The best way to get ahead and stay ahead of garden weeds is to stop them when they’re seeds. If you stop weed seeds from sprouting, they never grow and you won’t have to pull them. Different weed seeds germinate at different times throughout the growing season: spring, summer, fall or even winter, too, in some areas. For gardeners, this can mean wave after wave of new weeds. So, while early spring is an optimal time to begin applying Preen, any time is a good time to launch a weed prevention campaign.
Get Ahead and Stay Ahead of Weeds
Step 1 - First remove any existing weeds to start the season with a clean slate. Take care to remove their roots. Preen doesn't kill existing weeds. It stops new weeds before they start by preventing their seeds from rooting.
