Spotted Spurge: A Common Weed and How to Control It
Spotted spurge is a pesky weed that can quickly invade your lawn or garden, making it look unsightly and unkempt. It’s important to know how to identify and control spotted spurge to keep your outdoor spaces looking their best.
Identifying Spotted Spurge
Spotted spurge is a dark green plant with reddish stems that grows low to the ground in a mat-like fashion. Its leaves are oval-shaped with a distinctive red spot in the center, which is why it’s called spotted spurge. The plant also has small, pink flowers and a milky white sap that can irritate the skin.
Problems Caused by Spotted Spurge
Spotted spurge can be a nuisance in your yard because it can:
- Compete with your desired plants for water, nutrients, and sunlight
- Spread rapidly through its seeds and tap root
- Make your lawn or garden look untidy
- Cause skin irritation due to its milky sap
How to Control Spotted Spurge
Controlling spotted spurge can be challenging, but it’s not impossible. Here are some effective methods:
Hand Pulling
Hand pulling is a simple and effective way to remove spotted spurge, especially if the infestation is small. Be sure to wear gloves to avoid skin irritation from the sap. Pull the entire plant, including the tap root, to prevent regrowth.
Mulching
Mulching around spotted spurge can help smother the plant and prevent it from receiving sunlight. Use several layers of newspaper or several inches of wood mulch to cover the ground.
Herbicides
Herbicides can be used to kill spotted spurge, but they should be used as a last resort. Many herbicides only work on young spotted spurge plants, so it’s important to apply them early in the growing season. Non-selective herbicides can kill mature spotted spurge, but they will also kill any other plants they come into contact with.
Pre-Emergent Sprays or Granules
Pre-emergent sprays or granules can be applied before spotted spurge seeds germinate to prevent them from sprouting. These products are most effective when applied in early spring.
Solarization
Solarization involves covering the infested area with a clear plastic tarp during the hottest part of the summer. The heat from the sun will kill the spotted spurge and its seeds. However, this method will also kill any other plants or organisms in the soil.
Preventing Spotted Spurge
The best way to control spotted spurge is to prevent it from taking hold in your yard in the first place. Here are a few tips:
- Keep your lawn or garden well-maintained by mowing and watering regularly
- Remove weeds promptly to prevent them from spreading
- Improve the soil quality by adding compost or manure
- Avoid overwatering, as spotted spurge thrives in moist soil
Additional Tips
- If you’re having trouble controlling spotted spurge, consult with a local nursery or gardening expert for advice.
- Be patient and persistent in your efforts to control spotted spurge. It may take some time and multiple treatments to completely eliminate it.
- Remember that organic methods of spotted spurge control are generally safer and more environmentally friendly than chemical herbicides.
