Spurge is a pesky weed that can quickly disrupt the uniformity and beauty of your lush green lawn. Known for its sprawling growth and ability to thrive in tough conditions, spurge competes with your grass for valuable sunlight, water, and nutrients. Worse, some species of spurge, like spotted spurge, release a milky sap that can irritate the skin. If left unchecked, spurge can take over large areas of your lawn, making it vital to act promptly and effectively.
This guide provides actionable information on hHow to Get Rid of Spurge in Lawn and prevent spurge infestations in your lawn. Whether you prefer organic solutions, chemical treatments, or preventive measures, you’ll find the techniques necessary to restore your lawn’s health and vitality.

What Is Spurge?
Spurge refers to a group of weeds belonging to the Euphorbia genus. These weeds are most notorious for their resilience and fast-spreading nature, making them a common issue for homeowners.
Characteristics of Spurge:
- Leaves:
Spurge leaves are small, oval-shaped, and often feature a red or purplish spot in the center (common in spotted spurge). - Growth Habit:
It grows flat against the soil in a radial pattern, which allows it to spread easily and resist mowing. - Roots:
Spurge roots are shallow, making it easy to pull, but the weed grows back rapidly if not removed correctly. - Sap:
Many spurge species excrete a white, milky latex sap when cut or damaged. This sap can irritate the skin and is mildly toxic if ingested. - Seeds:
A single spurge plant can produce thousands of seeds, which remain viable in the soil for several years.
Locations Where Spurge Thrives:
- Lawns with thin or patchy grass cover.
- Compacted, dry, or nutrient-poor soils.
- Areas with excessive sunlight and minimal shade.
Identifying spurge early is key to controlling its spread before it becomes an overwhelming problem.
What Causes Spurge in Lawns?
Spurge thrives in conditions where lawns are weak or poorly maintained. Below are some of the most common factors that encourage spurge growth:
Cause | How It Encourages Spurge | Solution |
---|---|---|
Compacted Soil | Weakens grass, leaving gaps for spurge to grow. | Aerate soil annually to improve grass growth. |
Underwatered Lawn | Stressed grass allows weed seeds to establish. | Deeply water your lawn, especially in summer. |
Thinning Grass | Bare spots enable spurge to germinate easily. | Overseed and fertilize to maintain lawn density. |
Excessive Sunlight | Spurge grows best in full sun settings. | Maintain taller grass to shade the soil. |
Lack of Maintenance | Areas left untreated act as breeding grounds for weeds. | Mow, fertilize, and dethatch regularly. |
By addressing these underlying causes, you create an environment less hospitable for spurges.
How to Get Rid of Spurge in Lawn
Eliminating spurge requires a thorough approach that combines manual removal, lawn care improvements, and possibly chemical treatments for large infestations. Below are the best practices for tackling spurge effectively.
1. Hand-Pulling Spurge
For small infestations, manual removal is a safe and effective way to deal with spurge.
Steps for Manual Removal:
- Water the Lawn:
Ensure the soil is moist; this makes it easier to pull roots out completely. - Wear Gloves:
Protect your skin from the sap, which can cause irritation. - Pull from the Base:
Remove the entire plant, including roots, to prevent regrowth. - Dispose Securely:
Place removed weeds in a trash bag to avoid spreading seeds.
Pros:
- Eco-friendly and chemical-free.
- Immediate removal of visible weeds.
Cons:
- Time-consuming and labor-intensive for larger infestations.
- Missing any roots or seeds can lead to regrowth.
2. Organic Solutions for Spurge
Environmentally friendly methods can be effective for controlling spurge in lawns.
Natural Remedies:
- Corn Gluten Meal:
A natural pre-emergent herbicide that prevents spurge seeds from germinating. Apply in early spring for best results. - Vinegar Spray:
Spraying horticultural vinegar (20% acetic acid) directly onto spurge works as a post-emergent control method. Be cautious, as it can harm surrounding grass. - Boiling Water:
Spot-treat individual plants by pouring boiling water over them. This kills the weed on contact but is non-selective.
Pros:
- Safer for kids, pets, and beneficial insects.
- Aligns with sustainable lawn care principles.
Cons:
- May require multiple applications to achieve desired results.
- May damage grass and other nearby plants if not applied carefully.
3. Chemical Herbicides
When spurge infestations become too extensive for manual or organic methods, chemical solutions might be necessary.
Types of Herbicides:
- Pre-Emergent Herbicides:
Stop spurge seeds from germinating. Use products labeled for spurge control in early spring. - Post-Emergent Herbicides:
Kill actively growing spurge plants without damaging your lawn. Look for selective herbicides containing dicamba or 2,4-D.
Tips for Application:
- Apply herbicides during dry weather when spurge is actively growing.
- Follow all label instructions for dosage and safety.
- Avoid overapplication, which can weaken your lawn and harm the environment.
Pros:
- Fast and highly effective for widespread infestations.
- Selective herbicides target spurge while preserving your grass.
Cons:
- Requires proper handling to prevent environmental damage.
- Costlier than manual or organic methods.
4. Strengthen Your Lawn
A healthy, well-maintained lawn is the best defense against spurge and other weeds.
Lawn Care Tips:
- Aerate Regularly:
Loosen compacted soil to allow grass roots to grow deeper. - Overseed Bare Spots:
Fill in thin areas with thick, fast-growing grass varieties to crowd out spurge. - Mow Strategically:
Keep your grass at a height of 2.5–4 inches to shade the soil and block out sunlight, which spurge needs to grow. - Fertilize Wisely:
Use a balanced, slow-release fertilizer to strengthen your grass and improve its ability to compete with weeds.
By prioritizing lawn care, you build an environment where spurge struggles to survive.
When to Treat Spurge
The effectiveness of your spurge control strategy depends heavily on timing. Targeting the weed at the right stage of its life cycle yields the best results.
- Spring:
Apply pre-emergent herbicide to stop seeds from sprouting. - Summer:
Remove actively growing spurge manually or with post-emergent herbicide before it produces seeds. - Fall:
Address any lingering weeds and strengthen your grass to outcompete spurge in the upcoming season.
Monitoring your lawn throughout the year ensures quicker action and better outcomes.
Preventing Spurge From Returning
Once you’ve eliminated spurge, focus on long-term prevention to keep it from returning. Here’s how to safeguard your lawn against future infestations:
- Maintain Dense Grass:
A thick, well-established lawn leaves no room for spurge to grow. - Water Deeply and Less Frequently:
Shallow, frequent watering encourages weed growth. Water deeply to promote resilient grass. - Apply Pre-Emergents Annually:
Use a pre-emergent herbicide each spring to prevent spurge and other weeds from sprouting. - Monitor Regularly:
Inspect your lawn frequently to catch and remove spurge early. - Improve Soil Quality:
Use compost or organic soil amendments to enrich the soil and deter weeds.
Consistency is key to ensuring your lawn stays spurge-free.
Real-Life Case Studies
Case Study 1:
A homeowner in Arizona dealt with a spotted spurge infestation on their 1,200 sq. ft. lawn. By applying vinegar during the summer and overseeding in the fall, they eliminated the weed within one season.
Case Study 2:
A Texas family riddled with spurge used a selective herbicide in June and fertilized their yard with nitrogen-rich fertilizer. This doubled their grass density and reduced spurge coverage by 90%.
These success stories illustrate how a combination of techniques can achieve lasting results.
FAQs About Spurge
1. Does pulling spurge work?
Yes, but the entire root system must be pulled to prevent regrowth.
2. What is the best pre-emergent for spurge?
Corn gluten meal or herbicides containing oryzalin can effectively prevent spurge seeds from sprouting.
3. Can spurge harm pets?
The sap from spurge can cause mild irritation in pets if ingested or if it comes into contact with their skin.
4. Does spurge grow back after mowing?
Yes. Mowing only removes the top growth, leaving the roots intact and allowing it to regrow.
5. What grass types resist spurge?
Thick varieties like Bermuda or St. Augustine grass can crowd out spurge naturally.
