re: Safe to spray Celsius?

Celsius is a systemic herbicide - it has to translocate through the plant and into the root system. it takes time to work. Don’t re-spray after a week - you could damage your lawn grass. Wait a minimum of 3 weeks, before even thinking of re-spraying.

I agree with this, but I’ll also say while it’s slower than round up it is usually noticeable in a couple of days. I have a good bit of chamberbitter and dollar weed. It kills both quickly if the right amounts are used. It’s also easy to tell what was missed, as some will die quickly and others won’t.

So if the OP has nothing dying I guess he should wait, but he likely used not nearly enough. But if he has some stuff dying he could go and just spot spray.
