of palm fungi has now been mixed in with all of the mulch. That means yards of contaminated mulch will be spread all over the community. The fungi is further spread to any plants and trees worked on by the tree company’s contaminated tools.

Now if the mulching operation and recycle yard were careful and effective, these pathogens would be destroyed to prevent cross contamination. Unfortunately, very few mulching yards properly compost the mulch for diseases. The reason for this? It’s impossible! If you fully composted the mulch, it wouldn’t be mulch anymore and instead would be compost. These types of recycling and mulching yard companies are in the business of producing quick and easy mulch–not compost. Therefore, their business model doesn’t require the complicated and lengthy process that would kill all the pathogens before your infected palm makes its way into someone’s beautiful garden as mulch.

Hello! My name is Liriope Putnam, I am a student working on my bachelors in business management and am helping my father run his tree company. Making me a 3rd generation tree gal. My dad, Eric Putnam, and I are working together to create this blog where we will be answering common questions about trees, debunking common myths, and sharing facts on interesting topics! Our family business, Putnam Tree Service, was founded in the 1970s by my grandpa, Charles Putnam, who was a retired body builder and professional wrestler. (See Here to learn more about my grandpa) He was loved by all customers and created the culture, work ethic, and customer service practices that we still use today. As his children came of age, he began training them to be a part of the family business. Those being, Eric, Leif, Lea, and Mark. After the passing of their father, the sons went their own ways. Mark proceeded to work in construction and Leif and Eric branched off the family business and created their own. Leif went off to create Leif Putnam Tree Tech and Eric created Arbortech Consulting. After a few years, Leif too split and began his own construction company but Eric Putnam, my father, continued on the family business. Eric decided to further his studies in arboriculture and received his arborist certification in 1993. He continued to study and in 2014 he became a Board Certified Master Arborist, 1 of less than 20 in Texas and only a few hundred in the world! Holding a BCMA Certification is the peak of one’s arboriculture career. It is the highest certification, comparable to a doctorate’s degree! In fact, less than 2% of all certified arborists are Board Certified Master Arborists. Arbortech Consulting was founded in 1993, and used updated technology, practices, processes, and systems that streamlined the estimating and production process to give customers the best services efficiently for rock bottom prices whilst creating a rapport with them so we can continue to care for their trees. After what seemed like a lifetime of working in the tree industry, Eric Putnam decided to retire. In doing so, he chose to sell his company in 2018. But because he is truly passionate about what he does, his retirement didn’t last long... In fact, within a few months he began working with trees again! And in 2020, Eric went on to create another tree business named Eric Putnam BCMA, Inc. Eric Putnam BCMA, Inc. is a great improvement to the previous family business. We are dedicated to giving trees the best care possible without all of the unnecessary upselling or gimmics. We make it our mission to not only treat the trees but to help educate homeowners to understand their trees. As for me, I never saw myself being a part of the family business. I always thought I would pursue a career in medicine or engineering. In June of 2022, I graduated both high school and college with a diploma and associates degree in general studies. The following august, I moved to Orlando, Florida with my boyfriend for a year. It was there that I grew and formed a new outlook on life, and working in my family business didn’t seem like too bad of an idea anymore. In fact, I was proud to come back fulfill what I felt was my destiny. You see I come from a family of entrepreneurs, for multiple generations all of my relatives own their own small business (some have a few) and it’s almost a tradition in my family to work for your parent’s/family’s business. So, I moved back from Florida in September of 2023 and began working with my fathers company. Something that has always set our family business apart is our genuine care for the health of the trees. We have made it our mission to save trees and I am proud to have the privilege of being a part of this family company!

Trees are more than just beautiful additions to our landscapes. They offer shade, clean air, and can even help reduce stress. There are many studies in fact that prove that humans need trees, both physically and mentally. However, we live in an area that frequently experiences high winds and even hurricanes which can leave your trees set up for failure in the next big storm. However, when cared for properly there are beneficial pruning methods such as structural pruning that greatly reduce the likelihood that your tree will break in inclement weather. In this article, we’ll discuss the importance of structural pruning and provide you with some tips on how to do it properly. What is Structural Pruning? Structural pruning is the removal of branches that are structurally weak, or are growing in an undesirable direction. This technique helps to maintain the natural form of the tree while reducing the risk of damages caused by falling branches or whole tree failures in storms or high winds. Structural pruning is necessary for young trees to ensure that they develop strong branch attachments and sturdy overall structure. For mature trees, structural pruning can help to extend the life of the tree by preventing them from breaking in storms and inclement weather, thereby reducing potential stress on the tree. When To Prune Your Trees for Structure and Health - Generally speaking, the best time to prune your trees is in the winter, when above-ground plant parts have less nutrients and resources on branches and limbs, and the trees generally send many resources down into the roots during the winter. However, the long answer is a little more complicated than that, and it really depends on the species and reason for pruning. Pruning during the winter (dormant season) is also beneficial, because pests and damaging insects are less likely to be active during this period. If your tree is structurally weak, it’s really a great idea to prune before hurricane season to get your tree structurally sound, and then following up with a good pruning cycle to keep your trees well- maintained and growing in the right direction! Structurally Pruning Mature Trees – Mature trees have largely established their growth pattern by the time they reach maturity , however sometimes, because of various environmental conditions, and poor pruning techniques, they will develop unhealthy and weak attachments that need to be amended. Here are a few things to look for that could indicate a structural weakness: 1. Dead Limbs – Trees naturally “shed” dead tissue by detaching it both physically and bio- chemically from the rest of the tree. These often are the first to go in even mild winds 2. Co-dominant leads – these are leads which kind of look like twins … they are usually about the same size in diameter, originating from the same area on the branch or trunk, and are often weakly attached. 3. Weakly attached leads – wide, “U-shaped” branch unions are very strong, while narrow, “V- shaped” branch unions are often very weak and prone to failure. 4. Rubbing Limbs – whenever a limb rubs against another limb, it can blow around in the wind, scraping and damaging the living tissue within the tree. It’s important to prune these structural defects out of a tree before the damage is significant. 5. Limbs with decay – often the reason a limb fails in storms is because if has some sort of decay which weakened it. Deciduous trees with large limbs pruned off of the tops of the limb often get this decay and are quick to fall in inclement weather. Establishing Young Trees Through Pruning – When a tree is young or recently planted is generally the best time to prune a tree, since they are able to take much more pruning at this point without being overly stressed and helping them to grow in a healthy, strong manner which will cause you MUCH less future pruning and maintenance needs, and leave you with a healthy strong manor, less likely to fail in storms! There are 5 primary goals when pruning young trees; 1. Remove dead/broken/diseased tissue – obviously! 2. Select a central leader and remove competing leaders – if there were such a thing as a perfect tree, it wound have one main branch at the top, and everything branching subordinately off of that one. 3. Select limbs that will be the lowest permanent branch (s) in the canopy – keep in mind the height needs of your home and surrounding streets, landscapes, etc. 4. Select the main branches and remove or reduce competing branches/limbs – limbs spaced too closely together often form weak attachment points. 5. Select and maintain temporary branches below the lowest permanent branch – leaving these on for a while helps develop good trunk taper, building a stronger overall structure. Pruning Techniques – Before Pruning your trees or even hiring a professional Certified Arborist or Board Certified Arborist to prune your trees, it’s important to have a plan in place. Start by identifying the branches that need to be removed, focusing on weaker portions of the canopy first. The first limbs that you should look at removing are diseased or damaged branches, crossing/rubbing limbs, and those that are growing toward obstructions such as buildings or powerlines. Always make sure the tree is safe enough to prune, and, if you have to get off the ground to do the pruning, you’re way out of your league; don’t leave your loved ones behind, and hire a professional Certified Arborist or ISA Board Certified Master Arborist to do the work …. Tree care is the #1 Deadliest industry in The USA, and #3 overall deadliest industry in the world! Always use clean, sharp tools, and make your pruning wounds in a manner which allows the tree to seal/heal properly, just outside of the branch collar. Avoid tearing the bark or leaving a stub. The tree is unable to heal these wounds, and this can often lead to decay setting in, giving you potential problems for years to come! Structural pruning is an important aspect of tree care that helps to maintain the health and beauty of your trees, and keep them healthy and strong for many years to come! By structurally pruning your trees, you can help to avoid and prevent unnecessary damage caused by falling branches, both to your home/property, and your tree! Pruning is best done during the dormant season, but here in Houston it’s a good idea to help weak trees get a little stronger through structural pruning before hurricane season …. You know …. Just in case! With a good pruning program and plant healthcare program, your trees are sure to be healthy and thriving for years to come!
