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.
