Tree care consulting, natural organic tree and lawn care services, professional witness for courtcases, soil management, tree preservation, and soil rehabiltation after chemical pesticide applications.

What is your definition of Integrated Pest Management (IPM)?

IPM has no meaning. IPM needs to be redefined in court.

Is pest management performed on a specific schedule?

Most tree problems are trouble in the rhizosphere. Insects and fungi are indicators of other problems.

How are pest problems identified?

Pests are not a problem, they are signs of other problems. We do not treat signs, we treat the system.

What practices do you use to prevent and/or control pests?

Our goal is not controling insects and/or fungi. Our goal is far more intense than that. It is based on true biology.

Do you use biological controls?

In a sense we do, by proper mulching.

Do you use borates?

Boric acid.

Do you use synthetic chemicals?


What are the top 10 pesticides you use/sell/recommend?

We do not recommend any. When we do, its Ivory dishsoap, tobacco juice or coffee grounds.

If pesticides are used, how much are used per year of each?

No pesticides.

Does your company perform habitat modification?

Yes. Eco-art nurselogs and soil management. We also do encourage bat houses, and bird houses since these animals feed on


Do you use any physical or mechanical controls?


What type of fertilizers do you use/sell/recommend?

Sustain - Natural organic fertilizer, plant health care products, roots, composted tree trimmings, composted leaver, nurse logs, certified organic spent mushroom soil (Mother Earth Organic Mushrooms).


What do you usually use/sell/recommend for addressing:

termites Remove chemically altered wood.

cockroaches Boric acid and talc.

fleas Vaccum cleaner.

carpenter ants Carpenter ants help trees by controlling the moisture content by making galleries. This helps stall the decay pathogen and thus helps the tree.

fire ants They attack the formosa termite.

ants (indoor) DNR

crabgrass Talk therapy.

dandelions Talk therapy.

How do you evaluate effectiveness of your pest management

We do not have a pest management program. We have soil management systems. We have a systematic approach to the care of trees and lawns. We do landscape enhancement.
