Old trees are like old men and in our beautiful, historic Jacksonville neighborhoods, April and May aren’t just beautiful months, they’re critical months for “old man” tree health. Many of our neighborhood trees are more than 120 years old and just like men do when they age, trees need extra nutrients and inoculations to live to an even riper old age.
As oaks, magnolias, maples and other canopy trees push new growth, they’re also becoming more vulnerable to insects, fungal pathogens and environmental stress. Right now is the ideal window for proactive care using trunk injection systems like Tree-age (pronounced “triage”).
Tree-age is a systemic insecticide delivered directly into a tree’s vascular system through small, sealed injection ports at the base of the trunk. Unlike traditional sprays that can drift or wash away, trunk injections move internally with the tree’s natural transport system, distributing protection throughout the canopy. When applied correctly, this method targets destructive pests while minimizing exposure to pollinators, pets and surrounding landscapes.
Why spring? In April and May, trees are actively transpiring (drawing water and nutrients upward). This movement allows injected treatments to distribute efficiently before peak insect pressure arrives in early summer. In our region, common threats include borers, aphids, scale insects and certain caterpillar species. Left untreated, these pests can weaken trees, reduce canopy density and make them more susceptible to storm damage.
Trunk injection isn’t a cure-all. It works best as part of a broader tree health plan that includes:
- A professional inspection to identify species-specific risks
- Proper pruning to remove deadwood and improve airflow
- Mulching (2–3 inches deep, kept away from the trunk flare)
- Irrigation during prolonged dry periods
- Soil testing when nutrient deficiencies are suspected
Homeowners considering trunk injection should ask any tree service a few important questions:
- Does the company have extensive experience injecting pesticides and nutrients into tree vascular systems?
- What pest or condition is being targeted?
- How long will the treatment remain effective?
- What are the environmental considerations?
Large, mature, “old man” trees add significant value to our homes and neighborhoods. Protecting them isn’t just about aesthetics. It’s about preserving shade, property value and the character of our community. April and May provide a narrow but powerful window to strengthen these living assets before summer stress sets in.
Healthy trees don’t happen by accident. They happen by informed, timely care…and now’s the time.
