How often should you reapply Spruce Weed & Grass Killer?

Reapply Spruce Weed & Grass Killer as needed when weeds remain active, spots were missed, or new growth appears. Allow the first application time to work and always follow the product label directions.
If you have ever stared at a stubborn weed and thought, 'Really, are you still here?' you are not alone. Knowing when to reapply weed killer can make the whole process feel a lot less annoying and a lot more manageable.

The best timing for a second application

The easiest approach is to let the weed show you what it needs. For best results: Use at the first sign of weed growth. Apply when sunny and temperature is above 60 degrees F. Spray the entire weed, including leaves and stems, until all visible parts are thoroughly wet. Reapply as needed.

That means you do not need to guess on a rigid schedule. If the weed is drying out, let the product keep working. If you see missed spots or fresh growth, treat those areas again.
