We told you about some common spring lawn weeds that spring up in our lawn grass in our articles 5 Common lawn weeds and 5 more common lawn weeds from our friends at lovetoknow.com. Here’s the final 3 from their list plus one more that’s a real bugger in the Fort Worth area. Hope you have none of these plants in your spring grass this spring! Also, be sure and read the article Grow a weed-free lawn.
While mushrooms and toadstools are fungi rather than weeds, they can still be unsightly plants and unwelcome guests on an otherwise pristine spring lawn. The plants grow rapidly in rich, moist soils, but most varieties of mushroom weeds will not harm the lawn. Plants can be picked and discarded, or killed through lawn mowing. If the problem spreads, fungicide treatments may be necessary.
2 Wood Sorrel
Wood sorrel are edible lawn weeds with a tangy taste. The plants are slightly toxic, however, and should not be consumed in large quantities. Also known as yellow oxalis, sheep sorrel, and yellow sour grass, these weeds respond well to herbicide treatments that can keep it under control.
3 Poison Ivy
In overgrown areas, poison ivy can become a spring lawn weed problem. These weeds are best known for the itchy rash it inflicts on individuals who brush against the plant, a reaction caused by the plant’s urushiol toxin. When working to remove poison ivy from your lawn and yard, always take proper precautions to avoid contact between the plant and bare skin. Avoid that spring urge to roll in the grass and weeds!
You can’t list spring lawn weeds without mentioning Crabgrass. Although lovetoknow.com doesn’t mention it, this rapid-spreading plant weed can cause an unsightly mess on any lawn. See garden-counselor-lawn-care for more pictures and description of crabgrass. These images show how the stolon puts roots down and branches up. Eventually it will put out a tall seed stalk. More seed stalks will shoot up from the center of the plant.
From Scotts website:
A Sprawling root
Crabgrass gets its name because it sprawls from a central root (stolon) low across the ground. It can become a problem quickly because it is able to grow vigorously in hot, dry conditions. Before dying in the fall, a single weed can distribute thousands of seeds which will be ready to germinate in spring.
More from Scotts on Crabgrass:
Set Mowing Height to High
Higher mowing encourages lawn grasses to shade and prevent the germination of crabgrass seeds. A deep, thick lawn seldom contains much crabgrass. You can discourage crabgrass by mowing at the proper height for your grass type.
Deep Water Your Lawn
Weeds are better adapted to adverse growing conditions than most lawn grasses. Shallow and infrequent watering will only weaken the roots of your grass, while allowing the crabgrass to thrive and take over. Water lawns deeply and less frequently. When you water, wet the soil to a depth of 4-6 inches. This usually requires the equivalent of 1/2-1 inch of rainfall.
