Herbicide Use Around Laurel Hedges: What to Avoid

by

Laurel hedges are a popular choice for creating privacy screens and adding aesthetic appeal to gardens. However, their delicate foliage and roots require careful management, especially when it comes to herbicide use. Improper application can damage the hedge and harm the surrounding environment.

Understanding Herbicides and Laurel Hedges

Herbicides are chemicals designed to control or eliminate unwanted plants. While they can be effective for weed management, not all herbicides are safe for use around laurel hedges. It is essential to choose the right product and apply it correctly to avoid damaging your hedge.

Herbicides to Avoid Near Laurel Hedges

  • Glyphosate-based products: While widely used, glyphosate can cause damage to laurel foliage if it drips or sprays directly onto the leaves.
  • 2,4-D and MCPA: These broadleaf herbicides can harm laurel plants, which are also broadleaf evergreens.
  • Simazine and atrazine: These soil-applied herbicides can affect the roots of laurel hedges and should be avoided near the base of the plants.
  • Paraquat: Highly toxic and non-selective, paraquat can cause severe damage to any green tissue it contacts.

Safe Practices for Herbicide Use

If herbicide application is necessary, follow these guidelines to protect your laurel hedge:

  • Use targeted, selective herbicides that are safe for broadleaf plants.
  • Apply herbicides carefully, using a brush or sponge to limit contact with the hedge foliage.
  • Avoid spraying during windy conditions to prevent drift onto the hedge.
  • Apply herbicides directly to weeds, keeping a safe distance from the laurel foliage and roots.
  • Follow the manufacturer’s instructions regarding application rates and timing.

Alternative Weed Management Methods

To minimize chemical use, consider organic or mechanical weed control options around your laurel hedge:

  • Manual weed removal by hand or with tools.
  • Applying mulch around the base of the hedge to suppress weeds.
  • Using organic weed control solutions, such as vinegar-based sprays, carefully applied to weeds only.
  • Maintaining healthy, dense hedges to naturally outcompete weeds.

Conclusion

Proper herbicide use around laurel hedges is essential to maintain their health and beauty. Avoid harsh chemicals and follow safe application practices. When in doubt, consult with a gardening expert or local extension service to choose the best weed management strategy for your landscape.
