Soil Injection Fertilization
Fertilization is an important aspect of tree care in modern landscape settings. Trees require certain nutrients to function and grow. Most residential soils are stripped of natural organic nutrients due to soil disturbance during construction and yearly leaf removal. Therefore these soils do not contain sufficient available nutrients for sustained health of trees, and supplemental fertilization is quite beneficial.
Process - Our fertilization process uses hydraulic pressure to inject liquid solution to 6"-8" below the soil to where trees feeder roots are located. This also places the fertilizer underneath the roots of any competing plants such as grass or other ground cover.
Soil Aeration Benefit - By the process used the soil beneath the canopy of the tree is loosened and aerated. This allows better soil penetration of water and air, and allows easier root growth/elongation due to a looser soil.
Fertilizer Solution - Our fertilizer blend is formulated specifically for trees. It consists of a long-lasting, low chloride, 5-10-10 (N-P-K) fertilizer with slow release organic compounds that contain micronutrients and beneficial mycorrhizae fungi.
N (Nitrogen) - Nitrogen affects the vegetative growth on trees, it is used in producing new shoots, buds, and leaves. Nitrogen is also the main component of chlorophyll which is the green chemical in leaves responsible for photosynthesis which is how a tree produces its energy.
P (Phosphorus) - Phosphorus is very important for root health and development. It is used more heavily during bloom and seed production. It is generally released into soil from decomposing organic matter.
K (Potassium) - Potassium also aids in root development and the formation of chlorophyll as well as other important plant compounds. It also helps with disease resistance and absorption of trace elements.
Mycorrhizae - Mycorrhizae are a beneficial fungus that attatch to roots and form a symbiotic relationship that provides an extension to the trees root system. Mycorrhizal fungi can increase the absorbing surface area of roots from 100-1000 times. They also release enzymes that help dissolve more tightly bound micronutrients. Re-establishing mycorrhizal populations can dramatically improve plant performance by increasing water and nutrient assimilation.
Micronutrients - Micronutrients are essential for plant growth, but are only needed in small amounts. The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo), and zinc (Zn).
Timing - When should your trees be fertilized?
Spring - Most trees flower and have a flush of growth in the spring followed by slower growth in the summer and fall. It is beneficial to have nutrients available to the tree for this growth period. Fertilizer should be applied from when the ground thaws until the trees start growing in late early May.
Fall/Winter - Once growth stops in the fall, until the ground is frozen is very beneficial for fertilization. At these times the treeâ€™s roots take the nutrients from the soil and apply them to important health-promoting functions such as root development and disease resistance, rather than simply putting out new growth.
Nutrient Deficiencies - If the trees leaves are discolored or abnormal there is a chance of macro or micro nutrient deficiency and fertilization may help to alleviate the issue. Have our arborist come check your trees if they appear sick so recommendations can be made.
