DO put down your pre-emergent!
This application will prevent winter weeds and will help specifically in the late Winter early Spring. The weeds seen at this time are actually Winter weeds and are prevented NOW.
 
DON’T apply fertilizer!
When you hear us say “winterizing” the lawn, this is not a nitrogen based fertilizer. You do not want to apply something that is high in nitrogen, this helps feed and promote fungus. Be mindful of what you apply to you lawn right now.
