TRUNK PAINTING for BARK PROTECTION



White latex paint applied annually to tree trunks helps protect against killing of cambium or bark from sudden temperature changes in late fall and winter. Painting the lower trunk makes it easier to detect insect borer infestation, and may deter them. Addition of rabbit repellent to the paint protects young trees from bark stripping by rabbits during the winter.

To make trunk paint, mix one gallon of white interior latex paint into 4 to 5 quarts of water. Do not use oil-based paint. If needed, add rabbit repellent as per the label directions.

Mix these well, and pour the final mix through a nylon stocking to filter out lumps that would clog the sprayer nozzle. Hand-pump backpack sprayers work well for application.

If protection from rabbits is not needed, omit repellent from the mix and spray only the south half of the trunk and lower scaffolds. It is only the lower parts of the tree exposed to warming by sunlight that need protection of the reflective paint. For best weather resistance, latex paint should be applied during mild (50oF or higher) dry weather.
