Spotlight on Spurge: That Sneaky Summer Invader

Written by Savanna Fiegl | 6/25/25 4:01 PM

If there were an award for "Most Persistent Lawn Nuisance," spurge would definitely be a finalist. This low-growing, fast-spreading weed shows up just in time to crash your summer lawn party—and it doesn't take no for an answer.

What is Spurge, Anyway?

Spurge (specifically prostrate spurge) is a warm-season annual weed that thrives in hot, dry conditions. It’s got reddish stems, small oval leaves, and usually forms dense, flat mats that creep along sidewalks, driveways, flower beds, and—unfortunately—your lawn.

You might even notice a milky white sap when the stem is broken. That’s latex, and while it's not toxic to most people, it can irritate the skin.

Why is Spurge a Problem?

Because it’s a survivalist. Spurge grows quickly from seed, spreads aggressively, and thrives in thin, compacted soil where your grass is struggling. Left unchecked, it can take over large areas, stealing moisture and nutrients from your turf and making your lawn look patchy and unkempt.

Spurge’s Favorite Haunts:

  • Thin or bare spots in your lawn

  • Edges of driveways, sidewalks, and patios

  • Hot, compacted areas with poor soil structure

  • Flower beds with sparse mulch coverage

How to Stop the Spread

1. Prevention Starts in Spring
Spurge seeds germinate when soil temps hit 60–65°F. Apply a pre-emergent herbicide in early spring to stop those seeds before they sprout.

2. Keep Your Lawn Thick and Healthy
A dense lawn is your best defense. Regular mowing, watering, and fertilizing helps turf outcompete weeds like spurge.

3. Mulch Your Beds Right
A 2–3 inch layer of mulch in flower beds helps block sunlight from reaching spurge seeds. Make sure it’s thick enough, but not suffocating.

4. Post-Emergent Herbicides
Already spotted spurge? Post-emergent weed control can knock it back.
