Start Managing Lawn Health Now With Your Denver Landscaping Service

March 3, 2016

The unpredictable weather of March—in like a lion, out like a lamb—mimics our own spring fever. March brings a certain stir-crazy feeling that drives us outside to survey the wreckage that winter has made of our yards. In Denver, record warm temperatures this past winter make it more likely than ever that early spring conditions will be perfect to get head start on lawn care: no snow and soft ground. Take the advice of your Denver tree services and get ahead this year!


Early spring is the perfect season for aerating lawns. Aeration perforates the soil which enables air, water, and nutrients to reach the roots. Grass grows vigorously in early spring, which means that the sod can heal quickly from the perforations.

It’s best to aerate heavily trafficked areas where the soil is compacted. Compacted soil disallows proper root growth and prevents necessary absorption of nutrients, air, and water to the roots. If your lawn features mature trees and autumn leaf fall wasn’t removed, the heavy organic debris can also suffocate the grass buried beneath. Aeration will assist in the lawn’s recovery from neglect and damage.

Thick thatch may also contribute to the lawn’s poor health and appearance by preventing nutrients from reaching the roots. If your lawn feels spongy underfoot and dries out easily, test the sod for excessive thatch. A thatch layer more than one-half inch thick indicates aeration is needed. Heavily compacted areas may need repeated passes from the aerator to properly open the soil.

American Arbor Care recommends aeration before applying pre-emergent chemicals, although aerating afterward will not negate the benefit of any herbicides and fertilizers applied shortly before aeration.

Pre-Emergent Applications

Pre-emergent lawn care products eliminate weeds before they get a foothold in the lawn and add valuable nutrients to stimulate healthy, vigorous growth. We  recommend the application of pre-emergent chemicals soon after soil aeration for best effect.

Most, if not all, pre-emergent chemicals require post-application watering to deliver herbicides and fertilizers to the grass’ roots. (The chemicals do no good coating the grass blades.) The best type of pre-emergent fertilizer does not “burn” the lawn if the lawn is not watered immediately after application. American Arbor Care uses a slow-release, pre-emergent fertilizer that gives the homeowner greater flexibility in post-application watering.

A pre-emergent works on the top layer of soil where weed seeds sprout. The beauty of this type of application is that the weed seeds sprout, but the herbicide kills the young plants before they have a chance to develop roots or reproduce. Although no single application will eliminate every weed, repeated applications will vastly reduce the weeds that do grow.

Pre-emergent chemicals may pose hazards. Organic varieties may prove less irritating to people and pets with sensitive skin, but they are expensive and require more frequent application. Some chemicals may also stain concrete or stone. Check with your landscape specialist to make sure patios and foundations will not be discolored. Be aware that factors which disturb the soil, such as cultivation or moles, will hinder the efficacy of the pre-emergent application.

Even application works best, but the intent is to cover the ground consistently, not completely. We can calculate the application rate (pounds per square footage) that will work best for your lawn.
