If you’re gearing up for summer gardening, you’ll want to check out the Preen Garden Weed Preventer that’s currently stocked at Costco. This is one of those products that can save you countless hours of frustration down the line.
Preen is a pre-emergent weed control product that stops weeds before they even sprout. It works by creating a barrier in the soil that prevents weed seeds from germinating, though it won’t kill existing weeds that are already growing. The Costco pack gives you serious coverage for flower beds, vegetable gardens, and around trees and shrubs.
Here’s the real talk: pre-emergent weed preventers require some timing to work properly. You need to apply this before weeds start growing, and it works best when watered in thoroughly. But if you get the timing right, you’re looking at up to three months of weed prevention, which means a lot less time on your knees pulling dandelions in July.
Key Features:
- Item #: 1272331

Bottom Line: If you’re serious about keeping your garden beds weed-free without spending every weekend pulling them by hand, this is a solid investment. Just remember it’s prevention, not cure—so you’ll still need to deal with any weeds that are already established before applying.
