For more environmentally friendly controls, you can simply to pull up the clover. Be aware, though that the presence of the clover in the first place indicates that your soil is lacking in nitrogen. If you remove the clover, you should add nitrogen in the form of compost or granular fertilizer. If entire patches of lawn are bare once the clover is removed, you should reseed these areas with turf grass. To prevent the reappearance of clover, keep these spots healthy and well-fed.

There are two types of ragweed, but the form that haunts lawns is Ambrosia artemisiifolia, common ragweed.

Wild violets are probably the best of the bunch in terms of appearance amongst the common lawn weeds featured here. In fact, some homeowners find the flowers sufficiently pretty that they decide to just leave the plants alone. Indeed, this relative of the Johnny-jump-up isn’t far inferior to Johnny in the looks department—and you won’t have to buy it. Violets may actually work very well if you want a naturalistic feel to your lawn.

Even your most powerful herbicide is no longer useful once the plant begins to bloom.

Wild violet also spreads by rhizomes under the ground. People who battle this weed will tell you it mostly ends up in places it is not welcome. Worse yet, wild violet is quite resilient. Amazingly, it adapts to mowing by growing shorter so it can dodge the blade and give itself ample time to develop seeds.

Let’s take them one at a time so you can identify the purple flower weed in your lawn or garden, but first a word about eliminating these weeds.

Where does it grow?

The square-shaped stem has a lower and upper section. The lower section is entirely devoid of foliage, yet the upper part bears purplish colored leaves with triangular tips. These leaves have petioles, or stems, that connect them to the main stem.

Purple Deadnettle prefers a quite unsavory habitat. It can thrive in moist areas such as drainage ditches, fallow fields, waste areas, and weedy edges of woodlands.

This perennial bloomer has deep green heart-shaped leaves and delicate stems. These stems support a rather pretty purple flower, of course.

What is it?

Organic methods to eliminate this weed are pretty standard. You can control small patches with hand pulling Henbit. Just be careful to control inadvertent seeding by carefully pulling the plants and putting them in a bucket or sack. Do not leave them on the ground.

Selfheal can be removed by hand, using a grubber or small knife, taking care to remove all of the root.

Recommended chemicals for the control of selfheal
2,4-D + Mecoprop-p
2,4-D + Dicamba
2,4-D + Dichlorprop-p
Mecoprop-p + Dicamba
Clopyralid + Fluroxypyr

General information
Selfheal grows on a wide variety of sites including grasslands, meadows, woodland, roadside, lawns and fine turf.

As well as medicinal uses, selfheal is also edible, the leaves can be used in a salad, or added into a soup or stew. The leaves can also be boiled to make a nourishing herbal tea.

Identification

Selfheal is not a difficult weed to control using a selective herbicide and a single treatment is usually effective. The most suitable time for treating weeds in turf and lawns is during periods of strong growth, usually during late spring and early summer.

Mow the lawn on a regular basis to prevent the seed heads from forming.

On the chemical side of things, spot treating individual plants can prove very effective. If the infestation has been allowed to become more widespread, then the whole area may need to be treated, using a suitable selective weedkiller. If possible only treat the area infected by weeds to keep chemical use down to a minimum.
