Weed Control

Our pre-emergent lawn fertilization round begins March 13th and will be available through April 15th depending on the weather.  Sign up today for the most important fertilizer application of the year.

Pre-emergent lawn weed control helps prevent broadleaf weeds before they are established. While labeled a weed killer,  more simply it stops the seeds of common Colorado lawn weeds from being established.

Pre-emergent is applied in early spring before the soil temperature reaches around 55°. By stopping weeds before they emerge, your lawn will have fewer weeds and less need for spot spraying of a contact weed killer. We’ve seen the results over and over again.

What happens is, as the weather becomes warmer, it signals grass and weeds to come out of dormancy, start gathering nutrients, and initiate photosynthesis. If broadleaf weeds become established, they basically out-compete and crowd out grasses.  The pre-emergent turns this around and allows grass to establish and use nutrients in the soil by slowing or preventing broadleaf weeds from growing.

However, there is an important role for you. Pre-emergent, in its granular form,  is activated by water which is one of the issues for timing a proper application. While it is water-activated in its granular form, the timing of the application is best done before most folks have their sprinklers turned on.  An unactivated pre-emergent will gradually lose its potency if exposed to sun and mild spring days.

So if your lawn service comes by to apply pre-emergent weed control, and your sprinklers aren’t on (and there’s no rain), it’s important to hand-water your lawn to activate the granules.

Liquid pre-emergent is available, too, with the advantage of quicker entrance into the soil zone. However, it’s more costly, and will temporarily stain the lawn with a yellowish color until it has leached into the soil.

Common Weeds

ArborScape Has Encountered Many Common Weeds In The Colorado Area. Identifying The Weeds That Are Competing With Your Turf Is The First Step In Proper Treatment And Eradication. As With Your Health, Your Lawn’s Health Will Require Proper Diagnosis Before A Treatment Can Be Suggested.

Crabgrass Is A Warm-Season Yearly Weed/Grass That Reproduces By Seed.  Along With Dandelions, Crabgrass Is Considered One Of The Hardest Weeds To Control Due To Their Ability To Produce Over 150,000 Seeds Per Plant! Crabgrass Can Be Found In Almost Every Situation And Place Including Lawns, Gardens, Golf Courses, And Cracks In The Cement. It Can Tolerate High And Low Temperatures As Well As Germinate When Mowed Down To 1/2 Inch. Cultural Practices To Mitigate Crabgrass:

  • Seed In Late Summer For New Lawns.
  • Mow Your Lawn Down To 2 – 3 Inches
  • Water Heavily Once A Week
  • Fertilize And Apply Weed Killer In Spring And Fall.

While Your Children May Think Of Them As Flowers, Dandelions Are Tenacious Broadleaf Weeds That Are Extremely Difficult To Control. Above Ground, Dandelions Spread Seeds That Ride The Winds Only To Drop On Your Lawn To Propagate Themselves.  While Underground, They Have Up To 10″ Long Taproots.  If Any Piece Of The Taproot Remains The Plant Will Fully Regenerate.

What Makes Bindweed Difficult To Control Is Their Extensive Root Systems. Bindweed Roots Will Spread Along The Ground Until Reaching A Structure. It May Then Start To “Vine Up” The Structure. Pulling Bindweed Rarely Kills The Weed Due To Its Extensive Root Structure. Bindweed Needs Several Applications Of Herbicide Every Year To Receive The Best Results.  If You Can Afford Only One Application, Make Sure It’s In Late Summer/Early Fall.

When Identifying Clover, Look For White Flowers In Your Lawn That Are Frequented By Bees.  Clover Is The Most Common Low-Growing Perennial Lawn Weed, Found In Climates All Over The Country. Because Clover Is A Small, Grass-Like Plant, Hand Removal Would Be Tedious And Time-Consuming. Most Weed And Feed Programs Should Be Able To Do Away With Clover Weeds If The Applications Are Kept Up.

Bull Thistle Is A Widespread Biennial That Is Located All Over The Country. The Bull Thistle Has A Frightening Appearance With Spikes That Come Out Of Every Part Of It. Despite Their Exaggerated Appearance, They Are Much Easier To Control Than Most Weeds. Like Other Lawn Weeds, Thistle Reproduces From Seeds. But It Must Clear A Couple Of Inches From The Soil Line, To Send Off Its Seeds.  Regularly Cutting Thistledown Will Eventually Kill Them Off.  Another Option Is To Put On Some Heavy-Duty Gloves And Pull Them Straight Up From The Ground.
