What do you think of when you hear the word ‘weed’? Join us as we uncover the myths #and delve into what it really means.
It’s a word we’re all familiar with, and one we hear often, especially during our annual No Mow Movement – ‘What about the weeds’?
The Cambridge Dictionary defines a weed as, ‘any wild plant that grows in an unwanted place’.
If you were asked to picture a weed, perhaps some people would think of a Dandelion pushing up through the pavement, or a lone Forget-me-not lurking in your lawn. Many people think of specific plants as ‘weeds’, but that’s not true.
So, join us as we weed out the myths of the word ‘weeds’.
Here’s the thing – the actual definition of a weed is simply, “a wild plant growing where it is not wanted, especially among crops or garden plants.”
Just a plant, in a place we didn’t choose.
Technically speaking, any plant can be a weed. Even our most treasured native wildflowers such as orchids, simply for existing in a spot we decided they shouldn’t.
So, what makes people think of a Dandelion as a weed but an orchid as a prized plant? It’s simply perception and context.
The word ‘weed’ has been part of the English language since at least the 9th century.
It’s believed to have come from the Old English word ‘weod’, which simply means a plant – including herbs or even trees.
Over time however it took on more of a negative tone, especially as agriculture became more dominant and plants that competed with crops then took on the name.
By the 19th and 20th centuries, with the rise of industrial farming and garden landscaping, ‘weeds’ became enemies. Something to spray, pull, or pave over.
But in nature there are no weeds. Just plants doing what they’ve always done – growing, spreading, surviving.
Non-Native Invasive Species aren’t weeds by definition, but they certainly can cause problems.
Non-native plants are simply plants that have been introduced to the UK, that naturally grow in other parts of the world.
Not all non-native plants become problems – many of them integrate into our habitats without causing damage (these are called ‘naturalised’ species). However, some thrive in our habitats, so much so that they out compete our native plants, these are known as Invasive Non-Native Species (INNS). These include common garden centre finds such as Rhododendron.
One in five species of UK vascular plants are at risk of extinction. The second biggest threat to biodiversity is Invasive Non-Native Plants, so they must be taken seriously.

While the majority of plants have value to wildlife, some can cause problems, mainly to other plants around them.
Think of a thicket of nettles for instance, there’s not much biodiversity in the swathe as it has a tendency to takeover. While large amounts of such plants can cause problems, small amounts are That said, it’s important to remember the benefit that plants, including nettles bring to our other wildlife. Nettles can be a great addition to your green space and support more than 40 different insects and butterflies!
So, while problem plants aren’t necessarily ‘weeds’ we recognise that some plants could benefit from some careful control. Read our blog here, to find out how to manage problem plants such as Thistle and Common Ragwort.
We ran a survey recently and found that 56% of people think of Dandelions as a weed. That’s not a huge surprise – Dandelions have had a bit of a PR problem. But the truth is, they’re not ‘weeds’ but wildflowers. And quite useful ones, at that! In fact they were once revered as a cure all medicinal herb and even appear in ancient Greek mythology.
Watch our video below to find out why we should rekindle our love of the humble Dandelion.
Dandelions are amazing! Did you know that Dandelions support more than 50 species of insects? Or that Dandelions have been used in medicine for centuries?
The good news? More than 90% of 19-24 year olds in our survey said they see dandelions and daisies as wildflowers, not weeds. This gives hope for the future of our native wild plants.
Perhaps in the future we will all see ‘weeds’ differently – as part of a bigger picture. ‘Weeds’ are our native plants and part of the planet long before we were. They make up important habitats, improve biodiversity, provide food and even medicine, they even capture carbon!
Let’s change our perspectives to see ‘weeds’ for what they really are, wildflowers that are symbols of resilience, beauty and wildness.
One of the UK’s rarest plants, Field Wormwood, has been given a lifeline to try and boost the numbers of this endangered plant.

Managing or making meadows, whether as part of your lawn or larger sites, can sometimes lead to a prickly problem, with plots of docks or nuisance nettles!
Problems can arise by opening the soil or when the nutrients are very high – but our experts are here to help.
While most plants have some value to wildlife, species such as Common Nettle Urtica dioica, thistles Cirsium sp and docks Rumex sp can spread rapidly in meadows or lawns with sub-optimal management and crowd out wildflowers. Small amounts of these species are natural in any grassland, especially along boundaries or corners, large amounts of them can indicate a problem.
However, large swathes of thistles or nettles will result in less space for a diversity of other flowering plants, which could result in a meadow being less valuable for wildlife. Also be aware that an area that has alot of these problem plants already, is usually best avoided altogether if attempting to make a new meadow area.
Preventing problem plants establishing in large numbers is better than a cure . It is best to:
Broad-leaved Dock Rumex obtusifolius can grow up to 120cm tall and has wide lower leaves that are slightly wavy-edged. The upper leaves on the flowering stem are narrower. The leaves may be slightly red tinged.
Curled Dock Rumex crispus is like Broad-leaved Dock but has narrower leaves tapered into the stem with strongly crisped edges. Docks are an important plant for a range of insects such as capsids, weevils, beetles, spiders and many other insects.
Spear Thistle Cirsium vulgare is a biennial plant, forming a rosette of spiny and sharply toothed leaves in the first year and producing large purple flowering heads in the second year.
Creeping Thistle Cirsium arvense is perennial with wavy-toothed leaves that have slender spines and smaller purple flower heads.
Common Ragwort Jacobaea vulgaris is a biennial member of the Daisy family. Its seed germinates in the autumn producing a rosette of leaves. During the second year, the plant sends up flowering shoots which have multiple yellow flowers.
Common Ragwort is known to support more than 129 other species of invertebrates and has enormous value for wildlife. It acts as a nectar source for pollinators as well as some larvae of flies and beetles which feed on the inside of the flower head. The caterpillars of the cinnabar moth eat Common Ragwort acting as a natural biological control agent. In addition, 14 species of fungi use ragwort as their host.
Common Nettle Urtica dioica is a coarsely hairy plant with stinging hairs that have a histamine-containing juice. Plants are dioecious – male or female. It has far-creeping underground rhizomes which can spread creating large clumps of common nettle.
It is an important plant for a range of insects such as ladybirds, damselflies, capsids, weevils, beetles, and spiders. Young nettles are the food plant of many moth larvae such as the snout, dot, burnished brass and younger mother-of-pearl and butterflies such as the peacock, small tortoiseshell and comma.
Many of them have seeds that are very fertile and spread on the wind, usually dropping far away from the parent plant. A single Common Ragwort plant can produce up to 200,000 seeds, and these can lie dormant in the soil for as long as 20 years. Common Ragwort is also a problem in particular for livestock as the plant contains toxic alkaloids which act as a cumulative poison eventually destroying an animal’s liver.
Some species also have rhizomatous roots that are spreading meaning that they form dense clumps in grassland. Accidently breaking up the roots when removing certain species creates larger clumps as even small bits of root can grow into plants and can remain dormant in the soil for years. For example, Creeping Thistle can create a 20- metre patch in just two years from a small bit of root left in the ground.
Spear Thistle, Creeping Thistle, Broad-leaved Dock, Curled Dock and Common Ragwort are classified under the Weeds Act 1959, under which orders can be made requiring their control to help prevent their spread. So, controlling populations of these two species should be undertaken to manage the extent of clumps as total elimination is unlikely to be achievable or desirable.
All methods of managing problem plants need patience above all else. Most often it can take years before problem plants are brought back under control.
Essentially pulling by hand is going to be the simplest and least invasive way of managing most of them, or simply cutting the heads off the plants before they flower or set seed for others. However, if you have large numbers of plants and are unable to physically remove them, then spot-spraying can be used. We would always recommend consulting an expert for suitable and available herbicides that will affect the specified problem plants and how to apply the chemicals safely. Spraying is usually most effective early in the season (May or June) before the plants’ flowers are developed. When found along the edge of watercourses, there are additional concerns about using herbicides.
It is important to take care when digging to remove some species, as Creeping Thistle for example can spread further if fragments of roots are left in the soil, whereas digging and removing Spear Thistle is not a problem.
In a well-managed sward, Common Ragwort seldom gets the chance to establish. Pulling and digging is often the most effective control method. Hand tools can be used to make the job easier such as a ‘lazy dog tool’ and a ‘rag-fork’. Gloves must be worn! This method should be done early in the summer before the flower heads mature with best results when the soil is wet. This enables the whole plant to be removed as small bits of root left in the soil can grow becoming new plants. Roots are more likely to break in dry ground potentially creating a larger problem with a halo of new plants around the removed parent plant. Cutting can be used as a method, however it is essential to cut before seed heads are mature and this must be followed with another control technique. Cutting may stimulate the growth of side shoots and vigorous growth in the following year.
Common Nettle is usually best managed through cutting by mechanical means such as a tractor-mounted cutter, strimmer or by hand, using a scythe. This method is best used where infestations of Common Nettle are small, bird nesting is not an issue, equipment and labour are available and where total control is neither desirable nor necessary. Repeated cutting combined with close mowing of the area will weaken Common Nettles and allow the grass to successfully compete over a period of years.
There are other species of thistles that are not considered problem plants, such as:
There are other Dock species that are present in grassland and are not considered problem plants in the legislation. These include:
There are other Ragwort species that are present in grassland and are not considered problem plants in the legislation. For example:
