Our Approach

Comprehensive Plant Care Programs

Protection

Insect & Disease Control

Targeted treatments for common Long Island pests including scale, aphids, spotted lanternfly, and fungal diseases. Applied at the optimal time in each pest's life cycle for maximum effectiveness.

Nutrition

Fertilization & Soil Care

Deep root fertilization delivers essential nutrients directly to the root zone. Soil testing identifies deficiencies and pH imbalances that limit plant health and vigor.

Prevention

Preventive Programs

Annual PHC plans include scheduled monitoring visits, dormant oil applications, and preventive treatments timed to Long Island's pest emergence windows — stopping problems before they start.

Common Questions

Plant Health Care FAQ

What is plant health care (PHC)?

Plant Health Care is a proactive, science-based approach to maintaining the health of trees, shrubs, and ornamental plants. Rather than reacting to problems after they occur, PHC programs monitor plant health throughout the season and apply targeted treatments to prevent disease, insect damage, and nutrient deficiencies.

What pests and diseases are common on Long Island?

Long Island landscapes commonly face issues including spotted lanternfly, emerald ash borer, scale insects, Japanese beetle, apple scab, fire blight, and various fungal diseases. Our licensed horticulturists identify and treat these issues before they cause lasting damage.

How often are plant health care treatments applied?

Treatment frequency depends on the specific program and plant types. Most properties benefit from 4–6 visits per year, timed to coincide with pest emergence cycles and disease pressure windows.

Do you offer organic plant health care options?

Yes. We offer integrated pest management (IPM) programs that minimize chemical use by combining cultural practices, biological controls, and targeted low-impact treatments.
