Preen Weed Preventer Plus Plant Food Sounds Too Good To Be True, So We Turned To Reviews

Sometimes you might come across a product that sounds suspiciously amazing. One example is the Preen Weed Preventer Plus Plant Food. At first glance, you may be thinking, "How can a product that kills weeds also feed my flowers and vegetables without killing them too?" While Preen is a well-respected brand and has one of the best crabgrass killer products on the market, in any situation where you're uncertain about something you haven't tried before, it makes sense to check out the reviews — and that's exactly what we did. After customers purchased Preen's Weed Preventer Plus Plant Food at various stores including Lowes, Walmart, and Home Depot, Google summarized their feedback and showed that the product had over 900 reviews with an overall rating of 4.5. In other words, most users found that it worked very well.

The secret to this products two-in-one function is in the fact that this is a pre-emergent herbicide. If you're not familiar with what a pre-emergent is and why you would apply it to your lawn, you should know that it's designed to stop weed seeds from germinating rather than kill any existing weeds in the garden. The active weed-control ingredient is trifluralin which is often used in commercial horticultural and agricultural enterprises as a pre-emergence herbicide. On top of that, the product is fortified with the three major nutrients; it contains 9% nitrogen, 10% phosphorus and 9% potassium, which most would regard as a balanced fertilizer.

On the whole, we found mostly positive reviews from customers. Many found that the Preen Weed Preventer Plus Plant Food did prevent weeds from growing and that it was safe to use around flowers. One customer even commented that they use this product at a grave site planted with petunias, writing: "The past years the flowers were overgrown with weeds but not this year. Not one weed and the petunias are higher and stronger than ever!" Another customer uses this product at their summer house which they only visit monthly. "Once I get the beds cleaned up in the early spring I just sprinkle Preen around and it keeps them pretty tidy all season long," she said, "I might have an occasional weed to pull here or there when we return but on the whole the beds look great."

While reviews are overwhelmingly positive, to get a balanced view, we also took a look at the negative reviews. Many of these were from customers who thought Preen's product would kill existing weeds and said it didn't work to solve their weed problem. The manufacturer often responded that Preen is a pre-emergence herbicide and won't kill existing weeds. Another dissatisfied customer stated: "It doesn't last anywhere near 3 months for weed control and my flowers weren't any bigger or better than usual." For the best chance at good results, always remember to read the instructions carefully before applying any product.
