For Creeping Charlie in lawns, choose a selective herbicide with triclopyr to save the grass; for beds or hardscapes, choose non-selective glyphosate.
Creeping Charlie (ground ivy) spreads fast and smothers lawns if you reach for the wrong jug. The difference between selective and non-selective herbicides determines whether your grass lives or dies—and the active ingredient you pick decides whether the Creeping Charlie actually dies at all. Here’s what separates the two, which one works where, and the timing that makes either choice pay off.
What’s the difference between selective and non-selective herbicides?
A selective herbicide targets specific broadleaf weeds while leaving grass and turf untouched. Non-selective herbicides kill every green thing they touch—grass, weeds, shrubs, everything. That distinction dictates where each belongs.
For lawns and turf where you want the grass to stay, selective herbicides are the only option. For driveways, patios, fence lines, or garden beds you plan to replant, non-selective products get the job done faster. The table below lays out the full comparison.
| Feature | Selective Herbicide | Non-Selective Herbicide |
|---|---|---|
| Target | Broadleaf weeds like Creeping Charlie, dandelions, clover | All vegetation (grass, broadleafs, woody plants) |
| Best location | Lawns, turf, ornamental beds where grass is desired | Driveways, sidewalks, fence lines, garden beds for replanting |
| Key active ingredients | Triclopyr (most effective), Dicamba, 2,4-D (needs combination), MCPP | Glyphosate (Roundup and similar) |
| Recommended products | Speedzone, Trimec, T-Zone SE (contains triclopyr, 2,4-D, dicamba) | Roundup (various formulas) |
| Effect on grass | Safe for most lawn grasses when used per label | Kills grass on contact |
| Residual effect | Low; grass can be seeded within weeks | Some formulas prevent replanting for weeks to a year |
| Tree root zone safety | Do not spray over tree root zones; trees absorb chemicals | Same risk—keep away from root zones |
Which active ingredient actually kills Creeping Charlie?
Triclopyr is the single most effective ingredient for Creeping Charlie. University of Minnesota Extension confirms that 2,4-D alone fails against this weed—it needs triclopyr or dicamba alongside it to work.
Three-way combinations (2,4-D, MCPP, and Dicamba) are effective broadleaf options, but standalone triclopyr products often outperform them because the active-ingredient concentration is higher. If your go-to broadleaf spray doesn’t contain triclopyr, it probably won’t stop Creeping Charlie.
There’s also a non-synthetic third option: iron chelates (iron HEDTA). Chelated iron products have fewer environmental side effects and handle tough weeds, though results vary more than synthetic herbicides. Grounded and Growing notes it as a viable middle ground for readers who want to minimize synthetic chemicals.

When should you apply each type?
Late fall is the single best window for either herbicide type. Apply the first dose between late September and early November, when Creeping Charlie is actively growing and storing energy in its roots for winter. That root uptake carries the chemical deep where it does the most damage.
A second application 3 to 4 weeks later is mandatory—one pass never finishes the job. Iowa State University Extension recommends two spaced treatments for reliable control. Spring application works but delivers weaker results because the plant isn’t pulling energy downward the same way.
Apply when the weeds are in bloom or just past bloom for best uptake. Always follow the bottle label’s rate and safety instructions.
Common mistakes that waste your time
- Using 2,4-D alone. It won’t kill Creeping Charlie. Pair it with triclopyr or dicamba.
- Spraying only once. A single application knocks back the leaves but leaves the roots untouched. The second pass 3–4 weeks later finishes them.
- Applying in spring only. Spring hits the leaves but misses the root-storage window. Fall treatments get better uptake.
- Spraying over tree root zones. Tree roots absorb selective herbicides too, causing leaf curl and long-term damage. Keep sprays inside the lawn area, away from the drip line.
- Using Borax or homemade mixes. Boron builds up in soil and damages it for years. Results are inconsistent, and the soil harm outlasts the weed.
- Spraying non-selective herbicides on windy days. Drift kills desirable plants. Use a sponge or wipe applicator for spot treatment, or shield plants with buckets or plastic sheets.
How to apply safely around trees and gardens
Selective herbicides are safe for grass, but they can still damage trees when applied over root zones. Northern Gardener warns that tree roots extend well beyond the canopy dripline, and herbicide uptake through those roots causes injury that shows up months later. Keep all sprays confined to the lawn area; if Creeping Charlie has invaded a garden bed, hand-pull it or use a sponge application of non-selective herbicide to avoid drift.
For small infestations, physical removal works—but you must extract every piece of root and stem. Any fragment left behind regrows. Follow up by maintaining dense, healthy turf. Mowing taller shades the soil surface and discourages Creeping Charlie from re-establishing. Aerating and dethatching also help because the weed thrives in the thick thatch layer.
| Application Factor | Best Practice |
|---|---|
| Season | Late fall (late September – early November) |
| Number of treatments | Two, spaced 3–4 weeks apart |
| Weed state | Actively growing and in bloom |
| Method for small patches | Spot spray or sponge/wipe application |
| Protection for nearby plants | Buckets, boxes, or plastic sheets as barriers |
| Aftercare | Maintain tall mowing height, aerate, dethatch |
Your quick decision guide
Walk the yard and check where the Creeping Charlie is growing. If it’s mixed into lawn grass, buy a selective herbicide with triclopyr listed on the label—Speedzone, T-Zone SE, or Trimec are reliable picks. Apply in late fall, come back 3–4 weeks later for round two, and keep the mower deck high to shade out future invaders.
If the Creeping Charlie is in a driveway crack, a garden bed you’re clearing, or along a fence line where nothing green is meant to grow, reach for a non-selective glyphosate product. Use a sponge or wick applicator to keep the chemical off nearby plants, and expect to wait before replanting—check the label for how long.
FAQs
Can I use the same sprayer for selective and non-selective herbicides?
Not without thorough cleaning. Even trace amounts of non-selective glyphosate left in a tank or hose will damage grass the next time you spray a selective product. Rinse the tank, lines, and nozzle three times with water, or dedicate a separate sprayer for each type.
Will selective herbicide kill Creeping Charlie in flower beds?
No—selective herbicides are designed to spare grass, not flowers or ornamentals. They will damage or kill most garden plants. For flower beds, hand-pull the Creeping Charlie or use a non-selective product applied carefully with a sponge to avoid contact with desired plants.
How long after spraying can I reseed the lawn?
It depends on the product. Most selective herbicides recommend waiting 2 to 4 weeks before overseeding. Non-selective glyphosate formulas vary widely—some allow seeding after a few days, while others with residual additives require waiting months or up to a year. Always check the specific label on your bottle.
Does vinegar or dish soap kill Creeping Charlie?
Household vinegar (5% acetic acid) burns the leaves but does not reach the roots, so the weed regrows within weeks. Horticultural vinegar (20% or higher) works better but is caustic and still inconsistent. Dish soap has no measurable effect on its own. Neither matches the reliability of triclopyr-based products.
Is it safe to compost Creeping Charlie after pulling it?
Only if your compost pile reaches temperatures hot enough to kill seeds and root fragments—typically 130–140°F for several days. Most home compost piles do not sustain that heat, and Creeping Charlie roots regrow from tiny fragments. Bag and discard pulled plants with yard waste instead.
