These Are The Weeds To Watch Out For In Summer
- June 21, 2021
Summer in Tennessee means warmer weather, bugs, and the age-old fight against weeds. From crabgrass to nutsedge, dozens of uninvited guests appear in our lawns and flower beds. At 4-EverGreen Lawn Care, our bed weed control aims to keep your weeds in check to reduce hand pulling and your extra time in your landscape.
This warm-season perennial prefers full sun and can affect both warm-season and cool-season grass. Look for blades of grass that are coarsely textured with hairs along the edge; it may even look like crabgrass. Many times, in fact, it is mistaken for crabgrass, but the tufts are rounder in comparison. This is a very stubborn weed.
One reason crabgrass is so annoying – aside from ruining the appearance of our lawns – is that it reproduces both via seeds and a root system. Other weeds can be eliminated quickly since they only produce seeds. With crabgrass, you may think you’ve done your job by digging out individual weeds, but that’s not the case. Unless you’ve thoroughly dug out the root system, you’ll need to rely on a reputable weed control product to eliminate this culprit. Like many seasonal weeds, crabgrass likes full sun. You may notice it germinates after you’ve mowed your lawn. That’s because the normal turfgrass is not able to overshadow it once the grass has been cut.
Nutsedge comes in two varieties and is named for the color of the flowers: yellow nutsedge and purple nutsedge. It does not often produce seeds but will spread through rhizomes and tubers. Like crabgrass, you won’t be rid of nutsedge by digging it out here and there. You need to target the root system for lasting results. Nutsedge looks like regular lawn grasses, but the shoots are stiffer than normal lawn grass, but they produce long skinny flowers, either purple or yellow. It responds well to the herbicide, so there’s no reason your lawn service technician can’t wipe it out. If nutsedge is a chronic problem in your lawn, consider installing weed mats or mulch to help discourage it from coming back. This is a very stubborn weed.
That mysterious, small purple flower that’s popping up in your lawn? It’s likely a wild violet, not a spillover from your garden. They’re increasingly becoming a problem for homeowners. And because they are short plants that grow close to the ground, you can rely on mowing your lawn to get rid of the problem. Also, they produce waxy, heart-shaped leaves. This waxy substance makes it harder for some herbicides to penetrate the leaves and eradicate the plant. This is a very stubborn weed.
Aside from causing horrific allergies in many people, ragweed also loves to ruin our gardens. It comes in two varieties: common ragweed and giant ragweed. Common ragweed has multiple leaflets with a fern-like appearance. These leaflets are roughly 6 inches long and 4 inches across. Another identifying feature on common ragweed appears on newly developed plant leaves, which usually have some purple speckling. Giant ragweed, on the other hand, has leaves that look like the palm of a hand. They can have three or five segments, and, as you may have guessed, giant ragweed tends to be quite tall – generally about a foot tall and 8 inches wide. Also, the leaves of giant ragweed are serrated, and the stems have small white hairs.
Also known as wood sorrel, oxalis often gets mistaken for clover. You can distinguish the two by looking at the edges of the leaves. Clover is much rounder, while oxalis has three heart-shaped leaves. It can also produce yellow flowers throughout the summer. Oxalis can also be much taller than clover – growing to be 4 to 12 inches tall. It does well in both full sun or shade. One adaptive trait that is good for oxalis, but annoying for homeowners, is how they spread their seeds. They produce capsules that explode when you brush against them, allowing the seed to disperse easily and thoroughly – not something you want in a lawn weed.
This summer annual is also known as silver crabgrass, which is surprising given that it is not a type of crabgrass. It is found in the lawn and landscape beds alike. You may also see it in areas where compacted soil is common. Goosegrass is a coarse, bunch-type grass that forms a rosette of low-growing flattened stems. The leaves are dark green, up to 12 inches long, and about 1/3 inch wide. You’ll find hairs near the base, and the blades can be either flat or slightly folded. In summer, you may notice the appearance of flowers with 2 to 10 spikes that look like a zipper. The stems can spread up to 2.5 feet long. This is a very stubborn weed.
