Tree and Plant Fertilization

Tree and Shrub Fertiliization Services by Elk Creek Lawn & Tree CareTrees require certain elements, known as macronutrients, in relatively large quantities for it to function and grow properly, with the most important element being Nitrogen. Fertilizing a tree with Nitrogen will help to increase growth, reduce the susceptibility to certain pests and disease, and may help to reduce declining health in plants depending on the circumstance. Naturally occurring soil nitrogen comes from organic matter and the atmosphere and it is critical to photosynthesis and other plant processes. It can be limited in an urban setting where leaves and other organic material are routinely removed from the lawn causing a need for plant fertilization. While nitrogen is the key, a complete fertilizer will also contain Phosphorous and Potassium, although for trees, a complete fertilizer is not usually necessary as nitrogen may be the only limited element. Other elements, known as micronutrients, are required in lower quantities but can also have a profound effect on a plants health. Deficiencies in iron, manganese or zinc may need to be treated with supplemental feedings. For long term release of Nitrogen, plants should be fertilized with a slow release fertilizer. This will also reduce fertilizer leaching while eliminating salt and fertilizer burns to the leaf. While a slow release fertilizer can be applied at any time throughout the year when the ground is not frozen, best results are seen when plants are fertilized soon after bud break and again in the fall before dormancy. Over fertilizing can severely damage or kill trees and plants while no fertilizer will likely promote stressed plants with low growth rates, so why not let Elk Creek Lawn and Tree Care handle your plant health care needs.lawn-care-2b

Tree and shrub fertilizations are injected into the root zone following the drip line. Applied in a slow release formulation, this will provide a timed release of Nitrogen to the roots while promoting health, vigor, even growth and uniform color.

Supplemental Foliar fertilizations may be needed in urban areas with tightly packed root systems or compacted soil. Applied as a topical spray to the leaves or needles, it is then up taken through the plant to provide food to the roots.

Lawn and Shrub Fertilizing in Golden, Denver, Arvada and LakewoodMycorrhiza Injections are performed to promote root growth on new or stressed plants. Beneficial fungi strains are tank mixed with Revive and Humic Acid to alleviate micronutrient deficiencies. Mycorrhiza is the symbiotic relationship formed between the plants roots and these fungi. The fungi colonize the roots system of the plant providing increased nutrient and water absorption while the plant provides the fungi with sugars produced by photosynthesis. Once this relationship is formed, a plants health will most likely improve or will not diminish.

Iron deficiencies are treated by injecting into the root flare of the stressed tree using a chelated iron source. This counteracts a tree not absorbing sufficient amounts of Iron or when it is unable to use the Iron present.
