Fertilization of Larger Trees
When discussing fertilization, what comes to mind is often the idea of providing nutrients to fruit-bearing plants, flowers, and grasses. Large tree fertilization, however, is an important part in making sure your larger trees are healthy and continue to stay that way, even if they are already well-established or have been planted for a long period of time.
To determine how well a large tree is growing, you can measure the distance between the ring from the budding on new twigs, and the tip of the twig, whether it has greened or not. This gives you a general idea of how long, in inches, the tree has grown in any given direction. Larger varieties of trees, once matured and mostly grown, will only continue growing roughly half a foot to a foot in new length each year, even without the addition of fertilizer.
Fertilizers for trees can be chosen based on the soil type and tree type. Inorganic fertilizers, in powder or bead form, contain nitrates that help trees stay healthy and strong. Natural fertilizers consist of organic materials, ranging from animal dung to mulched leaves and bark. These compounds break down over time and become absorbed and utilized by the tree, allowing the tree to grow much faster, whether it is still in its early stages or well-established and matured for the most past.
