Now that the Emerald Ash Borer has made its way to Omaha, homeowners with ash trees have an important decision to make: remove the tree, or preserve the tree. The solution isn't always simple, and we have conversations with each of our clients, taking into account each of their unique circumstances and needs. During these conversations, we find our clients' plans fall into one of these four categories:
DO NOT WAIT UNTIL YOUR TREE DIES TO REMOVE IT!
DEAD TREES ARE MORE EXPENSIVE TO REMOVE
The longer you wait to remove your tree, the higher the price tag. Healthy trees can be climbed or accessed in a straight forward manner. Dead or dying trees that have become brittle are extremely dangerous to remove and may require expensive equipment, such as a crane. That cost is passed onto the homeowner.
Oftentimes, the cost of tree removal isn't based on the tree's size alone. It is based on the tree's location and accessibility, the amount of material being hauled away, and the risk associated with removing it. Is the tree near a structure? Does the tree pose a great-than-average risk to the workers removing it?
SAVE MONEY; SAVE A TREE CARE WORKER
Tree removal is a risky business. In 2016 alone, 92 fatalities were reported to the Tree Care Industry Association. This number has increased every year since 2013, and it is no coincidence that as EAB sweeps across the U.S., dead and dying ash trees are changing the scene and increasing risk for tree care companies and their workers.
This risk is not limited to the tree care company - it could extend to the homeowner, as well. That's why it is ESSENTIAL that the tree care company you hire carries liability insurance AND worker's compensation insurance, so that if an injury or fatality were to occur, you are protected. Always ask to see current insurance certificates before hiring a tree care company, and understand that a company providing a low-ball bid may not be adequately covered by insurance. If you are collecting bids and one is significantly lower than the others, consider it a red flag and ask questions.
WATCH FOR CANOPY DIE-BACK
Our Treatment Method
Arbor Aesthetics uses a macro injection system to flush iron (and/or manganese, depending on the species) directly through your tree's vascular system via injection sites at the root flare. These treatments are performed in the fall and can provide up to three years of green, happy leaves for your tree!
Mulch is a useful tool that benefits and beautifies your landscape in many ways, but you need to make sure you're installing it correctly in order for plants to reap those benefits instead of suffer. Unfortunately, many landscaping companies install "mulch volcanos," and we see so many instances of these around town that it's practically burned into our minds as the correct way to do it! WRONG! Some might find these volcanos to be visually appealing, but boy do they make us arborists cringe!
Watch out for scammers!
The Tree Care Industry Association offers the following suggestions to prevent tree damage:

We received a call today from someone trying to install pavers under a silver maple tree. If you own a silver maple, you know these trees produce some mean surface roots! He asked if chopping up these roots to make room for the pavers would harm the tree. We're so glad he asked! The short answer is "YES!" Here's why:
Roots serve two purposes:
Are pavers a good solution to my problem?
What's the best alternative to pavers or river rock?
Interestingly, severe symptoms of BOB have been observed only on Quercus macrocarpa var. oliviformis, a variety of bur oak that produces smaller acorns. BOB occurs primarily on naturally established trees, and especially on mature trees on upland sites that appear to be remnants of savannah forests.
What are the symptoms?
If you suspect BOB has paid you a visit, it's time to call an arborist. We will come assess the damage and check for any secondary infections, then prescribe a fungicidal treatment plan (leaf sprays and/or trunk injection) to treat the infection. These treatments will need to be administered in the spring (May or June) to reduce the effects of BOB in the later summer.
