Weeds with White Flowers (Common Lawn Weed Guide) 

Hairy-bittercress

There are many types of flowering weeds, some with white flowers, some with yellow flowers, and some with purple flowers. But lawn weeds are lawn weeds. If you’re hoping to grow a lush, weed-free lawn, you’ll want to be able to identify weeds with white flowers, which are particularly common lawn weeds. Here, we’ll explore how to identify and control weed types with white flowers like white clover, broadleaf weeds, perennial weeds, and more. 

White Clover

White-clover-in-lawn

White clover is a perennial weed that features spiky white flowers with a green-hued center with a reddish stripe that emerges in early summer. As a creeping plant, white clover can develop an extensive root system because it will develop roots where a stem node comes in contact with the ground. This root system can make it difficult to eradicate white clover from your lawn or garden beds. 

Gardeners can usually prevent white clover from running rampant in flower beds by mulching. As for lawns, a healthy lawn is your best defense against this invasive weed. White clover can be a particular nuisance for sparse, struggling lawns or unkempt garden beds.

How to Control White Clover

To get rid of white clover from lawn grasses, you can hand pull these lawn weeds or you can use an herbicide. However, because white clover can emerge from seed, you will likely need to combat it again in future seasons as the seeds can withstand high heat and may lay dormant. However, in time and with repeat seasonal applications and good routine lawn care (with fertilizer), you should be able to make your lawn less hospitable to these tenacious lawn weeds.

Chickweed

Chickweed

Common chickweed is an annual weed that features small daisy-like white flowers that bloom in spring. Chickweed prefers rich soil with lots of moisture and will tolerate shady areas well. If you have a chickweed problem, you might want to avoid overwatering your lawn while attempting to control this lawn weed. Moist soil is conducive to chickweed outbreaks.

How to Control Chickweed

Ideally, you should apply a pre-emergent herbicide in early spring to control chickweed. This will prevent seeds from germinating. Otherwise, you can use a broadleaf herbicide to get rid of chickweed. You can also hand pull these weeds as their roots are quite shallow. On the other hand, if any of the root material is left in the ground, you can expect chickweed to come back again. 

Hairy Bittercress

Hairy-bittercress

An annual weed, hairy bittercress emerges from winter, ready to sprout and spread seeds by early spring. This weed’s stems grow about nine inches tall from a basal rosette. It develops leaves with slightly scalloped edges and forms small tiny white flowers on its stem tops. The flowers turn into seed pods. Hairy bittercress thrives in the cool, rainy environment of early spring; before the hot summer weather arrives, this weed can spread aggressively. 

How to Control Hairy Bittercress

Hairy bittercress can be extremely challenging to eradicate. That’s because it spreads via seeds. Its long seed pod bursts to spread hundreds of seeds in multiple directions. Pulling hairy bittercress by hand is often fruitless labor; the weed has a long taproot. Unless you’re able to pull it out completely, the plant will return unperturbed and ‘eager’ to take over your yard. The best way to eradicate hairy bittercress from your lawn is to apply a post-emergent herbicide in the late spring or early fall. 

Daisy Weeds

Daisy weeds grow in all types of soils. These lawn weeds–you guessed it–look like common daisies. A common weed, these plants have telltale white petals and yellow centers. Some people enjoy seeing daisies (often thought of as wild flowers) growing in their grass with their cheerful white petals; however, like many common weeds, they will spread aggressively. These lawn weeds can spread by seed or their underground rhizomes, which makes them difficult to control. Lawn daisies typically bloom in late spring but can continue to bloom well into summer and even early fall.

How to Control Daisy Weeds

You can control this lawn weed using a tool called a daisy grubber. A daisy grubber is designed to pull out the daisy along with its shallow root system. If you don’t pull out all of the rhizomes, the plant will come back again. Chemical control using a weed killer may be more reliable for killing these weeds. Use a post-emergent herbicide to kill these grass weeds before they spread further.

Wild Carrot

Wild carrot, also commonly known as Queen Anne’s Lace, features delicate white flowers that resemble lace. When crushed, the plant smells like carrots. A biennial weed, wild carrot has a powerful taproot, but that’s only one of its means of propagation. A single flowering weed can produce as many as 40,000 seeds, making this weed a difficult one to eradicate from your grass.

How to Control Wild Carrot

If you decide to pull up wild carrot plants by hand, you should do so before it flowers. If it can’t flower, it can’t produce all of those seeds. Wild carrot is resistant to some herbicides so when choosing one, be sure that it can do the job. 

Dandelions

Dandelions with their familiar yellow flowers, long stems, and green leaves are among the most common lawn weeds. These weeds will happily pop up in your grass or your flower beds regardless of whether the soil is dry or fertile soil. Dandelions sport yellow flowers that turn to a white ball, which contains the seeds that can blow far and wide. This perennial weed has a taproot that can grow ten inches long. 

Yellow and white dandelion

How to Control Dandelions

You can control this common lawn weed by pulling them by hand before seed germination, but you must remove the root entirely, which is no easy task considering its length. Also, wear gloves because this weed has pointy leaves If you don’t remove the root system, the weed will return to invade your turf grass again and again. Many people prefer to apply a broadleaf herbicide or weed killer that is specifically formulated to kill weeds like dandelions. Weed control measures to kill dandelions often have to be repeated to effectively clear them from your grass.

Wild Violet

Wild violets are common perennial weeds found in grass that feature white or purple flowers. Like many other aggressive weeds with white or purple flowers, wild violets grow from rhizomes, so eradicating them means tackling their root system. These weeds can reproduce even without blooming, and their taproot ensures that they have plenty of water even during drought conditions. 

How to Control Wild Violet

Unless you enjoy this plant’s purple flowers in your grass, you’ll want to use an herbicide to kill these weeds. The ideal time for application is in the fall. It’s a good idea to use spot treat wild violet so that you don’t harm other plants.
