Field Intelligence

AI that knows the property, not just the species.

Describe what you see. The AI connects the dots — species interactions, regional disease patterns, seasonal timing — backed by ISA standards, USDA data, and university extension research.

Field Intelligence 742 Maple Heights Dr
Three ornamental crabapples along the fence line, orange spotting on leaves. Also have an old eastern red cedar in the back corner.
That combination is a red flag. Malus spp. near Juniperus virginiana is the classic host pair for cedar-apple rust — Gymnosporangium juniperi-virginianae. The fungus needs both species to complete its life cycle. Orange lesions on the crabapple leaves confirm active transfer.

Per OSU Extension, the spore release window in central Ohio is April through mid-June when rainfall exceeds 0.5" and temps are above 50°F. You're in it right now.

Recommendation: Fungicide on the crabapples is reactive — it slows spread but won't eliminate the cycle while the cedar remains within spore range (~1 mile, but proximity worsens severity). Long-term option is replacing the cedar with a non-host conifer or selecting rust-resistant crabapple cultivars on the next planting.

Want me to pull the resistant cultivar list for Zone 6a?
Yeah, and what would you estimate for hours on the cedar removal?
Depends on the size and access — you're the one looking at it. A mature J. virginiana in a back corner with fence-line constraints, I'd estimate 3–4 hours for a solo climber with rigging. But the boots-in-the-dirt number is yours.

About the builder

Arlington Tree Co. →

ArbAssist is built by David All — an arborist, researcher, and builder who's spent 20 years solving problems nobody handed him a manual for. He co-authored a peer-reviewed study on opioid treatment deserts with Ohio State University (PLOS ONE, 2021), wrote speeches read on the U.S. Senate floor, led outdoor education programs for kids at a Pennsylvania nature center, and ran a $4.6M agency where attention to detail was the product.

Now he cares for trees in Upper Arlington, Ohio with hand tools and old methods, studies for his ISA Certified Arborist exam, and builds the tool he wished existed in the field. ArbAssist comes from the same place all his work does — show up, pay attention, document everything.
