Kurt from Huntsville, Al writes
If I apply in Fall, it tells to follow up with another treatment 45-90 days later. If you do that, will there be a need to re-apply a pre emergent in the spring?
The need for a spring application of a pre-emergent is almost always needed, but it truly is going to be dependent on the weeds you are primarily looking to prevent and when they germinate the most in your area. You can often consult with your local cooperative extension office or local master gardner to find out when the weeds you are looking to target germinate in your area for a better idea of application intervals that will best suit your needs for thorough application and results.
