Common Weeds With Pink Flowers

Red Clover

These perennial weeds are a common sight in lawns, gardens, roadsides, parks, and meadows. They are also used as fodder for livestock animals. Red clover grows well in areas with bright sun and under-fertilized soil. It is also used as a medicinal plant in alternative systems of medicine.

Its taproots allow it to survive during drought stress. The root system also allows it to spread, making patches and clumps in new lawns that are not sufficiently fertilized. The weed is best controlled by selective herbicide containing dicamba and quinclorac. For best results, you should use the herbicides during the fall months.

Shining geranium is considered a noxious and invasive plant in many regions of the United States. It has escaped from gardens into wildlands and is regarded as a serious contaminant of nursery stocks, lawns, and gardens. It grows mixed with grasses, forbs, and moss in shady areas. These weeds have branching stems that are reddish in appearance.

The weed spreads by seeds that are forcefully ejected by seed pods or seed heads. To control the spreading of shiny geranium, you can uproot new plants. However, try removing their extensive root system as much as possible. Larger patches can be controlled by mulching or using chemical control methods.

Field bindweed is a long-lived perennial weed that forms a dense mat and has an extensive root system. The root system can reach depths of 20 to 30 feet and can give rise to new other plants. Weeds growing in optimal conditions can compete with the desirable plants and eventually compete them out.

Weed control in the case of field bindweed is not easy. The weed shows vigorous growth in fertile, rich soil, and its seed heads can stay dormant in the soil for up to 60 years. That is why weed control involves regular and constant vigilance.

Common Stork’s Bill

Common Stork’s Bill - weeds with pink flowers

The weed is named so because of the presence of seed pods that are shaped like Stork’s Bill. On maturation, the seed pods explode, sending the seed heads flying. These seed heads are feathery like dandelion seeds which helps them spread to great distances. Common stork’s bill is among the first plants germinating in late fall or spring.

If you see the above-ground growth of common stork’s bill, you should treat it with herbicides as soon as possible. The weed quickly advances through various growth stages and often escapes the herbicide application window. Also, only a few herbicides are usually effective against these lawn weeds.

Milk thistle is a prominent weed in disturbed areas such as roadsides, ditches, and fencerows. It can cause nitrate poisoning in cattle and other livestock animals. If not controlled, it can spread quickly, pushing out other plants in the area. It can form dense mats in heavily infested areas and produces 4 tons of weight per acre.

To control milk thistle plants in your lawn or garden, you can try uprooting them before the seed heads form. For heavily infested areas, foliar, broadleaf herbicides have proven the most effective. However, do not use non-selective herbicides as they can harm other plants in the area as well.

Frequently Asked Questions (FAQs)

What are the little pink flowers in my lawn?

If it is not a flower of a plant that you have planted yourself, chances are, it is a weed with pink flowers. Depending on the type of weed, these pink-flowering plants can ruin your beloved lawns and gardens. Therefore, it is better to get rid of them as soon as possible.

However, some of the pink-flowering weeds might also attract pollinators to the law and might be worth keeping around. Please read our guide above to find out about different pink-flowering weeds and whether or not they are worth keeping around.

What’s the difference between wildflowers and weeds?

From a bee’s perspective, they both are the same. However, as far as the human perspective is concerned, a wildflower grows in the wild, away from human settlements in its natural habitat, on its own. In contrast, a weed is a plant that is growing in the wrong place or where it is not supposed to grow.

However, these definitions are often relative, and one person’s wildflower can be another person’s weed.

How do you get rid of weeds with pink flowers?

It will all depend on the type of weed you are dealing with, the life stage at which you found the weed, and the severity of weed infestation. Sometimes, simple hand pulling might suffice, and other times, you might have to use chemical control methods to prevent weeds from taking over.
