Fall Tree Fertilization: Protecting Roots Before Winter
Why Fall Fertilization Matters
As leaves begin to change and temperatures cool, many homeowners assume their trees no longer need care. But the opposite is true—fall is one of the most important times of year to support your landscape. At Superior Arbor Care, we use this transitional season to reinforce tree health below the surface, focusing on what matters most: the roots.
Preparing Roots for Dormancy
Trees in Fairfield County begin slowing their top growth in autumn, but their roots remain active well into the early winter. Fertilizing in fall provides a slow-release dose of nutrients that support root regeneration, cellular repair, and energy storage, all of which are crucial for surviving the winter and thriving next spring.
Stronger Starts in Spring
Trees that receive fall fertilization emerge from winter healthier, with more vigor and resilience come spring. This is especially important for younger or newly transplanted trees that need to establish strong root systems, as well as mature trees that may have experienced summer drought, pest pressure, or heat stress.
Evergreens Need Fall Support Too
Broadleaf evergreens and conifers continue to photosynthesize even in winter, meaning they rely on stored nutrients to stay green and resilient. Fertilizing in fall helps evergreens maintain their color, avoid winter burn, and defend against early spring pests and diseases.
Mulch as an Insulating Ally
After fertilization, we often recommend applying a layer of organic mulch—like shredded bark or leaf mulch—around the root zone. This provides critical insulation from sudden temperature drops, helps retain soil moisture, and prevents compaction from snow and ice. Just be sure to keep mulch a few inches away from the trunk to avoid trapping moisture against the bark.
Fertilization as a Line of Defense
Healthy, well-fed trees are better equipped to resist borers, scale insects, and fungal diseases that often take hold when trees are weakened. By combining fall fertilization with strategic insect control and pruning, we reduce the chances of infestation or damage during the vulnerable winter months.

Our certified arborists tailor each fertilization treatment to the species, soil conditions, and goals of your property.
