Frequently Asked Questions
Which grass types is Celsius safe for?
Celsius is safe for all warm season grasses other than Bahiagrass.
Does Celsius need to be watered in?
No. Celsius works via foliar uptake. Simply spray the weeds you're targeting and allow it to dry.
Can I apply granular fertilizer or CarbonizPN-G on the same day as Celsius?
Yes. We recommend that granular fertilizer and CarbonizPN-G be applied before Celsius.
Can I apply other liquids and Celsius on the same day?
Yes. We recommend applying non-herbicide products like like biostimulants and Primo Maxx growth regulator prior to spraying Celsius.
How long does it take for weeds to die after spraying with Celsius?
It depends on the weed being targeted and temperature. Most weeds begin to yellow within 14 days of application.
Are there temperature restrictions with this product?
No. We don't recommend spraying your lawn with Celsius when temperatures exceed 90F as temporary injury may occur.
How long should I wait before resuming mowing?
For best results do not mow 2 days before application and 2 days after. For example, if you plan to spray Celsius on Saturday, your last mow would be on Thursday. You would resume mowing on the following Tuesday.
