Many of us who love gardens, also love sharing them with our pets. Hi, I’m Chris Holliday. Enjoying a weed-free garden is easy with Preen weed preventers. But what about the pets who share the garden with us? Here’s what you need to know about Preen and outdoor pets.

Preen is a weed preventer. It doesn’t kill weeds. It stops them from growing before they start by preventing weed seeds from sprouting.

When you sprinkle Preen granules in the garden and water them in, Preen creates an invisible weed-preventing barrier below the surface of the soil that prevents seeds from sprouting.

Preen works on seeds. Used as directed on the label, it doesn’t affect established plants.

With pets in the picture, it’s best to water-in and activate you application right away. Keep pets and people out of the garden bed until it dries. Typically a half hour or so.

You want the Preen granules to stay where you put them, not get tracked about on paws and shoes.

As you can see, it takes very little Preen to do the job.

After the active ingredient is released and bonded into the soil, what’s left on top are these little granules made of corncob and recycled paper. Like the active ingredient in Preen, they will biodegrade into soil elements.

Pets walking in the garden will not undermine your Preen application. If a paw or foot makes a small indent in the weed barrier, it will quickly reestablish itself.

If your dog is a digger, you may need to fix things up from time to time. If your dog, or you for that matter, digs a big hole in the bed, you need to fill in the hole, and then add more mulch and Preen in that area.

Remember that digging in the garden soil unearths buried dormant weed seeds. Once on the surface they’re exposed to the sunlight they need to sprout.

If your outdoor pets happen to be koi, then you do need to take care. Preen should not be introduced to aquatic ecosystems.

And that’s it. It’s easy for you and your pets to enjoy a weed-free garden with Preen. As with any garden product it’s important to read the product label and follow instructions. You can find Preen labels and lots more easy-care gardening information on While you’re there, sign up for Preen’s email “Garden and Landscape Tips” for timely updates and ideas on gardening and outdoor living.
