To use preen, you’ll first need to remove any existing weeds. Preen is a pre-emergent herbicide which means that it stops weed seeds from germinating. It won’t kill weeds that have already established themselves (for this job you’ll need a post-emergent). 

It’s also worth noting that preen is non-selective and can also kill vegetable, flower, and grass seeds and young seedlings. If you are using preen in a vegetable plot, spread it after your vegetables have become well established. 

Preen contains the chemical trifluralin, which creates a barrier between seeds and the soil to stop weeds from growing. 

Once you’ve prepared the ground, simply spread the granules over the soil in your garden beds. You’ll want to cover the entire area, but be sure not to overdo it, as this can harm your plants. Water the area thoroughly after applying preen and allow it to dry before replanting.

Preen should be applied before planting season to prevent weeds from germinating. Be sure to read the label carefully and follow the instructions for best results.

It’s also a good idea to wear gloves, long pants, and sleeves when using chemical products. This will prevent you from getting preen on your skin. After applying preen, it’s also a good idea to check the surrounding area. Don’t leave any loose preen granules on your patio, paths, or driveways. These can be swept up. 

You can use preen every 9 to 12 weeks as needed. Reapplying herbicides regularly will help you keep your garden weed free throughout the growing season.

How to Use Preen

Rather than using preen, you could put mulch around your vegetables, flowers, or plants. A thick layer of mulch will stop weeds from growing and will also have the added benefit of keeping moisture in your soil. This is particularly beneficial in hot areas. Mulch will also rot down and add nutrients to the soil, which will help plants grow. 

There are many varieties of post and pre emergent herbicides on the market. You can choose one that suits the weeds in your yard, as organic gardening can be more time-consuming.
