Easy Guide To Identifying Common Flowering Weeds

BLUE FLOWERING WEEDS

 

aquilegia vulgaris lawn weeds with flowers

aquilegia vulgaris prior to flowering

COLUMBINE AQUILEGIA Aquilegia vulgaris

 

Type: Perennial Broadleaf

Height: 30 – 80 cm (12-32in)

Flowering Time: June – July

 

What’s it like?

A colourful plant with long sparse stem. It has strong roots which can be difficult to pull out. The flowers have a nectar at the bottom of the long stem which bees and butterflies can access. The plants usually have blue flowers but there are other varities in shades of pink, purple, white and some almost black.

Why is it a problem for your lawn?

This weed will self-sows freely. A greedy plant that inhibits the growth of nearby plants. Attracts red spider mites to the garden which will then move on to any nearby crops such as strawberries, apples and pears. All or parts of this plant are poisonous.

Control

Dead head plants after flowering. The roots are very strong and can be difficult to remove entirely. Removing seedlings before they have a chance to spread or flower and set seed is obviously the ideal solution. However, if you are faced with a large spread of this weed you will need to use a chemical weed killer (herbicide) if using a spot weed killer you will need to treat each individual plant.

Flowering Germander speedwell lawn weeds

Germander speedwell lawn weeds before flowering

GERMANDER SPEEDWELL veronica chamaedrys

 

Type: Perennial Broadleaf

Height: 10 – 35 cm (4 – 14 in)

Flowering: Early May to late June

 

 

What’s it like?

A low growing bright blue-purple kidney shaped flowers with prominent veins in the middle. Flowers have a short life span, they open early morning full of nectar but the following day will wither and fall to the ground in the evening. Erect stem with hairy sides. Survives in all kinds of weather conditions. Originally grown as a rock plant until gardeners saw how invasive it became and became a troublesome lawn weed.

Why is it a problem for your lawn?

They root quickly even from small sections, which means they will quickly get out of hand in your lawn and garden borders. They produce numerous stems both creeping and rooting at the nodes. They spread forming a dense weed carpet on your lawn. Mowing your lawn will scatter the stem sections. If your lawn’s grass growth is weak it will allow the weed to spread quickly. If you add lawn clippings to your compost heap and then use the compost to spread around your garden, if the compost was not completely decomposed it will spread this weed around your garden. Even if you rake your lawn of lawn clippings, moss or weeds there will be many of the small rooted sections of this weed that will remain in your lawn.

Control

Like many weeds, Speedwell is much less likely to be a problem for your lawn if your lawn is healthy. By boosting your grass growth with a feed in the Spring or Summer months it will deter the spread of the weed. In Autumn a scarification, aeration together with a top dressing will benefit your lawn’s health. Speedwells are quite resistant to many of the lawn weed killers that are available to the general public. If you have a new lawn you must be very careful when applying weed killers as they will often cause damage if applied within 6 months of a newly sowed or turf layed lawn.

Flowering Campanula plant

full photo and close up photo of campanula leaf

CREEPING BELLFLOWER Campanula rapunculoides

 

Type: Perennial Broadleaf

Height: Aprox 30–80 cm (12–31 in)

Flowering: Early Summer through to Autumn

 

 

What’s it like?

Commonly found in lawns. Also known as Creeping Bellflower . Campanula has attractive blue flowers. The stem of this weed is erect with short hairy leaves. The basal leaves are narrow and triangular with a heart-shaped base with jagged edges approximately 12 centimetres (4 in) long. This plant has overwintering buds located just below the soil surface. It spreads by underground rhizomes which produce deep taproot shaped tubers, which are white and fleshy. Any part of the root can sprout into a new plant, making it extremely hard to get rid of.

Why is it a problem for your lawn?

Companula rapunculoides is a problem because it has dense and abundant roots and shoots. If there are any small roots that are left behind after weeding they will simply come back again within a couple of weeks and start to spread again throughout your garden. In a rich soil it can take over your garden beds and move into your lawns. In drier or heavier soils it will be more of a low maintenance plant.

Control

Creeping Bellflower is very difficult to eradicate. It is nearly impossible to control it by digging or pulling out the roots. Non-selective herbicides, such as glyphosate, can be effective, but it may require several applications to eliminate all the roots.

PINK / PURPLE FLOWERING WEEDS

 

Doves Foot Cranes Bill lawn weeds with purple flowers Doves foot Crane's bill (geranium molle) leaf

DOVES FOOT CRANEBILL Geranium molle

 

Type: Annual Broadleaf

Height: Up to 30 cm  (Up to 12 in)

Flowering: April to September

 

 

What’s it like?

Very common in UK lawn. Pinkish/Purple flowers 8 – 12 mm (1/2 inch) in diameter with jagged petals. Although found in many soil types, it prefers to grow in free draining soil, dry environment and a soil that is under-nourished. This weed has basal leaves that are round in shape, looking like a rosette, slightly hairy and consist of approximately 5 – 7 leaf points. The flowers are mainly pollinated by insects. This weed is generally found in lawns that have poor soil conditions and that are sparse in grass plants. A well cared for lawn should not have problems with this weed.

Why is it a problem for your lawn?

This weed is an invasive plant that thrives in poor soil conditions and can be difficult to remove with over the counter Weed killers. A widespread infestation will cause your lawn to be uneven.

Control

If your lawn only has a few of these weed plants, you may be successful with simple hand weeding. However, for a larger infestation, a selective herbicide will be necessary. Control with over the counter weed killers may prove to be difficult as it is resistant to most chemicals. Spot treat the area where the weeds are present. Repeat applications about 5 – 6 weeks later will be needed to effectively control this weed. This weed thrives in soil conditions with poor nutrient levels. To prevent this weed invading your lawn, a good lawn care programme that feeds and nourishes your lawn’s soil should be carried out. By maintaining your lawn you will help promote a dense sward which in turn will prevent weeds invading.

Self-heal lawn weeds with flowers

Leaves of Self-heal lawn weeds

SELFHEAL Prunella vulgaris

 

Type: Perennial Broadleaf

Height: 30cm (11 – 12 in)

Flowering: June to November

 

What’s it like?

Selfheal is a member of the mint family and very common weed found in all types of lawns and conditions throughout the UK. This weed spreads by creeping runners (rhizomes) which root at intervals. It thrives in closely mown areas of grass and in these conditions the leaves will have a purple tinge to them. The leaves are oval in shape and have slightly scalloped edges and can have either smooth or slightly hairy surfaces. Found in most lawns throughout the UK. Grown by creeping runners (rhizomes) The flowers are purple in colour and have a pair of leaves underneath them.

Why is it a problem for your lawn?

Selfheal loves grow in garden lawns, it is low covering and will survive close mowing. It will restrict the growth of your lawn’s grasses. Quite often if it establishes itself well into your lawn you will need to lift and replace the affected lawn turf.

Control

If you see only a few plants you should be able to remove by hand. A regular mowing will help to suppress the production of the seeds. Like most weeds, the infestation of Selfheal can be prevented by carrying out a good lawn care programme, which results in a strong healthy grass and root system. If your lawn has a widespread problem with Selfheal then a selective herbicide will need to be used. There are a variety of chemicals (herbicides) that will kill it. One application is usually enough, but apply another 6 weeks later if necessary.

SPEAR THISTLE

Spear Thistle lawn weeds with purple flower

(Cirsium vulgare)                              Spear thistle lawn weeds

Type: Biannual Broadleaf

Height: 30 cm – 1 m (1ft – 3 ft)

Flowering: July onwards

What’s it like?

A common and robust weed generally found on a waste ground or unmanaged grass lawns, where seeds are able to germinate and establish without too much competition. Once the plant has produced its seed it will then die. The roots of this weed form a branched taproot, which enables it to get strong anchorage into the ground.

The leaves of the Spear Thistle are dark green, prickly and hairy on the upper surface of the leaf. It’s flowering stems emerge from rosettes when the basal leaves get to about 20 – 40 cm in length. Stems will grow to 30 – 100cm in height. It will produce large purple flower heads from July onwards and will die back after producing seeds.

Why is it a problem for your lawn?

It easily regenerates from broken pieces. Individual plants can form large clumps and will anchor themselves well in the ground. They should be controlled if you wish to grow a good quality lawn since they compete for light, water and food with your grass plants.  They can also be unpleasant if stepped on.

Control

Mowing prior to flowering to reduce the number of seeds spreading. If you have small areas of Spear Thistle in your lawn you can remove by hand hoeing by removing the growing point and tap root.
Persistent and larger areas of this weed will need an application of selective broadleaf herbicide when the plant growth is active. The best time to apply weed killer is when the plant is growing vigorously before flowering.  Several applications may be necessary to fully kill this invasive weed.

WHITE FLOWERING WEEDS

 

Flower of white clover law weeds leaf of white clover lawn weeds

WHITE CLOVER Trifolium repens

 

Type: Perennial Broadleaf

Height: Up to 18 cm (7in)

Flowers: June to September

 

 

What’s it like?

An easily recognisable weed found in lawns. Also known as Dutch Clover. This weed prefers a good soil condition often in a shady and damp area. Leaves of this weed are known by its three leaves, occasionally found as four (Known to be lucky for some). Inches Each leaflet is 0.6 – 1.2 cm (1/4 to 1/2 inch) long. Generally white in appearance, the white flowers are often found above the leaves, and can bloom for the majority of the year.

Why is it a problem for your lawn?

It self-seeds and can colonise quickly throughout your lawn, choking out grass with its creeping runners that travel along the surface very quickly.

Control

Getting rid of White clover starts with having a healthy strong grass lawn. Clover will grow in areas of low nitrogen and where a competition of other plants is low, so it is well advised to fertilise your lawn which will help your desirable grasses to flourish and keep white clover at bay. You can attempt to hand weed this plant, but you must make sure the root system is fully removed otherwise it will simply grow again. For larger more troublesome areas you should use an Herbicide, but again, if the root system is not reached it will grow back.

Bindweed flowering

leaf of bindweed lawn weeds

BINDWEED Calystegia sepium

 

Type: Perennial Broadleaf

Height: Can grow up to 1.9 metres (6ft) long

Flowering May through to September

 

 

What’s it like?

Bindweed or Bellbind is also mistaken for Morning Glory with its pure white flowers resembling a trumpet. A familiar site amongst UK gardens and lawns. It will choke other plants by wrapping its stem around them and smothering them. It is mostly problematic in long grasses. Very difficult to remove as they have a very strong root system. If broken they are easily able to regenerate.

Why is it a problem for your lawn?

This weed spreads mainly from sections of its underground stem (rhizome) or root. They can reach up to 16 feet (5m) deep and will spread very quickly. This invasive weed can be brought into your garden lawn amongst other plant roots and manure. They will stay in the soil for many years.

Control

Due to the strength and length of their root system, this weed is very difficult to remove completely. Persistent digging out may prove to be futile as often you will unwittingly leave part of the root system in the soil. If you use a chemical control (Herbicide) containing glyphosate it will be applied to the foliage where it will be translocated throughout the weed. It is important to avoid spray drift and to have good leaf coverage so you get as much of the chemical absorbed as possible. This is more effective when bindweed is flowering. It is important to check the manufacturer’s instructions so you avoid killing off delicate plants nearby. Regular mowing and the use of lawn weed killers will help keep them under control and will eventually eliminate this nuisance weed.

Flowers of Yarrow lawn weeds

leaf of yarrow lawn weeds

YARROW Achillea millefolium

 

Type: Perennial Broadleaf

Height: Up to 1 meter (3ft)

Flowering: Mid May through to July

 

 

What’s it like?

A common weed appearing on all types of lawns. It spreads by creeping stems, rooting at intervals. It has deep fibrous roots and can withstand dry conditions. The leaves resemble the fern, making it easy to identify. Yarrow is a mat-forming rhizomatous plant with aromatic grey/green foliage resembling a fern. It produces white or pinkish/white flowers. It will regrow vigorously from the underground creeping stems and seeds. It will take over lawn grasses.

Why is it a problem for your lawn?

Yarrow thrives in chalky soils where plant nutrients are low and is very drought resistant. When your lawn’s grass is weakened by long periods of drought together with poor nutrient levels, Yarrow will thrive and very quickly establish itself in your lawn.

Control

Once Yarrow has established itself in your lawn it is very difficult to control. By applying a top-dressing in early Spring you will encourage vigorous grass growth making it more difficult for Yarrow to thrive. Feeding your lawn when your grass is growing with a quality fertiliser in Spring and Summer will also help. However, if your lawn is drought stressed do NOT feed it. A regularl lawn mowing and lightly raking it will also help to weaken the weed and strengthen your grass. Yarrow is quite resistant to many selective weed killers that can be found in DIY garden centres. However, if you do choose to apply weed killers yourself then repeated applications of products can be effective.

mouse ear chickweed lawn weeds with flowers

leaves of mouse ear chickweed lawn weeds

MOUSE EAR CHICKWEED Cerastium

 

Type: Perennial Broadleaf

Height: 5-20 cm (2 – 8 inches)

Flowering: April through to November

 

 

What’s it like?

Mouse-ear Chickweed is a very common weed found in lawns. It spreads very quickly forming a dense mat on your lawn. The leaves are small oval and dark green, fleshy and covered with fine hairs. They will thrive in all types of soil conditions and will tolerate a close mowing. The white flowers appear in clusters and can be seen as early as April and last until November. Each flower produces 5 petals which are deeply lobed which gives the appearance of 10 petals.

Why is it a problem for your lawn?

As this weed can tolerate a close mowing it will be a nuisance on fine luxurious lawns. It has a shallow fibrous root system which will spread by its nodes and by seed.

Control

Mouse-ear chickweed is a difficult weed to control by hand because of its growth characteristics so is really only practical for a few plants. Like most lawn weeds they can be discouraged by keeping your lawn in a healthy condition with good maintenance practices. In some cases reducing the shade may help reduce the problem. If the problem is severe then a chemical control will be needed. As Mouse-ear Chickweed is susceptible to a wide range of chemicals, most products can be used to control this weed. One application is usually enough to kill Mouse-ear chickweed. Aim to treat Mouse-ear chickweed during the first signs of the weed and when growth is strong for the best results. Once the weed has been removed or controlled the bare area can be filled with a mixture of suitable soil and grass seed to aid recovery.

daisy flower lawn weeds in a lawn

leaves of Daisy lawn weeds

DAISY Bellis perennis

 

Type: Perennial Broadleaf

Height: 10 -16 cm (4 – 6 inches)

Flowering: May through to October

 

 

What’s it like?

One of the most recognisable lawn weeds. This weed is also known as English Daisy, Bruisewort and Lawn Daisy. This perennial weed has a yellow centre surrounded by white petals and fleshy round leaves. It grows approximately 3-inch. They will appear from Spring to Early Autumn. It is resilient to regular mowing, often needing a daisy grubber for quickly lifting and removing the weeds. It is resilient to most soil conditions. It can survive in closely mown lawns due to its round leaves which grow very close to the ground.

Why is it a problem for your lawn?

This weed will tolerate close mowing as it grows close to the ground. They should be removed to enable you to get a lush green lawn that is even in colour and appearance. It spreads by forming mats of foliage and is able to colonise new areas by producing seed.

Control

If you only have a small number of these plants in your lawn you can remove by hand with a daisy grubber. If however, you have a larger infestation you will need to use a Chemical (herbicide) solution. If it is possible you should only spot treat the area so as not to kill other delicate plants. A repeat treatment may be necessary approximately six weeks after the first treatment as the daisy can be a difficult weed to kill in one single treatment. After the weed has been removed you may need to repair the bare area with an over-seed and top dressing to help it recover.

Nettle lawn weeds with flowers

leaves of Nettle lawn weeds

COMMON NETTLE          

(Stinging)

Urtica dioica L.

 

Type: Perennial Broadleaf

Height: Can grow 2 to 4 metres

Flowering: May to September

 

What’s it like?

The common nettle is a leafy plant that is found in most regions of the world. The Nettle plant grows erect on stems. These are up to 120 cm tall and covered with stinging hairs on the leaves with short bristly hairs on the stems. It can grow approximately 2 to 4 metres high and will produce pointy leaves that eventually turn into white to yellowish flowers. Nettles are very well known to give a nasty sting when the skin touches the hairs and bristles of the plant. Nettles have large yellow rhizomes that enable the plant to spread and reproduce itself quickly.

Nettles can reproduce themselves from seed and rhizomes that form underground stems that extend out and grow, producing new shoots, enabling the nettle plants to spread.

The flowers formed in drooping panicles, growing in groups from the upper leaf. The species name dioica means ‘two houses’ because the plant usually contains either female or male flowers.

Why is it a problem for your lawn?

Nettles can grow on most soil types and can tolerate drier soils. This plant can quickly establish itself on waste and neglected grounds.  Nettles have large yellow rhizomes that enable the plant to spread and reproduce itself quickly.

Control

Nettles can be controlled with a regular cutting back which will weaken the plant until it eventually dies. You can remove the entire plant ensuring all roots and rhizomes are completely dug out and moved away from the area.

For chemical control, you can apply a non-selective herbicide. These chemicals are best used when the weeds are actively growing, usually between April-October.
These herbicides are usually applied as a liquid using watering cans or sprayers.

Control

Just like many other fast-growing weeds, this plant has to be carefully controlled. Proper preventative lawn maintenance is required to keep on top of this weed. If you only have a small number of these plants in your lawn, they can be removed by hand with a daisy grubber. Gloves should be worn when removing this weed as it can cause skin irritation and has a very strong smell. A larger infestation will need a Chemical (herbicide) applied.  Remember to dispose of this weed in areas that are not accessible to animals. If Mayweed has taken over large areas of your lawn, then it is advisable to contact a professional lawn care company to handle it remove it. Bare areas will need an over-seed and top dressing to help your lawn recover

close-up of Pearlwort leavesPearlwort lawn weeds with flowers

PEARLWORT

(Sagina procumbens)

Type: Perennial

Height: :  4 – 10 cm high (2 – 4 in)

Flowering: April to September

What’s it like?

Pearlwort is a perennial mat-forming plant with small white flowers and narrow leaves. It populates most soil conditions and seeds very quickly. It is often mistaken for Moss in lawns and it likes moist and wet conditions. It produces fine like roots that can invade most soil conditions. It’s small white flowers are found on long stems near the tips of the branches of this weed.

Why is it a problem for your lawn?

An invasive weed which is a problem for close cut lawns. Pearlwort produces a high amount of small seeds, which spread by mowing and foot traffic. It can become a nuisance weed when allowed to spread and establish itself in your lawn’s turf.

Control

Keep your grass swards dense and healthy to prevent Pearlwort establishing itself in your lawn. Good lawn care maintenance such as Aeration, regular mowing, fertilisation will ensure your grass sward is dense. It is best to eradicate this weed as quickly as possible, as it can be very difficult to control once it is well established. It can be sprayed with a weed killer that is absorbed through the leaves of this plant, this way the active ingredient of the weed killer will work its way through the cells and down to the root, to kill it off. It may need repeat spraying 6 – 8 weeks.

dandelion lawn weeds with flowers

leaf of dandelion lawn weeds

DANDELION Taraxacum officinale

 

Type: Perennial Broadleaf

Height: 50 cm or more (20 in)

Flowering: March through to November

 

 

What’s it like?

The Dandelion is a common perennial weed. Although it is a perennial plant it spreads from seed and germinates throughout the year. The seeds are wind-borne and often found germinating along the edges of garden borders. It has a long stout tap root which stretches up to 10 inches. The Dandelion leaves have known health benefits and the flowers are often made into wine. The leaves are long and fleshy and can grow to a quite a large size, anywhere from 3 -12 inches. The leaves are simple and basal, forming a rosette above the central taproot. The flower heads are yellow to orange and are open in the daytime but closed at night time.

Why is it a problem for your lawn?

This weed is very persistent. They will spread quickly by seed and will colonise in freshly cultivated soil. They are also able to survive in compacted soil conditions. Because they have a deep root it allows them to survive and re-grow when the top of the plant is removed. These weeds will crowd out your grass and create a patchy and problematic lawn. Your lawn will be uneven in appearance.

Control

A thick and healthy lawn is certainly the best defence against this and similar broadleaf weeds. Pulling these weeds out by hand can be very difficult as their taproot is can stretch down very deeply into the soil, if you are attempting this you should remove them before they go to seed. There are two types of chemical (herbicide) weed killers that can be used on dandelions. The first is a selective broadleaf herbicide. A broadleaf herbicide will only kill broadleaf weeds, such as dandelions. By using a broadleaf herbicide it will kill the dandelions and not the grass. The other kind to use is a non-selective herbicide. Be careful when using this type of product as it will kill any other plant it comes into contact with. A non-selective herbicide is effective for spot dandelion removal. When using an herbicide to control Dandelions it is best to apply it before the weed has developed flowers.

Creeping buttercup will spread by long runners with deep penetrating roots. They have sub-lateral runners that will develop into a vigorous network of firmly anchored stems in your lawn. They will reproduce from seeds in moist conditions.

Control

The runners of this weed can be dug out in Spring with a trowel. In the Spring months before mowing you can use a wire rake to lift the developing runners so they can be more easily cut by the mower. By using a Chemical (Herbicide) weed killer you can control this weed. Apply in Spring when the growth is strong and repeat the application if necessary. It is not advisable to use a Non-Selective herbicide as it can come into contact with desirable plants.

flower of narrow-leaf plantain lawn weeds

Narrow-leaf plantain lawn weed in a lawn

NARROW-LEAF PLANTAIN Plantago lanceolata

 

Type: Perennial

Height: 10–40 cm (4 -16 in)

Flowering: April through to October

 

 

What’s it like?

A very common lawn weed found in all types of lawn conditions. Noticeable because of its long, narrow dark green leaves with distinctive ribs and fine hairs. It likes both wet and dry conditions and can resurface easily after removal, it will grow throughout the year. It has short flowers on a long stem.

Why is it a problem for your lawn?

Plantain can often be an indication that you have a soil compaction problem as they like alkaline dry and compacted soil.

Control

You can attempt hand weeding if there are only a few plants in your lawn, but be careful to remove the entire root or the weed will regenerate again. A regular mowing will prevent the seed heads forming and reduce spreading. If your soil is compacted, a lawn Aeration will help encourage a healthy sward and will, in turn, discourage ribwort Plaintain in your lawn. For a larger infestation, you will need to use a chemical (herbicide) control. Most selective weed killers available should deal with this weed but you will need to treat it again in approximately six weeks later.

a lawn with flowering broadleaved-dock lawn weeds

broad-leaf dock lawn weeds in a lawn

BROAD-LEAVED DOCK Rumex obtusifolius

 

Type: Perennial Broadleaf

Height: 50 to 130 cm (1 ½ ft – 4 ½ ft)

Flowering: June through to September

 

 

What’s it like?

Broad-leaved dock is one of the most common weeds in grass lawns and particularly in neglected lawns. They can survive drought and poorly nourished soil conditions due to their very deep tap roots. The flowers are green but go a reddish colour in maturity. It has large oval leaves, some of the lower leaves have red stems.

Why is it a problem for your lawn?

If docks are present in your lawn it is often because there are bare patches. Poor lawn maintenance will allow dock seedlings to emerge and grow. Broad-leaved dock is able to grow on a range of soils except for the most acidic ones. Soils high in nitrogen or low in potassium are preferred conditions. This weed is an unsightly addition to your lawn and will make it look very uneven in appearance. It is also considered to be slightly poisonous.

Control

It is not too difficult to permanently control this type of weed. It requires a deep digging out and can take a lot of effort and time as you will need to remove every part of this weed without breaking any pieces, and if there are any remaining pieces they will simply re-sprout. For larger infestations, you will want to use a Total weed-killer, such as glyphosate and spray directly on to the plant. It is always best to avoid spraying on a windy day as the product will make contact with other desirable plants.

An invasive weed that will happily take over wanted plants in your garden

Control

Red Clover can be controlled with cultural practices, including proper lawn mowing and watering. Physical removal (i.e. “weed pulling”) can be effective, although you will run the risk of spreading the seeds to additional areas of your lawn and landscaping. Glyphosate is a common ingredient in over the counter herbicides and can be effective as red clover weed control. Be careful not to allow this herbicide to drift on to surrounding plants as they could be affected as well. If the infestation is hard to kill a professional lawn care company will use a specially selected herbicide to kill this weed as it will move throughout the weed killing it completely including the root and safeguard surrounding wanted plants.
