What's the difference between killing garden weeds and preventing them?

Hi, I'm Chris Holliday. That's just one of the weed questions we're frequently asked at Preen. In this video, we'll address ome of the most common questions about dealing with weeds. Let's start with that first one.

Killing weeds is one of the most time-consuming garden jobs. You can spray them. Burn them, chop them, and dig them out, and you'll need to do it over and over again. Why not make things easier? Why not stop weeds from ever growing in the first place? Sound incredible? It's not. You can actually prevent weeds in the garden with Preen. Preen doesn't kill weeds. It acts on seeds. It stops weed seeds before they sprout. Used as directed, you can use it with confidence around bedding transplants or mature plants.

Preen weed preventers create an invisible weed-fighting barrier beneath the soil surface that keeps weed seeds from sprouting and forming roots.

No roots. No weeds. No weeding. It's that simple.

Another question involves combining Preen and mulch. Weed seeds need light to sprout. Mulch deprives them of light and prevents their sprouting. So why do we need Preen?

The war against weeds is won at the seed level. There's an old saying that one year's weeds create seven years' seeds. It's true. There are millions of dormant weed seeds buried in garden beds. Plus, garden mulch itself often contains weed seeds. Even more seeds enter the garden every day carried in by the wind and by birds and animals. Mulch is a major weed prevention tool. But mulch can't do it all.

Preen and mulch together are the one-two punch of weed prevention. Another question we hear often is what is the best way to eliminate existing weeds?

Just as Preen, when used as directed, won't affect your existing garden plants, it won't kill existing weeds. These weeds need to be eliminated. There are products that kill weeds, but then you still have unsightly dead weeds in the garden.

We recommend that weeds be manually removed from the garden, roots and all.

Ironically, removing weeds manually brings thousands of dormant weed seeds to the surface. Not a problem when you're armed with the Preen weed prevention routine.

After weeding, simply add a layer of mulch and then sprinkle on Preen weed preventer. Water it in and you're on you way to a very manageable, weed-free garden.

We hope we've answered some of your questions about dealing with and preventing weeds in the garden.
