Tree Fertilization in Denver, Aurora and Centennial, CO

Customized Nutrition by Professional Aborists

Fall and Spring Tree Fertilization Services

Fertilization adjusts the pH and nutrient level of the tree’s soil to maximize the tree’s health. By fertilizing in the fall, as trees are drawing in storable water and nutrient for winter, your trees will be powered up and remain healthy over the winter months until spring comes back around. Spring fertilizing helps increase the tree’s growth and vitality during the summer.    Routine fertilization ensures that your trees will be beautiful and strong all year long. 


Customer Testimonial


I’ve used them for the past 8 years for lawn and tree care. Their prices have been fair and their crews polite and professional. Derek, the owner, has always been responsive to my questions and I’ve always felt valued as a customer. Several years back my wife was feeling guilty about having to cut down a healthy tree (the roots were starting to affect a water line) and Ironwood’s crew actually spent a little time trying to make my wife feel better. Corny story, but true. I think they may have had some recent scheduling issues, but it was only a hiccup that I think they’ve fixed. Great small business I’m glad I can support.
