Broadleaf Weed Control in Spring Cool Season 40° – 65°
As early spring arrives homeowners walk through their springtime lawns , they all have the same question. “What is this strange little weed?” Bare spots left from summer stressed lawns become home to broadleaf weeds. Some weeds like dandelions survive the winter, others weeds like chickweed and henbit with its purple flowers will pop up from seed in cool soils. As days get longer and soil temperatures rise the small broadleaf weeds start to spread out and capture the sun’s rays.
The best way to kill these spring weeds is a cool weather liquid weed killer. Gordon’s Speed Zone with Uncle’s Stikit, added can be used effectively during cooler spring weather. Uncle’s Stikit, a non-ionic surfactant, improves weed killing efficiency by increasing the spread and penetration of the active ingredient throughout the surface of the broadleaf weed. Humectants in Stikit extends drying time which encourages increased uptake of herbicide on broadleaf weeds. Also, be patient, at cold soil temperatures, these plants die more slowly, and you may need a second application after seven to ten days. Speed Zone is the best choice for tiny leaf weeds like chickweed, clover, veronica and henbit. Always use pesticides responsibly.

Broadleaf weed control in Fall Season 85° – 65°
Mid-September to Mid-November is an excellent time to control broadleaf weeds. Weeds like dandelions, plantain, curled dock, and thistle. In fall, broadleaf weeds are busy collecting energy from photosynthesis and storing it in the crown and roots. Loveland Weed and Feed and Speed Zone® contain systemic broadleaf weed herbicides that will move through the leaf tissue and into the crown and roots for a complete kill. Killing broadleaf weeds in fall will allow turf to fill in the bare spots before crabgrass or other weeds germinate the following spring.
