Red weed growing in lawn

Wild violets are probably the best of the bunch in terms of appearance amongst the common lawn weeds featured here. In fact, some homeowners find the flowers sufficiently pretty that they decide to just leave the plants alone. Indeed, this relative of the Johnny-jump-up isn’t far inferior to Johnny in the looks department—and you won’t have to buy it. Violets may actually work very well if you want a naturalistic feel to your lawn.

Yellow Dock (Rumex crispus)

There are many species of clover, all of which homeowners would like to banish from the lawn. This is perhaps a mistake, as clovers are actually quite healthy for a lawn. It is fragrant, resists most pests, helps to aerate the soil, and best of all, as a member of the pea family, clover actually adds nitrogen to the soil. There is a lot to be said for a lawn that contains a healthy percentage of clover within its turf-grass blend. Besides red clover (Trifolium pratense), white clover (Trifolium repens) is the most common lawn clover.

If you choose to engage the enemy organically (by digging it up), you will have to be persistent, too. The tiniest pieces of vegetation in the soil will regenerate.

Wild Violets (Viola spp)

Yellow or "curly" dock is one of the easier plants listed here to identify. It has a distinctive dried flower head that resembles coffee grounds. A dock is a tall plant when mature, so you may not associate it with lawns, but seeds may well sprout up as tiny plants in your lawn, and especially along fence lines if you haven't trimmed diligently.

Common plantain (Plantago major) may take you back to your childhood. Did you have a pet bunny as a kid? What did you feed it? If you built a bottomless outdoor cage for your pet (with the cage resting directly on the ground, without legs), your bunny no doubt would eat the vegetation under him. Grass would have been on the menu, but another favorite dish would have been common plantain (if present). Common plantain is also edible by people and may be used in salads or as a cooked green.

Non-organic Solution: Chemical controls will require repeated applications to totally eradicate Cinquefoil. Contact your local garden centre or hardware store for options in your area.

Non-organic Solution: A broadleafed weed killer that contains a combination of 2-4-D, dicamba and MCPP/MCPA will be effective. Contact your local garden centre or hardware store for options in your area.

Black Medic also called Yellow Trefoil is an annual species so it only lives one year but it makes a lot of seeds that can remain viable for several years. It’s seeds germinate in the spring and are capable of establishing in drought-prone or disturbed soils. Black medic is a legume, meaning that it has the capabilities to fix its own nitrogen; thus, allowing it to out compete turf in nutrient-poor soils as well. These factors, in combination with its ability to tolerate low mowing heights, make black medic a common weed in lawns.

This method is most effective at the start of the growing season, when nutsedge is just barely beginning to germinate and sprout. Start by watering the lawn. You do not need to soak it, but the lawn should be evenly moist down to the soil.

Organic Solution:
The best way to effectively and permanently eradicate moss in the lawn is to physically remove the moss. Start by raking the area with a hard rake to loosen it. Then using the edge of a flat shovel, scrape away the moss and remove the debris. Next, top dress the area with compost and to seed it with Eco-Lawn seed. Eco-Lawn is far more shade tolerant than most turfs and will out-compete moss growth. If the affected area has heavy or compacted soil, it is a good idea to loosen the soil to a depth of at least 3 inches and re-grade to allow drainage before sowing Eco-Lawn. You can also make a spray consisting of 4 ounces of dish soap to one gallon of water and drench the moss with the solution. The moss will turn orange/brown in 24 hours and will dry up.

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.

Non-organic Solution: Spot spay in early spring or early fall with a non-selective herbicide containing glysophate (Round Up). As this also kills turf, you will need re-seed the areas you have sprayed.

Apply the herbicide during a dry period. Wait several days after your last watering and do not spray the herbicide if you may get rain four hours after application or if you expect heavy rains to follow in coming days. Water will wash the chemical away and it may not have the chance to do its job before that happens.

Non-organic Solution: Use herbicide before the nutsedge develops five true leaves. Leafy nutsedge has too many obstacles, preventing herbicides from sliding down to the “nuts” and the root. Herbicides work best early in the season, while nutsedge is still young and has minimal leaves.
