The last thing we want is viable weed seeds to spread to our gardens. Now is the time to apply Preen to keep late-season, winter annuals at bay. Here are five reasons to apply Preen Garden Weed Preventer between now and mid fall. Always read and follow the label directions.

• Winter annuals are sneaky plants with seeds adept at hiding in the soil, only to germinate and emerge late in the fall and reach maturity by the time spring arrives.
• In Spring, we are all busy spiffing up the landscape after its winter rest. An application of Preen in early fall reduces weed-pulling chores, and prevents competition for spring-blooming bulbs and perennials.
• Ugly brown weeds next to the tulips? I don’t think so. Preen prevents weed seeds from germinating, eliminating the time-consuming need to spray and then pull them when they are dead.
• An application of Preen Natural Vegetable Garden Weed Preventer reduces unwanted competition for your late-season veggies, including lettuces, spinach, and broccoli. Preen Natural Vegetable Garden Weed Preventer is 100% corn gluten, safe for use around food and pets. Apply when seedlings are 3" tall and delete "weed worry" from your to-do list.
• You already use Preen? What about your neighbors? Countless weed seeds get blown in from nearby lawns and gardens and settle in your landscape. Preen forms a protective barrier that lasts three to four months, to keep the weeds from germinating in your garden.
