The Best Herbs to Plant in Your Garden to Control Weeds
Creating a lush, healthy garden often involves a constant battle against invasive weeds. While traditional methods of weed control include mulching, hand-pulling, and the use of herbicides, planting certain herbs can offer a natural and aesthetically pleasing solution. Many herbs have growth habits or properties that suppress weeds, allowing you to enjoy a beautiful and functional garden without the constant hassle of weed control. Here are some of the best herbs to plant in your garden to help keep weeds at bay.
1. Thyme
Description: Thyme is a low-growing, aromatic herb that forms a dense mat, making it an excellent ground cover. It thrives in full sun and well-drained soil, and it's incredibly drought-tolerant once established.
Weed Control Benefits: Thyme’s dense growth habit prevents sunlight from reaching the soil, thereby suppressing weed seed germination. Its aromatic foliage can also deter some pests.
Varieties to Consider: Creeping thyme (Thymus serpyllum) and woolly thyme (Thymus pseudolanuginosus) are particularly effective for ground cover.
2. Oregano
Description: Oregano is a hardy perennial herb with sprawling growth. It prefers full sun and well-drained soil, and it’s known for its aromatic leaves used in cooking.
Weed Control Benefits: Oregano spreads quickly, creating a thick cover that crowds out weeds. Its robust root system also helps stabilize soil and prevent erosion.
Varieties to Consider: Greek oregano (Origanum vulgare var. hirtum) is known for its strong flavor and vigorous growth.
3. Mint
Description: Mint is a vigorous, aromatic herb with a spreading habit. It grows well in full sun to partial shade and moist, well-drained soil.
Weed Control Benefits: Mint’s aggressive growth habit and rapid spread can outcompete many weeds. However, it’s important to plant mint in containers or designated areas to prevent it from becoming invasive.
Varieties to Consider: Peppermint (Mentha piperita) and spearmint (Mentha spicata) are popular choices for culinary use and ground cover.
4. Lemon Balm

Tips for Planting Herbs to Control Weeds
Soil Preparation: Ensure the soil is well-drained and enriched with organic matter. Proper soil preparation helps herbs establish quickly and compete with weeds.
Spacing: Plant herbs closely to maximize their weed-suppressing benefits. Dense planting reduces the amount of sunlight reaching the soil, hindering weed growth.
Mulching: Use organic mulch around herbs to further suppress weeds, retain soil moisture, and regulate temperature.
Maintenance: Regularly harvest and prune herbs to maintain their shape and encourage dense growth. This practice also prevents herbs from becoming too invasive.
Combining Herbs: Consider planting a mix of these herbs to create a diverse and visually appealing garden. Each herb’s unique properties can complement others and enhance overall weed control.
Integrating these herbs into your garden not only enhances its beauty and functionality but also provides a natural solution to weed control. By choosing herbs that spread quickly and create dense ground cover, you can reduce the need for chemical herbicides and labor-intensive weeding. Embrace the power of nature with these versatile and aromatic herbs, and enjoy a thriving, weed-free garden in the process.
