PestX Colorado provides a complete Weed Control and Fertilization Program designed for Colorado’s tough soil conditions, short growing season, and aggressive invasive weeds.
Using a combination of selective herbicides, non-selective herbicides, granular fertilizers, and integrated mechanical controls, we deliver healthier, greener, thicker lawns — while removing the noxious weeds required by Colorado law.
Our service aligns with top competitors like TruGreen, Naturalawn of America, Lawn Doctor, FitTurf, Weed Man, and others, but uses a protocol customized for Colorado’s 26-week growing season (April–November).
Colorado maintains three official Noxious Weed Lists (A, B, and C) defined by the Colorado Department of Agriculture.
These species:
Damage ecosystems
Spread aggressively
Reduce property value
Harm native vegetation
Landowners are legally required to treat or eradicate these weeds to remain compliant with city, county, and state ordinances.
We treat all three Noxious Weed List categories, including:
African Rue
Bohemian Knotweed
Cypress Spurge
Dyer’s Woad
Giant Salvinia

PestX Colorado uses a full IPM strategy, combining:
Herbicides (selective + non-selective)
Granular fertilizers
Fungicides (as needed)
Insecticides for grubs & mites
Mechanical controls (hand-pulling, mowing, aeration, seeding)
Soil amendments/pH balancing
This balanced approach produces the healthiest, densest turf capable of naturally resisting weeds.
Uses inorganically derived chemicals, offering maximum weed control and fast fertilization results.
Uses natural or organically derived chemicals.
Less potent, more environmentally aligned, and ideal for eco-conscious customers.
The client has both options.
Our program consists of:
Monthly herbicide treatments
7 rounds of granular fertilizers
Selective herbicides for turf
Non-selective herbicides for rocks, mulch, and hardscapes
Insecticide applications for grubs & mites
Optional fungicide treatments
Optional soil amendments (phosphorus, sulfur, micronutrients)
This mirrors professional programs from TruGreen and Weed Man — tailored to Colorado’s climate.

Mechanical controls are essential in Colorado turf management:
Grass must be maintained at 3.5–4 inches weekly for optimal density.
Performed at the beginning and end of the growing season to improve nutrient uptake and root health.
Weeds larger than 8–12 inches must be manually removed to prevent seeding.
Water 1–2 times per day during heat
Best in early morning or evening
Deep watering is recommended
Irrigation should be cycled properly
