Lawn Fertilization and Treatment questions, answered by experts

The best time to top dress your lawn depends on what type of grass you have and what climate you live in. Cool-season grass should be top dressed in late fall, while warm-season grass should be top dressed in late spring.

Custom fertilization considers grass type, soil condition, and climate, optimizing growth and reducing pests or diseases while improving overall landscape aesthetics.

Your lawn will have visible signs if it needs fertilizing. If your grass looks discolored, is slow growing, looks thin, or your yard has bare spots, then it probably needs to be fertilized to give it the nutrients it's lacking. You should also keep an eye out for weeds and pests because they can also be signs of a struggling lawn.

A lawn that suddenly and quickly turns yellow is typically the result of a dramatic change in the grass's environment. Heavy rainfall can dilute soil nutrients, rapidly yellowing the grass, and dull lawn mower blades can dry out and damage the grass in a short time. Over-fertilizing can yellow a lawn within a matter of days. 

Some things you can do to prepare for yard work services are aerate the soil, fertilize your grass, keep weeds under control, regularly mow your lawn, and water your grass.
