Manual Removal Methods: How To Get Rid Of Lily Of The Valley

Manual removal is an effective way to eliminate lily of the valley from your garden. This method involves digging up the entire plant, including the roots and rhizomes, to prevent regrowth.

To manually remove lily of the valley:

  • Put on gloves and safety glasses to protect yourself from the plant’s toxic sap.
  • Dig around the base of the plant using a shovel or trowel, taking care not to damage the surrounding plants.
  • Once you have loosened the soil around the plant, carefully lift it out of the ground.
  • Inspect the roots and rhizomes for any remaining plant parts and remove them.
  • Dispose of the plant material in a trash bag and seal it tightly to prevent the spread of seeds.

Chemical Control Methods

How to get rid of lily of the valley

When manual removal is impractical or ineffective, chemical control may be necessary to eliminate lily of the valley. However, it’s crucial to approach chemical control with caution and follow the instructions carefully to minimize risks and ensure effectiveness.

Herbicide Selection

The most effective herbicides for controlling lily of the valley contain glyphosate, a non-selective herbicide that kills all plants it comes into contact with. Other options include herbicides containing triclopyr or fluazifop-P-butyl, which are selective herbicides that target specific plant species.

Application Techniques

To apply herbicides safely and effectively, follow these steps:

  1. Read and understand the herbicide label thoroughly.
  2. Choose a calm, windless day to avoid herbicide drift.
  3. Wear protective clothing, including gloves, long sleeves, and pants.
  4. Mix the herbicide according to the label instructions.
  5. Apply the herbicide directly to the lily of the valley plants, avoiding contact with desirable plants.
  6. Dispose of empty containers and leftover herbicide properly.

Precautions and Risks

Chemical control carries potential risks that must be considered:

  • Environmental Impact:Herbicides can harm beneficial insects and other non-target organisms.
  • Groundwater Contamination:Improper herbicide use can lead to groundwater contamination.
  • Herbicide Resistance:Overuse of herbicides can lead to herbicide resistance in target plants.

Therefore, it’s essential to use herbicides responsibly and follow all label instructions to minimize these risks.

Natural Control Methods

Employing natural methods to control lily of the valley growth offers a sustainable and eco-friendly approach. These techniques aim to suppress the plant’s spread without resorting to chemical herbicides.

Natural control methods harness the power of companion planting, mulching, and other organic approaches. By understanding the plant’s growth habits and competitive relationships, you can effectively manage its presence in your garden.

Companion Planting

Companion planting involves strategically placing other plants near lily of the valley to inhibit its growth. Certain species release chemicals that suppress lily of the valley’s development or create unfavorable conditions for its survival.

  • Hostas:These large-leaved plants form a dense ground cover that blocks sunlight and moisture from reaching lily of the valley.
  • Ferns:Ferns thrive in shady, moist areas where lily of the valley prefers to grow. Their dense foliage and root systems compete with lily of the valley for space and resources.
  • Daffodils:Daffodils release a chemical called lycorine that inhibits the growth of other plants, including lily of the valley.


Mulching involves spreading a layer of organic material, such as bark chips or compost, around the base of lily of the valley plants. Mulch acts as a physical barrier, preventing light and moisture from reaching the soil, which inhibits seed germination and root development.

Thick layers of mulch also create an unfavorable environment for lily of the valley by altering soil temperature and moisture levels. This can weaken the plants and reduce their ability to spread.

Other Organic Approaches, How to get rid of lily of the valley

In addition to companion planting and mulching, other organic approaches can help control lily of the valley growth:

  • Hand-pulling:Regularly hand-pulling lily of the valley plants before they flower can prevent seed production and spread.
  • Smothering:Covering lily of the valley plants with a thick layer of cardboard or black plastic for several months can smother them and prevent their regrowth.
  • Solarization:Solarization involves covering the soil with clear plastic during the hottest months of the year. The heat generated under the plastic can kill lily of the valley roots and seeds.

Long-term Effects of Natural Control Methods:

Natural control methods for lily of the valley are generally less effective than chemical herbicides in the short term. However, they can provide long-term suppression of the plant’s growth without the negative environmental impacts associated with chemicals.

By consistently implementing natural control methods, you can gradually reduce the presence of lily of the valley in your garden and maintain a healthy and balanced ecosystem.

Preventing Future Growth

How to get rid of lily of the valley

Lily of the valley can spread aggressively, making it essential to prevent its future growth. Preventing seed dispersal and rhizome propagation is crucial, as is proper disposal and hygiene to minimize the risk of re-infestation.

Preventing seed dispersal is key. Lily of the valley produces red berries that contain seeds. These berries are attractive to birds, which can spread the seeds far and wide. To prevent this, remove the berries as soon as they appear.

Deadhead spent flowers to prevent seed formation altogether.

Rhizome Propagation

Lily of the valley spreads primarily through rhizomes, which are underground stems that produce new plants. To prevent rhizome propagation, dig up and remove any new shoots that appear. Be sure to remove the entire rhizome, as even small fragments can produce new plants.

Proper Disposal and Hygiene

Proper disposal of plant material is essential to prevent future growth. Do not compost lily of the valley plants or plant parts, as this can spread the plant to other areas of your garden. Instead, dispose of them in the trash or burn them.

Finally, practice good hygiene when working with lily of the valley. Wash your hands thoroughly after handling the plants to prevent spreading the plant to other areas of your garden or home.

Identification and Characteristics

Lily of the valley (Convallaria majalis) is a perennial flowering plant belonging to the family Asparagaceae. It is a low-growing plant with arching stems that reach a height of 15-30 cm. The leaves are lance-shaped, with a smooth margin and a pointed tip.

The flowers are white, bell-shaped, and fragrant. They are arranged in a raceme, which is a type of inflorescence with flowers arranged along a single stem. Lily of the valley prefers to grow in moist, shady areas, such as woodlands and along stream banks.

It is native to Europe and Asia, but has been introduced to other parts of the world, including North America.

Lily of the valley is a highly invasive plant that can quickly spread and form dense colonies. It is important to be able to identify this plant so that it can be controlled and removed. The following are some of the distinctive features of lily of the valley:

  • Leaves:The leaves are lance-shaped, with a smooth margin and a pointed tip. They are arranged in a basal rosette, which is a type of leaf arrangement where the leaves are all clustered together at the base of the plant.
  • Flowers:The flowers are white, bell-shaped, and fragrant. They are arranged in a raceme, which is a type of inflorescence with flowers arranged along a single stem.
  • Fruit:The fruit is a red berry that contains one or two seeds.
  • Roots:The roots are fibrous and fleshy. They can spread quickly and form dense colonies.
