Therefore, this product is more useful for people who have just weeded their gardens and lawns and want to prevent them from growing in the future, keeping their landscapes and gardens well maintained and weed-free.

This product is well received by gardeners for its easy application process and long-lasting effects, i.e., it is not easily washed off by rain or hose water. However, Preen cannot be used on flower seeds and plants that have not germinated yet or are smaller than 2 inches since they can damage, kill, or stunt their growth.

  • Contains strong chemicals that effectively and quickly kill wild grasses and weeds
  • Ideal for aesthetic mulch areas

It is strong enough to rid your garden of almost all types of wild grasses and weeds, such as quack grass, chickweed, Bermuda grass, broadleaf weeds, bushes, purslane, spurge, nutsedge, crabgrass, among many others.

One of the best features of this weed-killing solution is that it kills the weeds and grass at their roots, saving gardeners the time and effort of having to apply it from the leaves down. This is possible because of the 41% glyphosate present in the solution, which gets absorbed by the weeds and grass, killing them at the roots.

Another great aspect of this solution is that it mixes very well with water; you can mix 3 tablespoons of this liquid in a gallon of water, and it will still be strong and efficient enough to kill the weeds that show up in your lawn.

  • Fast results
  • Does not wash off easily, which means that constant reapplication is not necessary


  •  Needs to be sprayed carefully
  • Is not pet-friendly
  • Only kills and does not prevent weed growth

The Preen extended control weed preventer prevents weed and wild grass seeds from germinating and averts their growth before they can even bud.

What makes it different from the Preen garden weed preventer is its easy-to-use bottle and flip cap, which make the application of the weed preventing solution a breeze. Moreover, as soon as you are done de-weeding your garden, you can apply it by simply spraying it the targeted areas of your lawn. Their granular structures make them easy to apply and do not damage the soil, your plants, or any sowed flower seeds.

After sprinkling the granules in the affected areas, water the treated parts of the lawn for the granules to start their function. Once you have watered the sprayed areas, the granules will be activated and will form a weed growth controlling barrier on the ground and around your plants and flowers, preventing any further weed or grass growth.

The product, like everything else, does have some downsides, too. For instance, many consumers complain that Preen only prevents the growth of any future weeds and grasses but does nothing to the preexisting weeds.

  • Advanced weed prevention solution
  • Extremely effective
  • Lasts much longer than other weed preventing liquids


  •  Only prevents weed growth and does not kill preexisting weed or grasses
