Ever wonder why one tree in your yard is struggling while the rest thrive? 🌳🧪 The answer is could be in the soil.

Urban development heavily alters natural soil systems, but a quick soil test takes away the guesswork. Your Wachtel Tree Science ISA Certified Arborist will sample your soil, present the findings, and create a custom plan to restore long-term soil health.

When to test your soil:

📍 If you've never had a soil test done
📍 If you've moved into a new property
📍 If your trees or shrubs are showing signs of stress
📍 Before planting new trees to help guide plant selection

Contact us today at https://www.healthytrees.com/contact to schedule your soil sampling.

Our Consulting Department recently performed a tree risk assessment on a mature pine at the Aldo Leopold Conservation site. Assessments like this help identify potential hazards, evaluate tree health and structure, and provide recommendations for managing risk, while keeping preservation at the forefront whenever possible.

The landscape surrounding the Leopold Shack and Farm holds a special place in conservation history. The Shack, a rebuilt chicken coop along the Wisconsin River, was once part of the Leopold family’s cherished retreats and is now the heart of the Aldo Leopold Foundation’s programs. Today, thousands of visitors experience this landscape through tours, classes, and events, learning about the ecological and ethical relationships between people and the soil, water, plants, and wildlife.

We’re proud to contribute our expertise to caring for the trees that are part of this living classroom and the legacy of conservation that continues to inspire visitors today. Mature trees are valuable parts of our landscapes and ecosystems. With the right knowledge and care, we can help ensure they remain safe, healthy, and standing for years to come. 🌳

Have you spotted these silky webs on your trees? 🕸️🌳

You may be looking at fall webworms, a common pest that creates solid, silky webs at the ends of tree branches and feeds on leaves from inside the webbing.

🌿 Commonly affected trees include:
• Wild cherry
• Black walnut
• Mulberry
• Crabapple (pictured)

What can you do? Physically remove the webs as you spot them in the fall. Insecticides are typically not necessary.

A little attention now can help keep your trees looking their best! 🍂

A few of our arborists recently attended Connecting Plants and People at Johnson's Nursery 🌳
The event focused on the many benefits of planting native trees and plants, from supporting local wildlife and pollinators to creating healthier, more resilient landscapes. We’re always looking for opportunities to expand our knowledge and bring the best information and recommendations back to our clients.
We’re grateful for opportunities like this to connect with other plant professionals, learn from one another, and continue growing our passion for trees! 🌿
