Like your lawn, the trees and shrubs on your property need the right nutrients to thrive. While they may seem self-sufficient, landscape trees often struggle to get what they need from compacted or nutrient-poor soil.
That’s where tree fertilization makes a big difference. It helps strengthen roots, boosts healthy growth, and gives trees the resilience they need to handle various environmental factors. Trees also have varying needs based on species, which is why it’s best to leave fertilizing to the pros.
Senske provides region-specific fertilization programs designed to deliver the right nutrients at the right time. Your trees and shrubs will stay vibrant, resilient, and beautiful year-round with expert care.
Tree fertilization gives trees and shrubs the nutrients they may not get naturally from the soil. In developed landscapes, where soil is often compacted or stripped of organic matter, trees can struggle to absorb enough nitrogen, phosphorus, potassium, and iron, which are all vital for growth and health.
There are two main ways to fertilize trees:
Regular fertilization helps trees grow stronger, develop healthier canopies, and resist pests, disease, and weather stress. It’s a simple way to protect your landscape investment and keep your trees looking their best year after year.
Consistent fertilization improves the appearance of your landscape and strengthens plants from the inside out. It is one of the best ways to keep your landscape healthy, vibrant, and long-lasting.
Here are some of the key benefits of tree and shrub fertilization:
Knowing the best time to fertilize trees and shrubs can make all the difference in how well they respond to treatment. Early spring and late fall are the most effective times for tree fertilization. That’s when root systems are most active, either preparing for a new season of growth or storing nutrients for winter.
In spring, fertilizing helps trees and shrubs break dormancy with the energy they need to produce healthy leaves and branches. Fall fertilization, on the other hand, supports root growth and recovery after a long, hot summer.
We recommend avoiding mid-summer fertilization unless specific conditions call for it. High heat and dry weather can reduce a tree’s ability to absorb nutrients. They may increase stress if fertilizer isn’t applied correctly. In these cases, careful planning and proper application techniques are essential.
Soil temperature, moisture levels, and the specific needs of your trees all play a role in determining when to fertilize trees and shrubs. That’s why timing should always be paired with expert guidance to get the most out of your fertilization plan.
Trees and shrubs grow differently by species and respond to the unique conditions of your local climate. Understanding when to fertilize trees and shrubs in your area can help maximize their health and longevity. Here’s what you need to know based on where you live:
Late March to April is ideal for spring fertilization, thanks to cool, moist soil that encourages strong root growth. A fall application in October can help trees store energy before winter. Many trees in this region also face issues like chlorosis and compacted soil, which deep-root fertilization can help correct.
Spring fertilization between April and May gives trees a solid start before summer heat sets in. Follow-up treatment in September can restore nutrients lost during dry spells. Because beetles and other pests are common here, fertilization is often paired with preventive pest treatments.
Utah’s alkaline soils often lead to nutrient deficiencies, especially in iron. Fertilizing in early spring from March to April and again in October is recommended. Deep root feeding helps bypass tough soil and prepares trees for summer heat and winter chill.
Trees often struggle with poor soil and iron chlorosis in Colorado's dry climate. Fertilizing from April to May supports healthy growth, while a second round in October or early November helps trees prepare for snow and cold. Fertilization is often combined with pest and disease protection, especially against Japanese beetles.
Even strong trees can run low on nutrients over time, and when they do, their growth and health pay the price. Here are a few common signs they may need a boost through tree fertilization:
