This stuff really works!

It works by creating a barrier in the soil that prevents weed seeds from germinating, making it an effective tool for maintaining weed-free flower beds, vegetable gardens, and walkways.
It is available in granular form and is typically applied to the soil and then watered in (or time is just right with a late Spring snowstorm) to activate its weed-blocking properties. While it does not kill existing weeds, it significantly reduces future weed growth, saving you a lot time and effort in keeping weeds down.
Preen is available in various formulas, including options safe for use around vegetables, flowers, and shrubs. Some versions even contain fertilizers to nourish plants while preventing weeds.
It is important to follow application instructions carefully, as improper use can affect desired plants.
While effective, Preen is best used as part of a broader weed management strategy that includes mulching and hand-pulling stubborn weeds. If you add Preen into your regular garden care, you'll enjoy a healthier, low-maintenance landscape with fewer unwanted plants competing for nutrients and space.
