Dandelions, Clover and Creeping Charlie: Weed Control for North Shore Lawns
How to identify and control the broadleaf weeds that take over North Shore lawns, and why fall treatment beats spring for most of them.
Every North Shore lawn fights the same short list of broadleaf weeds. Knowing which one you have matters, because the plants behave differently and the thing that beats one is useless against another.
Creeping charlie, the hard one
Also called ground ivy, this is the scalloped leaf, square stemmed creeper with small purple flowers in spring, and it is the weed we get the most calls about. It spreads by above ground runners that root at every node, so every fragment you leave behind when you pull it becomes a new plant. Hand pulling a large patch reliably makes it worse.
Creeping charlie also loves shade and damp soil, which is why it colonizes the north side of houses and the ground under mature trees. Improving drainage and thinning tree canopy to let light in removes the conditions it depends on. For control, it needs a broadleaf herbicide containing triclopyr, applied in fall, and honestly it usually takes two autumns to fully clear a bad infestation.
Dandelions
The familiar one. Dandelions have a deep taproot, so snapping off the top does nothing. If you dig, you need the full root. A broadleaf herbicide works well on them, and fall applications outperform spring because the plant is actively moving energy down into that taproot and carries the product with it.
Clover
White clover is worth pausing on, because it is not really a problem plant. It fixes its own nitrogen, stays green in drought, and some homeowners now deliberately seed it. If you do not want it, the useful insight is that clover thrives where nitrogen is low. A lawn on a proper feeding schedule tends to outcompete it without any herbicide at all.

In spring, perennial weeds push energy upward into leaves and flowers. In fall they reverse, pulling sugars down into roots and crowns to survive winter. A systemic herbicide applied in that autumn window gets carried straight down to the root with everything else, which is why September and October treatments are dramatically more effective than April ones on the same weed.
- Treat on a calm day between roughly 60 and 80 degrees so the product works and does not drift.
- Do not mow for a couple of days before or after, so there is leaf surface to absorb the spray.
- Spot treat rather than blanket spraying whenever the weeds are scattered.
- Keep herbicide off garden beds, and remember many broadleaf products damage trees and shrubs through the root zone.
The part that actually matters
Weeds are a symptom. They establish where turf is thin, soil is compacted, the lawn is cut too short, or shade and moisture favor them. Chemistry buys you a season. Fixing density, mowing height, and soil is what keeps them out for good.
If your lawn is more weeds than grass at this point, it usually needs a plan rather than a product. Call or text 224-634-0673 or 224-200-8363 and we will walk it with you.
Frequently asked questions
- How do I get rid of creeping charlie in my lawn?
- Use a broadleaf herbicide containing triclopyr, applied in fall between mid September and early November. Hand pulling spreads it, because every rooted runner fragment regrows. Severe infestations typically need treatment in two consecutive autumns.
- When is the best time to kill lawn weeds in Illinois?
- Fall, from mid September through early November. Perennial weeds move stored energy down into their roots in autumn and carry systemic herbicide with it, making fall treatments far more effective than spring ones.
- Why does my lawn have so much clover?
- Clover fixes its own nitrogen, so it outcompetes grass in lawns with low soil nitrogen. It is usually a sign the lawn is underfed rather than a disease. A consistent fertilization program will thin clover out naturally.
- Will weed killer hurt my trees and shrubs?
- It can. Many broadleaf herbicides are absorbed through roots, and tree and shrub roots extend well past the drip line into the lawn. Keep applications off bed edges, avoid spraying on windy days, and never apply under stressed or newly planted trees.
