To maintain healthy apple trees, regularly inspect leaves for signs of yellowing. Implement appropriate treatments based on the identified cause. Adjust care practices to ensure optimal growing conditions.
My interest in trees started when I first saw the giant sequoias in Yosemite.
I was a teenager then, and I remember thinking, “I need to learn more about this.”
That moment stuck with me.
A few years later, I went on to study forestry at Michigan Tech.
Since graduating, I’ve worked in a mix of hands-on tree care and community education.
I’ve spent over ten years helping people understand how to plant, maintain, and protect the trees in their neighborhoods.
I don’t see trees as just part of the landscape.
They are living things that make a real difference in our daily lives.
