Tree Health & Disease Treatment in South Jersey
Diagnosis and treatment for sick, infested, or stressed trees.
Pricing: $95 diagnostic visit; treatments $150–$800 depending on size and approach
A sick tree is usually sick for a reason that’s two steps back from what the homeowner sees. The thinning crown is real. The premature leaf drop is real. But the cause is often a girdling root choking the trunk since planting, soil compaction from the kitchen addition four years ago, or a borer that only moved in after the tree was already stressed.
Treating the symptom without the cause is expensive and doesn’t work. The diagnostic visit is where we find the cause.
What we see most in South Jersey
- Spotted lanternfly. Established across Camden, Burlington, and Gloucester since 2019. Hits silver and red maples, willows, river birches, and tree-of-heaven hardest. The state ran a stomp-on-sight campaign for years for a reason.
- Bacterial leaf scorch. Chronic. Pin oaks first, then red oaks, scarlet oaks, and sycamores. Marginal browning that progresses inward each year. Common on mature street trees in Cherry Hill, Voorhees, and Mount Laurel where pin oaks went in by the thousand in the 1960s.
- Bagworms. Small caterpillars in silk bags. Hammer arborvitae, junipers, and Norway spruce. A heavy year kills an evergreen.
- Emerald ash borer. Wiped out most of the white and green ash in our service area. The untreated ashes are gone. The few we keep alive get systemic injection every two years.
- Anthracnose. Fungal. Dogwoods, sycamores, white oaks, maples in a cool wet spring. Looks worse than it is.
- Phytophthora root rot. Soil pathogen. Wet ground. Kills rhododendron, azalea, and dogwood near downspouts and gutter splashes.
- Bronze birch borer. Working through the river birches that 1980s and 90s landscapers planted everywhere. Most are now in decline.
- Two-lined chestnut borer. Opportunist on stressed reds and pin oaks — often follows a drought year.
- Pine bark beetle and pitch canker. Pinelands edge — Medford, Williamstown, Mullica Hill. Drought stress brings it on.
How a diagnostic visit works
- We walk the whole property first. Stress in one tree often points to a yard-wide problem — a broken drainage line, a regrade, road salt, soil compaction around the house.
- We look at the tree. Trunk, root flare, soil, canopy, leaves. We probe for decay where the trunk tells us to. Tissue samples if we need a lab.
- Written report. What’s wrong. What’s reversible. What isn’t. What each option costs. Sometimes the answer is “do nothing — pull the mulch volcano off the root flare and the tree comes back.” Sometimes it’s a removal.
- Treatment plan only if it’s warranted. One to three visits across a season, scheduled around the pest. Soil drench in fall when roots take it up. Foliar in early summer when nymphs are vulnerable.
What it costs
- Diagnostic and written report: $95 (waived if you go ahead with treatment)
- Soil-applied systemic (borers, sucking insects): $150–$400 per tree depending on trunk diameter
- Trunk injection (when soil application isn’t appropriate — near water, paved over): $200–$600
- Foliar pass (fungicide or insecticide): $175–$450 per residential canopy
- Cabling and bracing on structurally weak trees: $300–$1,200 per run
When to call
- Crown that didn’t fill in this spring.
- Fall color in July or August.
- Mushrooms or shelf fungus at the base.
- Sticky honeydew on the leaves, sooty black mold on whatever’s underneath.
- D-shaped exit holes and frass on the trunk — emerald ash borer’s signature.
- Cracks at major branch unions or visible decay cavities.
- Construction within the dripline in the last few years.
What we won’t do
We don’t deep-root fertilize trees that don’t need it. South Jersey soils aren’t nitrogen-poor, and over-fertilizing pushes tender growth that pests find first.
We don’t treat ashes that are already past 50% crown thinning. That’s a removal call.
We don’t cable a tree that’s structurally done. Cables don’t bring rotted wood back.
For trees we can’t save, removal and a replant with the right species for the lot is usually the right answer. For trees we can save, we often pair the diagnostic with corrective pruning the same day.
We treat trees across Medford, Moorestown, Mullica Hill, and everywhere our trucks reach.
