Better Treatment for Apple Scab

We are certain that all of our customers are loving their treated Crab Apple, Hawthorne and Maple trees this year!

A clients Crab Apple treated by Tree Green. Photographed 8/17/17.
Notice the thick, full canopy and the shade and privacy the tree provides.

Apple Scab Fungus is horrendous again this year as is evidenced by this second photo. If Apple Scab is really bad then so is Quince Rust on Hawthornes and Tar Spot Fungus on Maples.

This photo was also taken on 8/17/17 and is on the same street as the Crab in the 1st photo.

As you drive around, compare your treated, crab apple’s appearance to others in your neighborhood. You will notice a similar, amazing difference!

How did we come up with an effective treatment? What happened was this…

Two years ago, in 2015, we received 8 or 9 calls from clients saying their Crab Apple seemed to be suffering from Apple Scab despite us having treated their tree that season. Upon inspection, we did see some of the fungus present and although their Crab didn’t look nearly as bad as their neighbors un-treated Crab, they weren’t the results they, or we, were used to getting. Since we had only received 8 or 9 calls out of over 1,200 Crab Apple clients we thought that maybe it was a fluke and some other environmental issues were at play so we didn’t make too much of it.

But then 2016 came along and with it so did over 40 calls and emails from clients with the same observation; their Crabs seemed to have Apple Scab despite having received treatment. We figured if 40 clients called, there could have possibly been another 100 or so who noticed the same thing but chose not to call, attributing the lack of results as we did the year prior, to be a fluke.

We went back and looked at the trees of the 8 or 9 clients who had initially called in 2015. Those trees were in even worse shape in 2016 than they were the year prior so we knew there was a serious issue to deal with. We knew this trend would accelerate  rapidly in the next few years.

We determined that the fungal spores were developing a ‘resistance’ to the high-end fungicidal products that we have used for over 20 years so we had to make a change. Fungicides come in 9 different classifications. This year we decided to make a wholesale change and switched to entirely different, and more expensive, classifications of fungicides to get better results this season. Going forward we will rotate products year to year to prevent the possibility of another resistance issue.

Tree care is a highly complex field. It’s not much different than your doctor making a change in personal medications when they find that an earlier medication is not working to its expected potential. We’ve all heard about antibiotics no longer controlling certain infections.

So what did we do?

This year we acidified the spray tank water to lower the water’s pH to a level that helps products work at their peak. Then we mixed three (3) different classifications of fungicidal products together and added a surfactant that helps the product better absorb into the leaf and repel rain after it has been applied. We know of no other company who goes to the lengths that we do to get the best possible results.

If we treated your Crab Apple this season, we hope that you really enjoy your healthy Crab Apple tree(s). Sorry in advance for all the extra leaves you will have to rake this Fall!  Enjoy the rest of your Summer.

 

 

 

Beware of Lawn Care Company Scare Tactics

Once again, we are hearing from clients who state that their nationwide lawn care companies, whom will remain nameless, have left information that their property is under major attack from multitudes of insect and fungal issues. This scare tactic has been going on for years and most of you may have already experienced it.

To generate new sales, major national lawn care companies pay ‘bonuses’ to their lawn care employees who take the time to leave a supposed ‘property evaluation’ detailing all kinds of insect and fungal infestations supposedly spotted on their client’s trees and shrubs. Whether these employees know the names of certain insects and funguses given to them by these companies or not, what we find repeatedly is that what these companies say they see on your trees has nothing to do with these mentioned insects or funguses.

Many natural, environmentally related circumstances cause unavoidable leaf issues. Almost every residential property has trees or shrubs with Winter Burn or Summer Leaf Scorch, which is attributed to some unseen insect or fungus by companies who operate this way.

If you have received a notification like this, and wish to pursue it, we ask that you set up an appointment for their representative to meet you at your property. Tell them that a Tree Green representative will also be there to meet both of you, on a day and time of their choosing. We will discuss these purported issues and then you can decide what you want to do from there. We guarantee you that they will have some reason to avoid this.

The point is, if their lawn care people really knew and understood complex tree and shrub issues, they themselves would be treating trees and shrubs for those companies, not treating lawns. We don’t want to come off as bashing the competition, as we know that is not a good business practice.  But these tactics cause us so much aggravation, and so much wasted time answering questions from nervous clients, that we feel the need to call these companies out on this deceptive practice.

Iron Chlorosis of River Birch and Oak

Is your River Birch or Oak, specifically Pin Oak, displaying lime green or even worse, yellow leaves throughout the entire tree? If it is, your tree is trying to tell you something very important: it is in the process of dying.

River Birch and Oaks do not do well in many local neighborhoods. If your neighborhood has a lot of clay in the soil, the PH of the soil is such that it prevents the trees roots from naturally absorbing Iron from the soil. Since River Birch and Oaks need iron more than any other mineral, it is necessary that iron be injected in to the tree to green up the leaves or it will die.

Please view the below two photos.

This sick, Iron deficient River Birch would have died in 3-4 years without treatment. We treated it on treated 6/6/17.

This is the same River Birch following treatment by Tree Green taken 7/17/17 – just 6 weeks later!

 

 

 

Leaves act like little solar panels to absorb sunlight and then turn it into the starches and sugars a tree requires for energy. The ‘green’ inside the leaf is chlorophyll, which plays a crucial role in this process. When trees that are supposed to have green leaves have lime green or yellow leaves instead, the tree is much less efficient at absorbing sunlight and converting it into the energy it needs to survive. Eventually, this process will stop altogether. Simply put, without that energy, the tree will die.

In our 47 years, we’ve learned that amending the soil by adding Iron does not work. Again, it is not the lack of the Iron in the soil that causes the chlorosis, but rather the pH of the soil preventing the tree from absorbing it. Therefore, no amount of Iron in the soil will green up these trees. Our experience has shown that systemic injections directly into the trunk with chelated Iron extends the tree’s life for the longest period of time. It is important to note that even with treatment, eventually, 12, 18 or 24 years from now, the tree will still ultimately die from this condition. Unfortunately, we just can’t fool the tree forever by bypassing the roots. Eventually the tree will no longer accept the Iron.

If you have a River Birch or Oak exhibiting symptoms of this deficiency, please give us a call or send us an email to come out and inspect it so we can share a game plan for treatment with you. Once treated, your tree will be much greener and much healthier just weeks later.

Understanding our process and what to expect.
We typically treat these trees once every three (3) years for this condition. However, if your tree is exceptionally yellow, we will recommend two successive years of treatment before we go to the once every three year program. The year the tree is treated, it will green up as shown in the photo above. Then in the second year, a non-treatment year, it will start to show signs of yellowing but will still be greener than it was the previous year prior to the injection. In the third year, another non-treatment year, it will be fairly yellow again. Then the following year, the beginning of the 4th season, we re-inject the tree to green it up again so it can rebuild energy for 3 more years.

We have found that as long as the tree can build energy for the year or year and a half that its leaves are greener, it will have enough energy to sustain it for the three seasons between treatments.

You may be asking yourself, why not just inject these trees ‘every’ year. Cost is one reason. Why inject the tree any more frequently than is necessary? The second reason is that it is a rather invasive process. Treatment requires us drilling a series of half inch diameter holes into the trunk all the way around the tree and inserting plugs or implants containing the Iron, bypassing the roots. They dissolve under the bark and move up the tree with the sap flow. While it is generally agreed upon amongst Arborists, including ourselves, that drilling holes into a tree trunk isn’t a great idea, we still opt to use this process since we know the alternative is a dead tree. It is important to note that Tree Green has never lost a tree from the implanting process itself, only from the Iron deficiency if left untreated.

Please give us a call to have us check our tree  for iron deficiency, and for treatment.
