Most deciduous hardwood trees, such as oaks and elms, benefit from annual fertilization—but not all trees require the same nutrients. Fertilization needs vary based on species, age, and overall health.

In a natural forest, trees self-fertilize as fallen leaves decompose, replenishing the soil with essential nutrients. However, in urban and residential landscapes, we often remove leaves and introduce grass and shrubs that compete with trees for nutrients. Proper fertilization in these settings helps mimic nature’s process, ensuring trees receive the nutrients they need to thrive.

For best results, consult a certified arborist to determine the right fertilizer mix and schedule for your trees.
