Deep Root Feeding and Watering
Tri-Level Tree Fertilization Program
Denver’s climate and heavy clay soils are great for growing grass, not trees. Since trees are not native to the Denver area, it makes sense that they might need some extra care to thrive here. Ross Tree now offers a new tree health care program called Tri-Level Tree Fertilization that better fits trees’ seasonal needs. We are moving to deep root feeding three times a year versus two because Denver’s growing season is getting longer, and we are seeing more tree insects and more unique weather events.
The formulation has three ingredients that support healthy tree growth in Denver’s arid climate and heavy clay soils. The fertilizer component adds nutrients and soil conditioners that support early vigor and root growth. Next, we add adjuvants or surfactant agents to reduce spray drift and improve water conditioning. The last adds fungi and micronutrients to expand the surface-absorbing area of plant root systems, allowing greater access to nutrients and water.
Winter Feeding (January to April)
The first feeding of the year focuses on strong health growth. Our formulation does not include nitrogen, which promotes excessive growth. The feeding jumps start the vascular system and help protect trees from freeze damage.
Summer Feeding (May to August)
In May, hardwood trees need nutrients to finish leafing out. We use surfactant agents that reduce the surface tension of water, helping it spread evenly and easing nutrient uptake by root systems. Health root systems tolerate dry summer months better and support new crown growth. Any insect damage is compartmentalized, stopping it from spreading to other parts and allowing the tree to heal.
Fall Feeding (September to December)
This formulation supports leave and flower bud growth as the growing season ends. The nutrients help heal any damage and support root elongation and growth.
The three feedings reduce tress stress. Healthy trees can ward off disease and insects themselves. For a free estimate of our Tri-Level Fertilization Program, click here to fill out a request service form or call 303-871-9121.
