Just wanted to let you know the trees look amazing. Each of the crew took the utmost care with all the plants as they worked, and they left my yard in better shape than when they arrived. Yay! I appreciate the excellent job! ” - Pam F.

Tree Fertilization

Like all living creatures, trees need certain elements to survive. However, unlike humans, they can’t go very far to obtain what they need. The leaves in the canopy, along with the root system, only convert into food those elements that are within their reach.

Human practices within the urban forest can destroy the natural processes by which plants survive, resulting in soil that is deficient in the minerals and nutrients trees need to convert into food. The pavements of our streets, sidewalks and driveways diminish the available oxygen, organic nutrients and water absorbed by a tree’s roots. The raking of lawns removes potential nutrients that would eventually work their way into the soil. If you have a well-kept yard, neatly mowed and manicured, you probably have hungry trees. And since they can’t order out, you have to do it for them.

Preservation Tree Services can assist you in providing what is lacking in your soil’s composition for the promotion of healthy tree growth. For us, this determination is not a matter of guessing. If necessary, we will take soil samples and have them analyzed to help us make the correct formulations.

We must also take into consideration the current condition of the trees. Some trees are literally starving to death. For immediate nourishment, these trees may need an infusion of essential nutrients and minerals delivered directly into their trunks, similar to an IV drip. Our usual method is called deep root zone feeding through use of high-pressure injections of an organically-based, slow-release fertilizer which we inject below the soil surface. This provides a gradual, long-term source of nourishment for your trees. This application works best for the tree’s needs when applied in the fall, when the tree is approaching dormancy. The vital life juices of trees have all winter to mingle with the nutrients we pump into the soil. In the spring, you should see a robust response as the tree produces its new growth.

Applying a four to six inch layer of shredded mulch around the base of the tree is an excellent means of providing nutrients, oxygen and water to the root zone. This practice also helps reduce the number of unwanted plants competing for the same food sources. This mulch layer is most effective when spread from the root flare of the trunk out to one third the distance covered by the canopy of the tree.
