Provide Essential Nutrients for Tree Roots
It is important that trees receive the nutrients necessary to live and thrive. When your soil is deficient of nutrients, your trees will not reach their full landscape potential, will be more susceptible to disease and insect problems, and will have a shorter life than a similar, well-fertilized tree. Trees in urban and suburban environments such as Milwaukee and Brookfield are often under high stress conditions due to low moisture availability, soil compaction, physical damage, nearby construction, and competition from turf and nearby trees and shrubs. Professional root fertilization services help to combat this and give the tree the nutrients they need.
Wachtel Tree Science's specifically formulated fertilizing services provide beneficial nutrients and fungi in a variety of application techniques. Our Certified Arborists offer a thorough analysis to identify the best fertilization treatment for your landscape.

Tree Fertilization Services Based on Biological Needs
Tree fertilizing services ensures that the nutritional needs your landscape requires for healthy growth are met. Due to natural biological processes, trees are continually removing mineral elements from the soil. In a native forest, beneficial elements are recycled as leaves drop down to the forest floor and decompose. In most residential, commercial and municipal landscapes, we interrupt this process through routine clean-up maintenance. Without periodic fertilization, mineral elements will become deficient and can cause a variety of tree care concerns. Our fertilization treatments help support the nutritional needs of trees that are interrupted in the urban landscape.
Professional tree fertilization services supports the tree's ability for replacement growth, feeder root production, defense of all sorts of attacks from insects and disease, and recovery from issues. Slow release fertilizers, compost teas and the application of beneficial fungi are all services our Certified Arborists offer based on your landscape's specific needs.

Tree Fertilization Frequently Asked Questions
If my tree looks sick, should I fertilize it?
Depending on the issues going on with the tree, fertilization or other soil amendments may be recommended. Fertilization cannot cure everything, so understanding the issue is the first priority.
Are tree fertilizers harmful to pets or kids?
No, fertilizers are generally injected into the ground to be taken up by the tree’s root system.
Do trees in my yard need to be fertilized?
Trees in yards typically do not have the nutrient cycling that naturally occurs in a wooded setting. Often, trees will benefit from replenishing these lost nutrients through fertilization and other methods.
What’s the difference between synthetic and organic fertilizers?
Synthetic fertilizers are man-made. Organic fertilizers come from natural sources such as plant and/or animal sources.
Should I fertilize a newly planted tree?
Nitrogen fertilizers are generally not recommended for the first year of establishment. There are other options to help new trees redevelop roots lost in the planting process.
Is it possible to use too much fertilizer?
Yes, too much can cause problems for trees and soil. Following the rates on the product label is important.
Does it really matter what time of year you fertilize a tree?
Yes, timing is an important factor for fertilization. Our ISA Certified Arborists can provide the best option for you and your trees.
