What Are My Trees Fertilized With?

Flat Plains Services Inc fertilizes trees using a unique formulation and system. Trees are slowly fertilized in the natural forest by decomposing leaf litter. In landscaping, leaf liner is removed, pulling out all natural nutrient recycling and organic matter.


The Doggett Corporation, through independent and university research, has developed slow-release fertilizers. These fertilizers closely mimic what occurs in the natural setting, only with more accuracy and uniformity. These formulations contain slow-release nitrogen (a nutrient that most urban soils lack), which breaks down with soil microbes over a twelve-month growing season and will not leach from the ground.


Other elements within this slow-release fertilizer include:

Phosphorus: A highly refined, low-salt source essential for energy transfer and photosynthetic systems within the tree or shrub.


Potassium: A highly refined "no salt" source is needed for carbohydrate formation, photosynthesis, and protein synthesis. Potassium helps achieve this and also increases water absorption and frost resistance.


Iron, Copper, Manganese, and Zinc: These secondary elements function primarily as a part of the enzyme system, essential for various energy transfers, assimilation, and growth processes in the plant.


Humates: Organic, highly decomposed plant and microbe material that adds and stimulates organic activity in the soil. Humates improve nutrient uptake and water-holding capacity. All these elements, in combination and applied at the recommended rate, constitute the single best application you can do for your trees and shrubs.


In the urban landscape, soils become compacted and therefore lack oxygen and need aeration. The ideal application for nutrients is soil injection under pressure, achieving a three-fold purpose: deep root watering, aeration, and fertilization. Understanding that trees and shrubs with good nutrient supplies can withstand disease, insect infestations, and extreme weather conditions is essential. Our fertilization practices are a preventative measure to maintain the plants in your landscape.

Do I Need to Fertilize My Trees?

To help understand why an urban tree needs fertilizer, let's compare a tree in your yard to one in the forest. We give trees planted in a yard much more care than a forest tree. Why? Let's first examine the planting site and its parent soil. The urban tree has been planted in disturbed soil and may not have topsoil or organic material. Often these soils are wet, with very poor aeration, high clay content, and very low in coarse materials such as sand or silt. 


Meanwhile, out in the forest, the soils have not been disturbed. Leaves drop each year to add a continuing supply of organic material. Microorganisms work to break down leaves and other vegetation into humus and mineral elements. Earthworms mine the soil and aid in soil aeration. 


There is no construction equipment or foot traffic to compact the soil. Drainage has not been interrupted by underground construction, compacted soils, or grade changes. Tree roots don't have to compete with the lawn for water and nutrients. 


It's no wonder trees grow so well in the forest!


We must take the necessary steps to provide the best growing conditions possible for our urban trees, including fertilizing. The liquid root fertilization process provides essential elements for healthy, vigorous tree growth and increases resistance to insects and disease. Give your trees and shrubs the tender, loving care they deserve. Contact Flat Plains Services Inc for your tree fertilization needs today!
