How to Get Rid of Daylilies

Introduction (How to Get Rid of Daylilies):

Daylilies, known for their vibrant blooms and hardy nature, can sometimes become unwelcome in a carefully curated garden. If you find yourself in a battle against daylilies taking over your garden space, fear not. This comprehensive guide will walk you through proven strategies for effectively removing daylilies and reclaiming the beauty of your garden.

Understanding Daylilies:

Before diving into removal methods, it’s essential to understand the enemy. Daylilies (Hemerocallis) are perennial plants known for their attractive, trumpet-shaped flowers and adaptable nature. While they can enhance the aesthetic appeal of a garden, their vigorous growth and spreading habits can quickly turn them into garden invaders if left unchecked.

Why Remove Daylilies?

While many gardeners believe in daylilies, there are valid reasons for wanting to remove them:

Overcrowding: Daylilies tend to multiply rapidly, leading to overcrowding issues that can stifle the growth of other plants in your garden.

Invasive Nature: Some daylily varieties are more aggressive than others, spreading rapidly and outcompeting neighboring plants for resources.

Aesthetic Preferences: As your garden evolves, your aesthetic preferences may change. If daylilies no longer fit your vision, it’s time to consider removal.

Now that we understand why daylilies are removed, let’s explore effective strategies to reclaim your garden.

Methods for Removing Daylilies:

Hand Digging:

Begin by watering the soil around the daylilies to make digging easier. Use a sharp spade or shovel to dig around the base of the daylilies, ensuring you get as much of the root system as possible. Gently lift the daylilies from the ground, shaking off excess soil.

Dividing and Transplanting:

To preserve some daylilies, consider dividing and transplanting them to a different area. Dig up the entire clump of daylilies and separate them into smaller divisions, ensuring each has roots attached. Transplant the divisions to a new location with well-draining soil.

Smothering with Mulch:

Cover the daylilies with a thick layer of organic mulch made of straw or wood chips. This method deprives the daylilies of sunlight, hindering their growth. Monitor the area and replenish the mulch until the daylilies are suppressed.

Herbicide Application:

Select a herbicide specifically designed for perennial broadleaf weeds. Follow the manufacturer’s instructions for application, ensuring you apply the herbicide when the daylilies are actively growing. Be cautious not to spray nearby desirable plants, as herbicides can be non-selective.


Cover the infested area with clear plastic, securing the edges to create a sealed environment. The heat generated under the plastic will kill the daylilies and their seeds. Leave the plastic in place for several weeks during hot, sunny weather.

Repeated Mowing:

Regularly mow over the daylilies to weaken and eventually eliminate them. This method requires patience, as it may take several mowing sessions to achieve desired results.

Vinegar Solution:

Mix a solution of white vinegar and water (1:1 ratio). Spray the solution directly on the daylilies, targeting the foliage. Exercise caution, as vinegar can be non-selective and harm surrounding plants.

Soil Solarization:

This method utilizes the power of the sun to heat the soil and eliminate daylilies. Wet the soil thoroughly, cover it with clear plastic, and secure the edges. Leave the plastic in place for 4-6 weeks during the hottest part of the summer, effectively sterilizing the soil and preventing daily regrowth.

Use of a Sod Cutter:

A sod cutter can be employed to remove daylilies by slicing through the roots and rhizomes. This method is adequate for large infestations and can quickly clear a designated area. After cutting, remove the sections of sod containing the daylilies and dispose of them properly.

Introduction of Natural Predators:

Introducing natural predators, such as certain insects or animals that feed on daylilies, can be eco-friendly. Conduct thorough research to identify potential predators that won’t harm other plants in your garden. Implementing this strategy may take time, but it can contribute to a balanced and sustainable ecosystem.

Monitoring and Maintenance:

Regularly monitor the treated area for any signs of daily regrowth. Promptly remove any new shoots or plants to prevent them from establishing and spreading. Stay vigilant, especially during the growing season, to ensure the long-term success of your daily removal efforts.

Fertilization and Soil Amendments:

Adjusting the soil conditions can impact the growth of daylilies. Avoid over-fertilizing, as this can encourage daily growth. Instead, focus on balanced fertilization for desired plants. Amend the soil with organic matter to improve its structure and nutrient content, creating an environment less conducive to daily proliferation.

Engage in Community Sharing:

If you have successfully removed daylilies and have excess plants, consider sharing them with other gardeners. Community sharing helps fellow gardeners and prevents discarded daylilies from becoming a nuisance in other locations.

Consult with a Professional Gardener:

If your daily infestation proves challenging, seeking advice from a professional gardener or horticulturist can provide valuable insights. They can assess your situation and recommend tailored strategies for effective daily removal.

Post-Removal Planting Strategies:

After successfully removing daylilies, consider implementing a thoughtful planting strategy to prevent their return. Choose plant varieties known for vigorous growth and can outcompete any potential daily regrowth. Opt for groundcovers, dense shrubs, or ornamental grasses to create a barrier against daily intrusion.

Mulching for Prevention:

Apply a layer of mulch around your desired plants and garden beds. Mulch not only conserves moisture and suppresses weeds but also inhibits the growth of daylilies by blocking sunlight and preventing their seeds from germinating.

Regular Weeding Practices:

Incorporate regular weeding into your garden maintenance routine to promptly remove emerging daylilies or other unwanted plants. Hand-pull small shoots or use appropriate weeding tools to maintain a weed-free environment.

Utilize Landscape Fabric:

Landscape fabric can serve as an effective barrier against daylilies. Install the fabric around existing plants and flower beds, completely covering the soil surface. Cut holes in the fabric for desired plants and secure the edges to prevent daylilies from finding a way through.

Install Physical Barriers:

Create physical barriers, such as edging or borders, to contain daylilies and prevent their spread. Materials like metal, plastic, or wood can create durable and aesthetically pleasing borders.

Educate Yourself on Daylily Varieties:

Please familiarize yourself with different daily varieties and their growth habits. By understanding the characteristics of specific daylilies, you may decide which variety to buy with the knowledge to include or avoid in your garden.

Practice Responsible Disposal:

Dispose of removed daylilies responsibly to prevent accidental spreading. Bag and discard them by local waste disposal guidelines, or consider composting in a controlled environment.

Stay Informed About Local Regulations:

Some regions may have regulations regarding removing or disposing of certain plant species. Stay informed about local guidelines and regulations to ensure your removal methods comply with environmental and legal standards.

Document Your Garden’s Evolution:

Keep a garden journal to document your removal process and the subsequent changes in your garden. Record observations, challenges, and successes, providing valuable insights for future gardening endeavors.

Share Your Experience with Fellow Gardeners:

Share your journey of daily removal with fellow gardeners in your community. Discuss your challenges, successes, and the most effective strategies in your environment. Conversations with other gardeners can provide valuable insights and create a supportive network.

Participate in Gardening Workshops or Events:

Attend local gardening workshops or events to expand your knowledge and learn about innovative techniques for maintaining a daylily-free garden. Networking with experienced gardeners and professionals can offer additional tips and tricks.

Consider Professional Landscaping Services:

If you find the task overwhelming or the daylilies have extensively invaded your garden, seeking professional landscaping services is a viable option. Professional landscapers can assess the situation, provide expert advice, and implement efficient removal strategies tailored to your garden’s needs.

Implement a Rotational Planting Schedule:

Implement a rotational planting schedule to deter daylilies from re-establishing in the same areas. Regularly changing the plant composition in different garden sections disrupts the conditions favorable to daily growth.

Test and Adjust Soil pH:

Daylilies thrive in a wide range of soil pH levels. Testing your soil’s pH and adjusting it to the optimal range for your desired plants can create an inhospitable environment for daylilies. Most plants prefer slightly acidic to neutral soil so that amendments can be made accordingly.

Create Distinct Garden Zones:

Designate specific zones in your garden for different plant types, creating distinct areas for flowers, shrubs, and vegetables. This organization can help control the spread of daylilies and maintain a well-structured and visually appealing garden.
