Tree Fertilization and Tree Disease Treatment to Preserve Your Investment

Trees represent a sizeable investment to most homeowners, as well as for many businesses and municipalities; and trees require nutrients to live and thrive. When one or more of these nutrients are deficient in the soil, the tree will not reach its full landscape potential, will be more susceptible to disease and insect problems, and will have a shorter life than a similar, well-fertilized tree.

Tree disease diagnosis and tree protection treatment begins with a comprehensive inspection of your landscape by one of Gregory Forrest Lester’s certified arborists. Our arborists will recommend an effective, economical, and environmentally sound solution to treating your trees. Gregory Forrest Lester’s experience, expertise and state-of-the-art equipment enable us to quickly diagnose tree diseases and recommend specific treatments for tree protection and vitality.

Protect Cincinnati-Area Ash Trees from the Emerald Ash Borer (EAB)

We recommend you begin Emerald Ash Borer (EAB) treatment while ash trees are still relatively healthy. This is because the insecticides used for EAB control act systemically — the insecticide must be transported within the tree; a tree must be healthy enough to carry a systemic insecticide up the trunk and into the branches and canopy. The certified arborists at Gregory Forrest Lester can advise you of your options for protecting your ash trees.
