Deep root feeding and watering

Ross Tree Tri-level Tree Fertilization Program Denver main

Tri-Level Tree Fertilization program

 

Since trees are not native to the Denver area, it makes sense that they might need some extra care to thrive here. Ross Tree offers a tree health care program called Tri-Level Tree Fertilization that better fits the needs of trees growing here. We now do 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 unique weather events. Why not call a licensed, insured, trusted tree deep root fertilization and watering company with an A+ BBB rating? For convenience, we accept all major credit cards.

The Tri-Level Tree Fertilization formulation supports healthy tree growth, which saves money in the long run because robust trees need less care. The fertilizer component adds nutrients and soil conditioners to promote root growth and vigor. Next, we add water adjuvants to improve product coverage, adhesion, and absorption. Lastly, we add fungi and micronutrients to increase the uptake of the nutrients. Our formulation does not include nitrogen because this element promotes excessive, unruly growth.

Applications Schedules


Winter Feeding (January to April):
The winter feeding invigorates vascular tissue growth and helps protect trees from freeze damage.

Summer Feeding (May to August): The late spring feeding helps trees leaf out. Surfactant agents reduce the surface tension, spreading the product evenly and increasing nutrient uptake by root systems. Healthy trees compartmentalize damage better, ward off insects, and tolerate Denver’s dry summer months.

Fall Feeding (September to December): The fall feeding helps trees set leaves and flower buds as the growing season ends. The nutrients help trees heal any damage and support root elongation and growth.

About timing: we can’t guarantee a specific time — our arborist is usually out after 10am, and the day’s route isn’t set until that morning. The good news: you don’t need to be home for the visit. If you’d prefer, we can have him call you when he’s on his way.
