Preen is a popular weed-control product that many gardeners use to keep weeds from taking over their vegetable gardens. But is Preen safe to use around vegetables? Here’s what you need to know.

What Is Preen?

Preen is a pre-emergent herbicide that was developed to kill weeds before they have a chance to grow. It contains an active ingredient called trifluralin, which is safe for use in garden settings. It has a wide range of applications, and is widely used to control a range of grasses and broadleaf weeds.

Is Preen Safe for Vegetable Gardens?

Yes, Preen is safe to use in vegetable gardens. It will not harm vegetables, fruits, shrubs, or ornamental plants. It also won’t harm beneficial insects, like bees and ladybugs. In fact, it is approved for organically-certified vegetable gardens. That said, it is important to use it according to instructions and precautions to ensure it does not cause any harm.

How to Use Preen in a Vegetable Garden

It is important to use Preen with care, so it only kills the weeds and does not harm your vegetables. Here are some tips for using Preen safely in a vegetable garden:

  • Only use Preen after your vegetables have begun to grow. Preen should never be used on newly-planted seedlings since it will kill any young plants it comes into contact with.
  • Be sure to thoroughly read the instructions before using. Pay particular attention to the amount of product to use and how often it should be applied.
  • Keep Preen away from vegetables. Be sure to apply it to the soil, avoiding any contact with vegetables.

In short, yes, Preen is safe to use in a vegetable garden, as long as it is used according to the instructions. It is a great way to control weeds without harming your vegetables, fruits, and other plants. With the right precautions and attention, you can have a weed-free vegetable garden in no time.
