How Preen Works

Preen Garden Weed Preventer stops weed seeds from growing in your lawn. It creates a barrier in the soil that kills weed seeds before they sprout.

It does not kill existing weeds, only new ones trying to grow. You apply it on the soil surface, and it works as the seeds start to grow.

Active Ingredients

Preen contains chemicals that stop weed seeds from growing. These ingredients target seeds, not grass or flowers.

The main active ingredient is pendimethalin. It prevents weed roots from developing after seeds sprout.

• Pendimethalin: stops root growth of weed seeds
• Other inert ingredients help spread and hold the chemical in soil

Application Process

Apply Preen to dry soil before weeds start to grow. Spread it evenly over the lawn surface.

Water the area lightly after applying. This activates the weed preventer and moves it into the soil.

• Apply in early spring or fall
• Use a spreader for even coverage
• Water after applying to activate

Duration Of Effectiveness

Preen works for about three months. During this time, it stops new weeds from growing.

If it rains or you water your lawn, the product stays active in the soil. After three months, you may need to apply again.

• Effective for up to 90 days
• Reapply to keep weeds away
• Lasts through normal watering and rain
