Arbor Masters

There is not one standard plan for fertilizing trees and shrubs. Our arborists base the fertilizing program on the type of plant/tree, the time of year, and the existing nutrient ratio and composition of the soil. While the trees and shrubs extract some nutrients from the fertilizer spread on the lawn, generally there are not enough nutrients in the soil to produce the growth needed or withstand other summer-related stresses.)

In many ways, fertilizing your trees is kind of like you and me taking our vitamins. We are supplementing our regular diet with nutrients that will help us remain healthy. In the urban landscape, deciduous shade and ornamental trees benefit from yearly fertilization such as: more rapid growth; faster recovery from injury, pruning or pest problems; overall improved health and better foliage color. While established trees benefit from fertilization, a newly planted tree does not, until the root system has at least partially reestablished itself. So, fertilizer is not recommended during the first year or two after planting. The exception is the addition of a low analysis starter fertilizer at the time of planting, which can help reduce transplant shock. (Dennis Patton, Johnson County (Kansas) Extension Agent.
