Getting a Landscaped Yard to Simulate a Forest Floor
The Root of the Issue
If you’ve ever taken a walk in the woods, and we’re assuming you have if you’re reading the Tree Adviser, you know there is something very different happening under your feet. The forest floor is layered and alive. Fallen leaves, deadwood, mosses, and other organic materials are constantly breaking down and returning nutrients to the soil.
Compared to a forest floor, most DC‑area landscapes, with their sidewalks, roads, patios, and tidy yards, simply don’t leave much room for the slow, quiet work of soil building. Roots end up growing under roads, driveways, and homes with limited access to air, water, and essential nutrients. Lawns are kept clean, leaves are hauled away, and over decades of development, the soil is pressed tighter and tighter, losing the structure trees depend on.
The question becomes, how do I help my trees thrive without the natural advantages of an unmanaged woodland?
Soil-focused tree care has always been central to how we approach tree health. Bio stimulants, soil aeration, and soil decompaction are science based techniques that help restore what development removes. By improving microbial activity, oxygen, water movement, and nutrient access, we create a healthier soil environment that supports stronger roots and more resilient canopies. Trees handle drought, disease, and severe weather far better when the soil works with them.
In short: trees are resilient, but they work overtime in urbanized areas. We can’t recreate the forest floor, but we can absolutely give them a helping hand.
The Return of the Spotted Lanternfly
Pest Update
Earlier this month, one of our Plant Health Care technicians sent a message to the back office that simply said “They’re back”. We knew exactly what he meant.
He was on a longstanding client’s property inspecting her river birch when he spotted a first instar spotted lanternfly. Within minutes the hatch had begun. These tiny black nymphs move quickly and will eventually become the mature, spotted adults we start seeing by late July or early August.
A single egg mass can hold thirty five to fifty individuals, so an early sighting is rarely an isolated one. This is the time of year when vigilance matters, especially for maples, river birches, japanese snowbells and other preferred host trees.
When to call us: Reach out if you notice small black nymphs with white spots on your trees. Early instars move quickly and often appear in clusters, so even a single sighting is worth checking. If you see egg masses, unusual feeding activity, or sudden movement on new growth, our Plant Health Care team can confirm what you are seeing and recommend the right next steps.
Beech Leaf Disease
Important Notice
Beech owners this one matters.
We sent out the alarm last spring when we saw the first signs, but BLD wasn’t nearly as widespread as it is today. This year, symptoms are showing up earlier and on more properties, so it’s worth keeping an eye out.
What to look for:
Dark, thickened bands between the veins, crinkled or curled leaves, reduced leaf size, or a canopy that suddenly looks thin on new growth.
Why this is critical:
BLD is caused by a microscopic nematode that damages beech leaves. Leaves are a tree’s solar panels and when a tree loses energy year after year, decline can happen fast.
In severe cases, Beech trees can die in as little as five to six years. It’s heartbreaking, especially considering the mature Beeches in our region can live well over a century.
Treatment options:
While there’s no 100% cure, proactive care can make a big difference. Proper watering, avoiding soil compaction, and targeted nematicide injections can help protect trees from the nematode and slow disease progression.
