Is your yard being overrun by unruly clumps of monkey grass? You're not alone! This seemingly innocent ground cover, often planted for its low maintenance appeal, can quickly become an aggressive invader, choking out your desired plants and creating an unkempt landscape. Monkey grass, also known as liriope or creeping lilyturf, spreads rapidly through underground rhizomes, making it notoriously difficult to eradicate once it's established.
Controlling monkey grass is crucial for maintaining the health and beauty of your garden. Left unchecked, it can crowd out your favorite flowers, shrubs, and even lawn grasses, leading to a monotonous and unbalanced ecosystem. Furthermore, its dense foliage can harbor pests and diseases, potentially impacting the overall health of your entire yard. Reclaiming your garden from a monkey grass invasion requires patience, persistence, and the right techniques.

What's the best way to kill monkey grass without harming surrounding plants?
The most effective way to kill monkey grass without harming nearby plants is to use a combination of careful manual removal and targeted application of a non-selective herbicide like glyphosate, meticulously shielding desired plants during the application process. Patience and persistence are key, as monkey grass is a tenacious plant and may require multiple treatments.
Monkey grass, also known as liriope or border grass, spreads aggressively through rhizomes, making complete removal challenging. Start by physically removing as much of the plant as possible, digging down to extract the roots. This reduces the amount of herbicide needed and minimizes the potential for overspray onto desirable plants. Focus on removing entire clumps, being diligent about extracting any remaining rhizomes or root fragments from the soil. Any pieces left behind can resprout, so a thorough initial effort is essential.
Once you've manually removed as much monkey grass as possible, carefully apply a non-selective herbicide containing glyphosate to the remaining growth. Protect surrounding plants by using cardboard shields, plastic sheeting, or even dedicated herbicide shields designed for this purpose. Apply the herbicide on a calm day to prevent drift. Be precise, painting the herbicide directly onto the monkey grass leaves with a brush or using a spray bottle with a narrow nozzle. Multiple applications, spaced a few weeks apart, may be necessary to completely eradicate the monkey grass, especially established patches. After each application, monitor the area for regrowth and retreat as needed.
How do I permanently remove monkey grass roots?
Permanently removing monkey grass roots requires persistence and a combination of techniques, primarily focusing on physically removing the roots after weakening the plant. This often involves digging up the clumps, thoroughly removing all visible roots, and then either applying a non-selective herbicide to any regrowth or diligently monitoring the area for new shoots and repeatedly digging them up until the root system is exhausted.
Effective monkey grass removal starts with weakening the plant. If the area is manageable, cut the monkey grass back to ground level. Next, thoroughly soak the area with water a day or two before you intend to dig. This makes the soil softer and easier to work with, allowing you to extract more of the root system. Using a sharp spade or garden fork, dig around the perimeter of the monkey grass clump, going deep enough to undercut the roots. Lift the entire clump out of the ground. Once the clump is removed, carefully inspect the soil for any remaining roots or rhizomes (underground stems). Monkey grass can regenerate from even small pieces of root, so it's crucial to remove as much as possible. If you find it difficult to extract every last piece, consider using a soil sifter to separate the soil from the roots. After removing the bulk of the roots, you have two main options: monitor the area diligently for new growth and dig up any new shoots as they appear or apply a non-selective herbicide like glyphosate to kill any remaining roots. Be extremely careful when using herbicides, as they can harm other plants you want to keep. Repeat applications may be necessary.Will vinegar effectively get rid of monkey grass?
While vinegar *can* technically damage monkey grass, it's generally not considered an effective long-term solution for complete eradication, especially for established plants. Vinegar primarily acts as a contact herbicide, meaning it only harms the parts of the plant it directly touches. Monkey grass, with its extensive root system, can quickly recover and regrow from untreated roots.
The efficacy of vinegar depends on several factors, including the vinegar concentration (higher is better, but also more hazardous), the age and health of the monkey grass, and environmental conditions. Household vinegar (typically 5% acetic acid) might only temporarily brown the foliage, requiring repeated applications and still failing to kill the roots. Horticultural vinegar (10-20% acetic acid) is more potent but also poses a greater risk to desirable plants and soil organisms if not used carefully. Furthermore, vinegar is non-selective, meaning it will damage or kill any plant it contacts, making targeted application crucial. For a more effective approach, consider using a systemic herbicide specifically formulated for grass control. These herbicides are absorbed by the plant and translocated to the roots, providing a more thorough kill. Alternatively, manual removal, though labor-intensive, can be a successful option for smaller infestations, ensuring you dig up as much of the root system as possible. Remember to always follow product instructions and safety precautions when using any herbicide, including vinegar.Is there a natural way to control monkey grass growth?
Yes, while completely eradicating monkey grass naturally can be challenging, you can effectively control its growth and spread using a combination of cultural practices and natural herbicides. This involves diligent maintenance, strategic barriers, and the application of environmentally friendly solutions.
Consistent maintenance is key. Regularly trimming monkey grass back to your desired size will prevent it from becoming overgrown and spreading through seed dispersal. Mulching heavily around the plants with organic materials like wood chips or shredded bark can suppress new growth by blocking sunlight and physically hindering the rhizomes. Be sure to maintain a thick layer of mulch (3-4 inches) and replenish it as needed. Physical barriers, such as edging made from metal, plastic, or stone, can also be installed to contain the grass within designated areas and prevent it from invading unwanted spaces. Bury the edging deep enough (at least 6 inches) to prevent the rhizomes from growing underneath. For a natural herbicide option, consider using horticultural vinegar (acetic acid). Unlike household vinegar, horticultural vinegar has a higher concentration of acetic acid and is more effective at killing unwanted vegetation. Apply it directly to the monkey grass, being careful to avoid spraying desirable plants. Repeated applications may be necessary, especially for established patches. Another option is a homemade weed killer consisting of a mixture of boiling water, salt, and dish soap. However, be extremely cautious when using this mixture, as it will kill any plant it comes into contact with and can alter the soil pH, potentially harming beneficial soil organisms. Test it in an inconspicuous area first.What's the best time of year to eradicate monkey grass?
The best time of year to eradicate monkey grass (also known as liriope or border grass) is during its active growing season, which is generally late spring to early summer or early fall. This is when the plant is actively drawing nutrients down into its root system, making it more susceptible to systemic herbicides.
Eradicating monkey grass can be a challenge, but targeting it during its active growth phase significantly increases the effectiveness of your chosen removal method. In late spring and early summer, the plants are vigorously growing, expending energy and absorbing nutrients at a high rate. This means that any herbicide applied will be quickly transported throughout the plant, including the rhizomes (underground stems), which are crucial to kill to prevent regrowth. Similarly, in early fall, as the plant prepares for dormancy, it actively pulls nutrients down into the roots for storage, again making it vulnerable to systemic herbicides. While physical removal is always an option, it can be extremely labor-intensive and often ineffective unless you remove every single rhizome fragment. Therefore, using a systemic herbicide containing glyphosate or imazapyr, applied carefully according to the product label, is typically the most effective approach. Regardless of the season you choose, be sure to follow up with repeat applications if necessary to address any surviving plants. Proper watering of the treated area after herbicide application can also enhance the absorption of the chemical by the monkey grass.How do I prevent monkey grass from spreading into my lawn?
The best way to prevent monkey grass (Liriope or Ophiopogon) from invading your lawn is to create a physical barrier, regularly trim its spreading runners, and promptly remove any stray shoots that appear in your lawn before they become established. Consistent vigilance is key to managing its aggressive growth habit.
A physical barrier, such as edging made from metal, plastic, or stone, sunk several inches into the ground (ideally 6-8 inches) around the perimeter of your monkey grass planting, can significantly impede its spread. This barrier needs to be maintained regularly; ensure it remains intact and that monkey grass isn't growing over or under it. Regularly inspecting the barrier and addressing any breaches immediately will prevent runners from escaping.
Beyond physical barriers, diligent maintenance is critical. Monkey grass spreads through underground rhizomes and above-ground runners. Trimming these runners as soon as you see them will prevent them from rooting in unwanted areas. You can use a string trimmer or hand pruners for this task. Moreover, regularly inspect your lawn, especially near the monkey grass, and immediately dig up and remove any new shoots that emerge. The longer you wait, the harder it will be to eradicate them.
What are the long-term effects of different monkey grass removal methods?
The long-term effects of monkey grass removal vary significantly depending on the method used, ranging from complete eradication with persistent herbicide application to temporary suppression with manual removal, and each approach influences the surrounding ecosystem and future plant growth differently.
Manual removal, while seemingly benign, can lead to soil disturbance and erosion if not executed carefully. Moreover, any remaining rhizomes left in the soil will invariably lead to regrowth, necessitating ongoing maintenance and potentially altering the soil structure over time if frequent digging is required. Furthermore, the repeated disturbance can create opportunities for other, potentially more invasive, weed species to establish themselves, requiring additional management strategies. Herbicide application, particularly with systemic herbicides like glyphosate, offers the potential for complete eradication, but introduces chemicals into the environment with both intended and unintended consequences. While effective at killing monkey grass, these herbicides can also affect non-target plants if misapplied or through drift, disrupting the local ecosystem balance. Repeated use can lead to herbicide resistance in other weed species, demanding stronger or different chemical solutions in the future. Furthermore, the long-term impact on soil health and beneficial microorganisms is a concern that warrants careful consideration and soil testing. Alternative methods, such as solarization (covering the area with clear plastic to bake the soil), present a more environmentally friendly approach. While effective in killing monkey grass and other vegetation underneath, solarization can also eliminate beneficial soil organisms, requiring soil amendment with compost or other organic matter to restore balance. The effectiveness of solarization depends on factors like climate and duration, and may require multiple applications or supplemental methods for complete control.And that's it!
