Vessel 3 Way Herbicide should not be applied in temperatures below 40 degrees F or over 85 degrees F, to avoid damage to your turf. Keep in mind that 65 - 85 degrees F is the ideal temperature window for post-emergent applications when the targeted weeds are actively growing. Colder temperatures do not yield effective results as the warmer temperatures do. Please view the product label for more information.
You can refer to our Lawn Care Schedule for more recommended timing for lawn applications.
