Environmentally friendly tree and shrub care programs to fit your needs

General Tree has been using environmentally friendly methods as part of our tree and shrub care programs long before they became so popular. From the beginning, we have been committed to using the most environmentally responsible products available and registered by the EPA (Environmental Protection Agency).

Our programs incorporate organic or bio-rational products such as summer spray oil, BT and Pyrethrums as a major source of insect control in our Plant Health Care programs. When we are charged with the health of your outdoor environment, we take it very seriously.

Did you know more than 90% of all insect and disease problems in plants are caused by the plants basic needs not being met?Plant health care services

That’s right. If you meet the basic needs of your plants so they are strong and healthy, their own defense system wards off the majority of pests they encounter along with increasing their ability to fight off diseases. This means you greatly reduce the need for pest control.

The old saying “an ounce of prevention is worth a pound of cure” is really true when it comes to your plants. So, the question you should be asking is “How can I maintain healthy strong plants in my landscaping?”

The answer is Plant Health Care Services by General Tree.

Careful inspection by experts

Plant health care inspections

We inspect your landscape before we treat your plants.

Our technicians are trained to recognize insect, disease and cultural problems and will treat affected plants only when needed.

This results in a healthier landscape and benefits our environment by limiting the amount of chemical control materials applied.

I have greatly appreciated the concern and proactive service that General Tree has demonstrated.
They certainly are as motivated to care for my grounds as I am.

Ornamental Bed Weed Control

This program controls weeds year-round in your ornamental beds, bark dust and gravel landscape areas by using pre-emergent and post emergent as needed.

We'll inspect your landscape on a regular schedule and treat any weeds we find.


Fertilization of plants

Plants in urban landscaping don’t receive the benefit of natural fertilization and so, they require additional fertilization to maintain their health and appearance.

Our nutrient blend replaces and supplements the elements used by plants.

Pressure injected, deep root fertilization aerates the soils while placing water and nutrients right at the roots for optimum uptake by the plants. For certain shallow rooted plants, a liquid application may also be applied.

Free Service Calls

Service calls are free to customers who subscribe to complete programs. We encourage our customers to call if they have questions or need advice about their landscape.
