"Our Goal is to always leave your property better than when we started".

Chances are your trees have a deficit of Chlorosis.

Iron chlorosis is a term describing leaf yellowing (lack of chlorophyll) due to insufficient iron. Iron is a mineral essential for plants to make chlorophyll, in turn needed for photosynthesis. Lack of iron in a tree may be due to a high iron need, less effective iron uptake, or insufficient usable iron in the soil. Colorado soils generally have adequate to high iron levels, as evidenced by the many red soils and rock formations. However, Colorado soils are mostly alkaline, causing most of the iron to be in an insoluble form not usable by plants. Symptoms of Iron Chlorosis include the newest leaves towards ends of brands are generally the ones that are yellow, veins of affected leaves remain green & in some advanced cases, leaf edges become scorched and leaf interiors show dead brown areas as cells die.
