A rather innocuous plant, common plantain can simply be mowed whenever you mow the lawn. Its relative, Plantago lanceolata is a similar weed, but with narrow leaves. Now a ubiquitous lawn weed in North America, broadleaf or "common" plantain was brought to the New World by colonists from Europe for its medicinal uses. Common plantain has many medicinal uses. Mashed, it can be used as a poultice for bee stings; the leaves can also be dried and made into a tea to treat diarrhea.

Once you've identified nuisance plants, you can more readily access information on eradication. In some cases, however, finding out more about the plants in question may persuade you to show more tolerance toward them. There are even some edible weeds. Some are worth your time to remove while others don't cause much harm (and may even have beneficial aspects).

Repeat the treatment several times during the growing season. Eco-Lawn may need four to eight applications before the nutsedge dies off completely.
Dandelions are the bane of many peoples lawns. Thriving in thin, sparse turf, dandelion seeds float through the air looking for the slightest opening in the lawn to propagate. Meanwhile, below ground, they develop a taproot up to 10″ long. This taproot is thick but brittle and easily fractures and any piece of the taproot that remains in the ground will re-grow.
White Clover also known as Dutch Clover is a cool-season perennial that is native to Europe and Asia. Low growing, it forms creeping stems (stolons) that produce roots and shoots along its stem. Being in the legume family, it fixes nitrogen into the soil which enables it to thrive in unfertilized areas.
Allow your lawn to grow for a few days prior to application. Herbicides works best when the nutsedge is growing vigorously and may not be as effective if applied immediately after cutting it down. Wait two or more days after your last lawn mowing before applying the chemical to the lawn.
Non-organic Solution: Often, by the time Crabgrass is noticeable it is too late to treat, however there are chemical crabgrass treatments. Contact your local garden centre or hardware store for options in your area.
Vigilance and persistence are required to control Bindweed, where you see it, cut it off at the soil level. Don’t try to pull it out as it will just re-sprout from its roots. By continually cutting it off at ground level as often as you can, will prevent the Bindweed from experiencing photosynthesis and thus it will eventually starve to death. Another alternative is to pour boiling water on Bindweed as boiling water kills all plants. If you use boiling water you will need to re-seed the affected areas.
Native to Europe, Quackgrass is easy to identify. It produces long, wide-leafed grass and the grass blades have a rough almost burr-like feel to them. The thick, white roots form deep, dense mats and these roots tend to break easily when pulled leaving pieces in the soil after the grass has been removed. Any pieces left in the ground will quickly re-grow into new plants.
Canada thistle brings a thorny problem to any landscape where it appears. This prickly beast grows from seed that can blow into your yard, or it can sprout from root pieces, which sneak in with bulk topsoil or mulch loads. Size varies, with many mature plants reaching 5 to 8 feet tall. In a single season, one plant can produce a 20-foot-long root system, and it only takes one piece of root to produce a plant. Control through weeding, but dig carefully and deeply to get the horizontal root. After digging, if another sprout appears, pull it, too. Or use an herbicide. The best time to spray is as soon as leaves break ground. Spray repeatedly through the growing season, and you will eventually kill it.
When it comes to violets, opinions are divided. To some, it’s a weed of the vilest kind; to others, it’s a dainty wildflower. No matter which camp you support, it’s vital to know that while violets have a literary reputation of being shy, in the landscape, they are anything but that. This perennial bloomer boasts a prolific personality, spreading easily by underground stems and seeds. In the lawn, it adapts quickly to lowered mower heights, growing shorter as needed to dodge the blade. Violets thrive in moist, shady sites, but mature plants are drought tolerant. The solution to eliminating violets? Vigilant hand-weeding (be sure to remove all the rhizome) and targeted herbicide use.
Also known as wild morning glory, bindweed is bad news. Hedge bindweed spreads by seed and creeping underground stems; field bindweed spreads by weeds and roots, which grow up to 30 feet deep. These plants open flowers that look like morning glory, which is why many gardeners let them grow. They’ll grow along the ground like a ground cover, but if there’s a support nearby, like a rose, fence or tree, the vines twine and climb. Since these plants are tough to eradicate, it’s important not to let any get a foothold in your yard. Pull them as soon as you see them, and continue pulling each time they emerge. It will take possibly years for the roots to exhaust, but you can eventually beat them this way. For quicker kill, apply an herbicide that kills the root. It may still take more than one treatment, but you will kill these persistent plants.
A non-native, invasive plant, garlic mustard grows in sun or shade, dry soil or wet. Its roots produce a chemical that inhibits other plants from growing. Thanks to these adaptations, it quickly colonizes areas. In many regions it’s displacing native forest plants, and in backyard gardens, it can quickly take over planting beds. Garlic mustard is a biennial, producing a small rosette of toothed, kidney shape leaves in Year 1, followed by a tall stem topped with flowers in Year 2. Remove (pull up stems and roots) and destroy any garlic mustard that appears on your property, putting it out with the trash.

Native Americans called broadleaf plantain “white man’s foot,” because it seemed to appear everywhere white settlers went. Touted as a healthy backyard weed with various benefits, broadleaf plantain can create a small colony that resembles a ground cover if grass is thin and soil is dry and compacted. Hand pulling this weed is an effective solution, especially with small infestations. Plants have a fibrous root system and come up easily with a Three-Claw Garden Weeder. Or spray plants with an herbicide any time they are actively growing.
These perennial weeds smell like their namesakes, and there’s no mistaking their presence when you mow over them. Wild onion has flat leaves, while garlic is round. They both grow from bulbs and form clusters similar to chives. To remove them, avoiding hand-pulling. It only serves to separate the main bulb from the tiny bulblets surrounding it, which remain in soil and sprout. To dig wild onion or garlic, excavate about 6 inches deep to get the whole bulb. Otherwise, spray with herbicide. The kind that kills nutsedge works on wild onion and garlic. In late spring, these weeds produce small bulbs atop long stems. Snip these and destroy them. They contain new bulbs—they’re this weed’s way of spreading and covering new ground.
