Apply spring pre-emergents when the 5 day average soil temps are in the 50-55F range. Or use [this tracker](https://gddtracker.msu.edu/).
If you have a question about pre-emergents, read the entire label. If you still have a question, read the entire label again.
Pre-emergents are used to prevent the germination of specific weed seeds. They don’t kill existing weeds.
Most broadleaf weeds you see in the spring can’t be prevented with normal pre emergents. You’d need to apply a specialty broadleaf pre emergent in the FALL.
