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.

Winter Burn on Maple Trees

We’ve had a number of clients asking what Winter Burn and/or Anthracnose Fungus that we referenced in our last blog post looks like on Maple Trees. So, we decided to send out a follow-up photo.

anthracnose on maple leavesNotice the browning and puckering of the leaves. In some cases the leaves may actually be even more shriveled and blackened in color.  Most of this type of damage will appear either in the lower quadrants of the tree or on the windward side.

Again, be aware that this type of damage will show up on many different species of trees and shrubs. No need to be overly concerned. Just something Mother Nature decided to dish out this year!
