Fall Tree Fertilization

Fall is the most crucial period for trees to rejuvenate roots and prepare for the coldest time of the year. With the onset of winter, trees start fabricating a strong network of roots to adapt to the extremities of weather. Fall tree fertilization stimulates root development allowing them to emerge with renewed vitality in the spring.


Most people believe that only turfs and shrubs require fertilization, while trees can generally afford to go unnoticed. However, tree roots need to be conditioned with fertilizers containing phosphorus and potassium in order to initiate the hardening off of foliar tissues. When high levels of soluble nitrogen are introduced through fertilizers, foliar tissue aging is delayed pushing back the tree’s preparation during the fall. When you seek assistance from tree care professionals and ask them to communicate to you the mechanism of fall fertilization, you will find that nitrogen used during this specific season is usually “low or slow.”


Like their contemporaries in the garden, trees must be furnished with regular care and nourishment to counteract dust, pollution and other environmental stressors. Over time, trees lose their nutrients and become weak at the base calling for immediate measures that will give them a long life. Apart from this, here are a few other advantages of fall fertilization.

  • For a tree to prosper, the strength of its roots matters the most. For the leaves and branches to take the form of a lush green canopy, they must be supplied with valuable nutrients and fertilizers evenly distributed in the surrounding soil.
  • Trees require periodic replacement of nutrients and the most suitable way to do this is through fall fertilization. Deep root tree fertilization replenishes the soil and catalyzes tree growth and development for the coming year.
  • Fall brings a breathtaking landscape of leaves changing colors, but this seasonal aging process actually depletes trees of nutrients. Fall fertilizers will not only help trees renew their color for the winter but also form a mesmerizing appeal when they green up in the spring.
  • Lastly, fall fertilization assures a long and healthy life for your trees. When fertilized properly, trees attain their potential heights and sizes and gain protection from insects and infections formed around the roots from moisture.


In the fall, most trees start eliminating their foliage for the rest of the year, thereby decreasing their rate of growth; consequently, the roots start borrowing available nutrients from the soil. When trees are fertilized, the extra nutrients are stored by the roots and utilized for the next season. Fall fertilization should be practiced annually to benefit the health of the tree.
