This plant is easy to control by hand-pulling.
Scientific Name: Tragopogon spp.
Description. This nonnative plant is not on noxious weed lists, but it spreads quickly and has recently been invading native wildflower meadows. We at RMBL remove it because it has become extremely dense, bordering on a monoculture, in some meadows. Salsify looks like a dandelion on steroids. The flower itself looks like a yellow daisy. The seed heads look like a big puffball, up to several inches in diameter. The numerous seeds float away in the wind, just like dandelion seeds. Plants can grow to be up to several feet tall.

Also called ground ivy, creeping Charlie thrives in poorly drained shady sites with fertile soil. Rounded leaves with toothed margins form along square stems that weave across the lawn. Blue funnel-shaped flowers appear from April to June. Controlling Creeping Charlie is difficult, especially in shady sites where there’s little competition from grass. Increase sunlight to these areas by pruning trees and shrubs. To control the spread by hand, dig out all the stems and roots or the plant will grow back. For large areas, apply a post-emergent broadleaf herbicide containing dicamba from mid-spring to early summer and in middle to late fall.
One of the most recognizable lawn weeds, dandelions have notched leaves and yellow flowers that become puffballs most of us blew on as kids. Their thick taproot sinks deeply into the soil, making it difficult to pull the entire plant out by hand. The weed often snaps, leaving the taproot in place to regrow, which isn’t a totally bad thing if you’re consistent with this method. Repeatedly removing the growth above ground makes it tough for the plant to produce food and the dandelion eventually will die. If you prefer a more immediate response, opt for a post-emergent herbicide designed for use in the lawn. All parts of the dandelion are edible, so you can toss them in a salad or sauté them as long as you haven’t exposed them to any herbicides.
A perennial weed, field bindweed is one of the lawn weeds that is tough and difficult to eradicate. It has arrowhead-shaped leaves and flowers resembling small morning glories. This vining weed spreads by underground rhizomes. It wraps around plants and spreads across lawns so densely that it can smother and kill them. Repeated pulling before the plant flowers and releases seeds is the best control method. Some post-emergent herbicides work, but be sure to read the label to confirm the product’s effectiveness against bindweed.
Just when you thought that your carpet of green grass couldn’t look any better, a weed pops through to remind you that you are not in control. Unfortunately, weed control is part of any lawn maintenance routine. Whether the seeds blow in on the wind, drop from a passing bird, or lie dormant in the soil waiting for the right time to emerge, it’s inevitable that they will find your grass. A quick response is key to preventing a few weeds from swallowing your entire lawn. Here are nine common lawn weeds and the best (and safest) ways to stop their spread.
• Never allow weeds to go to seed. A weed flower is a sure sign that the plant is preparing to set seed. Cut it down to prevent it from spreading.
