Rain Delay Opportunity

North Oaks, MN Tree Service

October 11, 2019 – When it comes to inclement weather, our field team typically presses through knowing a job is to be done, but today, we took the opportunity to sit in from the first blast of freezing, snowy weather to learn more of our craft and why proper pruning cuts are paramount in any General Tree Care project. Field staff leader, Trevor Novacek is pictured here going over proper pruning cuts…where to make them and how to carry out with precision. Doing so will limit the wound impact to the tree or shrub and when performed well, the cuts heal thus minimizing risk of decay. It was a discussion between entry level staff to our most experienced arborists. The amount of knowledge under the roof this morning is staggering and is a privilege to be a part of this expert staff. For the most professional and knowledgeable tree care, contact SavATree today!

So You Have a Project?

Tree Service in North Oaks, MN

October 5, 2019 – Do you have a landscaping project coming yet this fall or planning for next spring? Are there valuable tree(s) on your landscape and, if so, is your project near the tree(s)? If you have answered yes to any of the above, please contact your SavATree arborist to help guide you through the project and tree preservation to avoid a situation as shown in the above photo. Not all landscaping and construction firms understand the importance of tree preservation in landscape or construction projects and you could find yourself in a situation like this. The customer’s White Oak was literally buried in over 12 inches of soil and our team performed Root Flare Excavation around the base of the tree and utilized the “air-spade” equipment to aerate and loosen the soil in the general area around the tree to help alleviate compaction from the equipment and the physicality of additional soil being added to the grade. This tree has an intense treatment regimen on its horizon consisting of soil enriching injections boosting microbial activity, growth regulation to encourage fine root development and bio-stimulant soil treatment(s) to curb the stress and bolster a healthier tree.

Big Trees!

Tree Removal in Circle Pines, MN

September 27, 2019 – Unfortunately, there are instances where trees have to be removed. I typically do my best to preserve and protect the trees in our urban forests, but in instances such as this, trees do you have to be removed out of safety concern. In the photo attached, we have Hal Stewart and his crew taking down a near 6 foot in diameter silver maple tree. The longstanding client became far too concerned in regards to the safety of this tree as recent storms damaged it to the point where it was deemed necessary to take down. If you have a BIG tree on your property and have concern about its structure, stability and safety, do not hesitate to contact your SavATree arborist for an inspection!

Let’s Take a Closer Look, Shall We?

September 21, 2019 – Colorado Blue Spruce trees are ubiquitous in today’s landscape. These beautiful trees are utilized for many different reasons throughout our region, but, unfortunately, as striking as they are, they do carry baggage as they often become impacted by foliar diseases. One of the most common diseases is called Rhizosphaera Needlecast. I recently took a tissue sample from a new client property and put the leaves (needles) under the microscope for a closer look. The fungal pathogen forms black globular fruiting bodies along each needle and typically the disease affects the lowest limbs first and progresses from the interior canopy, outward. I have included three photos where the first is a close up of a 3 year old needle that is fully infected with the disease. The second is a two year old needle where there is some infection, but not as populated as the first. The last photo is of this current year’s growth which is disease free and healthy thanks to our first full season of treatment. The disease cannot cure current infection but can be managed rather effectively through disease management treatments for current and future seasonal growth. If you are concerned about your Spruce tree(s) please contact your SavATree ISA Certified Arborist for an inspection.

Emerald Ash Borer (EAB) – Am I Still Safe?

emerald ash borer treatment in MN

September 1, 2019 – If you live in the mid-west, it is almost certain you have heard or read about the destructive insect ravaging our ash trees known as Emerald Ash Borer or EAB. Here in the Twin Cities, ash trees are ubiquitous along our streets, on residential and commercial properties and in our forests. When it comes down to it, ash are wonderful trees, but, even though I was not in this world at the time, I do know that history is repeating itself in respect to our highly utilized trees. Back in the 60’s and 70’s, the United States experienced a dark time where we lost countless elm trees due to a disease called Dutch Elm Disease (DED). Even thought DED has no real correlation with EAB, the issue is that so many communities relied upon the ash genera (Fraxinus sp.) to reforest our streets and properties. That was not the best plan, but at the time, no one thought not to do it because ash are a great tree that are incredibly adaptive to poor soils and harsh conditions/exposure much like our treasured American elm. Quick explanation of DED vs. EAB – Elms were affected by a disease vectored (carried) by a beetle where ash are being affected by the feeding of a beetle. Fast forward a few decades and we have our tree lined streets being decimated again by the alien species, EAB. This insect’s larvae feed ferociously and, since Ash are the only food source, damage occurs quickly! The best thing to do is to contact your SavATree arborist and he/she can help determine what plan is best to help your tree(s). It all circles around the situation, value of the tree(s) and both short/long-term goals. Treatments are very effective, but the key is to identify if your tree is a healthy candidate and, in some cases, treatment alone may not be enough where supplemental nutrient or soil enriching treatments are recommended to bolster the health of your tree while injecting to stave off EAB. This is a link from the Minnesota Dept. of Agriculture where it will show an interactive map as to where EAB has been reported and quarantined zones – Emerald Ash Borer Status. It is imperative to learn more if you have Ash on your property and contact us today!

Lawn Update: Fall Preparations

August 21, 2019 – It is so hard to comprehend that we are slowly approaching my favorite season, Fall. As we enter the last leg of summer, this is THE time to look at renovating challenging areas where turf has succumbed to summer stressors or simply looking to bolster the turf stand around your home. One of the best ways to improve turf density is a combined effort of core aeration and overseeding with our custom made seed blends in accordance to exposure, be it full sun or a shady environment. Core aeration is a cultural practice where we use lawn equipment, both walk behind and stand-on, to physically pull “cores” of soil, thatch and organic material from the ground. This practice has a multitude of benefits to improve turf performance but the main objective is to relieve compaction for improved root development which results in providing an overall healthier turf plant. As the weather moderates in September, it is opportune timing for seed development and a byproduct of core aeration is that it creates additional surface area for seed to attach, germinate and establish. Core aeration paired with overseeding is a perfect combination for any lawn this time of year so please contact us for a consultation!

It’s That Time of Year…

Maplewood MN Tree Service

August 12, 2019 – Well, unfortunately, it is that of time year where a major disease really starts showing up in our urban forests. This disease is responsible for countless oak tree failures every year and continues to show up every summer. The oak (Quercus) genera has two groups, red and white where the red oak group typically have pointed lobes on the leaves and where the white oak group have rounded lobes on their leaves. Oak Wilt will affect all oak species, but is most prominent in the red oak group because the vascular system has a larger porosity than the white group, which is why the disease can cause tree failure in a matter of weeks. Conversely, it can take multiple seasons for white oak group trees to decline and fail. Oak Wilt is caused by a fungal pathogen and spreads by way of insect vector and also underground to nearby root grafted trees. Infected red oaks produce a spore “mat” which attract the beetles due to a fruity aroma. When the beetles traverse through the spore mats, spores cling to their bodies and as the beetles visit other trees, spores attach to those trees and proliferate to cause infection. The beetles are attracted to fresh wounds from broken limbs or pruning cuts. That is why we ONLY prune oak trees in the dormant season as the beetles are not active. It is crucial to identify a wilt situation early, which is usually drooping leaves/petioles and progressive browning of the leaves. Management strategies need to be employed immediately to help reduce exposure to nearby trees. In the above photo, the oak on the right has a significant wilt infection which occurred in a matter of weeks. I have already incorporated countermeasures to protect nearby trees. Please contact us to help if you suspect Oak Wilt at your home or property.

What About Bob?

Circle Pines MN Tree Care

July 31, 2019 – As much as I would like to talk about the comedic classic comedy movie, “What About Bob?” with Richard Dreyfus and Bill Murray, unfortunately, I have to push the pause button and talk about a destructive disease that occurs on our native bur oaks called “Bur Oak Blight” or commonly referred to as “BOB”. This affliction originated here in the Mid-West in the 1990’s and is slowly becoming a substantial issue with our bur oaks and, in some rare occurrences, swamp white oaks. BOB is caused by a fungal pathogen and signs include necrotic/dead tissue on leaves, which leads to premature defoliation. This loss of photosynthesis potential slowly deprives the tree of much needed energy in order to sustain itself year to year. If left to its own devices, BOB can slowly degrade the health of the tree where secondary pests such as the two-lined chestnut borer can and will invade the tree and further the decline leading to failure. Although this takes time, it is crucial to address BOB through disease management with technical materials and also supplementing lost nutrients with a fall season fertilization. If you think BOB is visiting oak trees at your home, please contact your area ISA Certified Arborist here at SavATree to arrange a consultation. The earlier it is addressed, the better for your trees and the overall integrity of your property!

Where Are Your Roots?

July 29, 2019 – Girdling roots can be an issue with any tree species. However, some of the most common are linden (basswood) and maple trees. The condition usually develops early in t  he plant’s life, but girdling roots can be a concern throughout the entire lifespan of a tree. This issue typically starts at the nursery where soil or other organic materials accumulate against the base of the trees. As the years pass with that material on the trunk, adventitious roots develop and encircle the main stem. When a tree is installed at your home, it is imperative to gently remove the piled up soil in order to expose the main root flare. If that soil remains, the condition worsens and the tree’s conductive tissues become restricted as both the tree and root(s) grow into one another. In many cases, our SavATree team can intervene by performing Root Collar Excavation via Air-Spade and follow up with providing supplemental treatments and soil amendments to improve root development and provide a healthier tree long-term. The first photo shows a visual of canopy decline due to girdling roots and, at that point, the tree cannot be salvaged. The second photo shows a tree that a storm simply blew over! Please contact our team if you believe your tree is at risk and have one of our certified arborists consult with you to see what options you may have!

Lawn Update

north oaks mn lawn care

July 28, 2019 – A turf insect that can wreak havoc has been identified in the Minneapolis-St. Paul area. It was once thought that Chinch bugs were not a problem this far north, but now these destructive insects are starting to make an appearance. The customer mentioned their lawn has had many issues in years prior to our team beginning services this year and now we know why. Chinch bugs can be quite the challenge to manage and lawns with a history of Chinch bug issues need to be closely monitored so management strategies can be developed. Please contact us if your lawn looks to have “dry looking” areas but no improvement when watered and also those areas are progressively spreading. These insects are tough to manage effectively but we are up to the challenge! Contact us today for free lawn consultation!
