A weed wipe can be used for small infestations although in all likelihood a small area would be easier to control by physically removing it by pulling it up. [21][22] Himalayan Balsam grows very rapidly which necessitates readily available access to soil moisture which is why it has colonised river banks which have an abundance of moisture and nutrients. ", "The biology of invasive alien plants in Canada. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. The first indications that this would be a potentially invasive plant were the county Floras showing Himalayan Balsam tracing the line of waterways through the counties. Introduced to the UK in 1839, Himalayan balsam is now a naturalised plant, found especially on riverbanks and in waste places where it has become a problem weed. One Himalayan balsam plant is said to be able to spread 2,500 seeds alone; surveyors advise homeowners to remove this weed due to its ability to … Leaves are stalked, oblong to egg-shaped and have a serrated edge. Grow on stem in whorls of three. The Himalayan Balsam is a very adaptable survivor, to the rear of my border in amongst the Atlantic Delpiniums, (which I've removed the flower stems from as they are over and done with,) there are maybe a hundred HB's, but they are only max 18 inches tall and single stemmed, yet over in the wet ground with the montbretia (now there's a plant you cant get rid of) and the various flavours of mints and aqualigia … Himalayan Balsam tends to grow near water and therefore the selection of an appropriate herbicide is limited. The genus name Impatiens, meaning "impatient", refers to its method of seed dispersal. The pulling technique must be undertaken so that whole plant is uprooted and normally best done if pulled from low down the plant - If snapping occurs at a node the pulling must be completed to include the roots. Even if you accidentally cause this plant to grow you could face criminal charges. This method can also be used in conditions which would prevent foliar application of a herbicide. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. )[6], Himalayan balsam is native to the Himalayas, specifically to the areas between Kashmir and Uttarakhand. Spraying needs to occur before the plant starts to flower but after the seed leaves have disappeared – from April to June to ensure that all the plants available for germination can be controlled. The flowers are also edible and are used in jellies and wines. What is Himalayan balsam? The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. Himalayan Balsam is not a native species to the UK originating, as the name implies, in the Himalayas. "The Plant List: A Working List of All Plant Species", "Gastronomie: Springkraut & Co.: Kräuterkoch Peter Becker macht aus Neophyten Salat", "Which flowers are the best source of nectar? Commonly found along riverbanks and streams, around ponds and lakes, in wet woodlands and in ditches and damp meadows. The flowers are pink, with a hooded shape, 3 to 4 cm (​1 ⁄4 to ​1 ⁄2 in) tall and 2 cm (​ ⁄4 in) broad; the flower shape has been compared to a policeman's helmet. Himalayan balsam also promotes river bank erosion due to the plant dying back over winter, leaving the bank unprotected from flooding.

Himalayan Balsam (Impatiens glanulifera) is an attractive looking flower, with a stout, hollow stem, trumpet shaped pink/white flowers and elliptical shaped green leaves. Grazing by cattle and sheep is effective from April throughout the growing season. Plants must be cut below the lowest node to avoid reflowering. As an annual it has a very shallow root system, barely adequate for its tremendous height. [3] Ornamental jewelweed refers to its cultivation as an ornamental plant. Colonising rail and river banks, wastelands and woodlands, Himalayan balsam was introduced to the British Isles in 1839 by Victorian plant hunters who were keen on its beautiful pink flowers and exploding seed pods. Plants have a thick, much branched, purple to reddish tinged stems. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam.

[23], Himalayan balsam at Bank Hall, Bretherton, Lancashire, England, "Policeman's helmet" redirects here. [13], Himalayan balsam is sometimes cultivated for its flowers. [5], The plant was rated in first place for per day nectar production per flower in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. Within ten years, however, Himalayan balsam had escaped from the confines of cultivation and begun to spread along the river systems of England.[17]. Unlike Japanese Knotweed, Himalayan Balsam propagates via seeds, which will explode upon touch when ready. Himalayan balsam is an annual, however, and it dies back in the winter, leaving bare spaces that would normally be inhabited by native grasses. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. [17] However, a study by Hejda & Pyšek (2006) concluded that, in some circumstances, such efforts may cause more harm than good. It is, however, a good nectar plant for bees and wasps in late summer. It grows in dense stands and can be up to 2m tall. The crushed foliage has a strong musty smell. It has an explosive seed capsule, which scatters seeds over a distance of up to 7m. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. Due to its seasonal nature, Himalayan balsam can leave entire stretches of riverbanks bare during the winter, leaving the area more susceptible to land erosion. What does Himalayan balsam look like? Plants have a poor root structure so it is relatively easy to remove. All Himalayan balsam plants germinate from the previous year"s seed. It should be continued until no new growth occurs. © 2020 Agrovista UK Ltd - Pitchcare.com is a trading name of Agrovista UK Ltd, a company registered in England and Wales.

Himalayan Balsam is a member of the Balsaminaceae family; also known as Touch-me-not Balsam and Policeman"s Helmet because of the shape of the flowers. It successfully competes with native plant species for space, light, nutrients and pollinators, and excludes other plant growth, thereby reducing native biodiversity. Leaves are long, slender and shiny, with serrated edges and are dark green in colour. The researchers caution that their conclusions probably do not hold true for stands of the plant at forest edges and meadow habitats, where manual destruction is still the best approach. 2-4-D amine is the active ingredient in Depitox, a selective herbicide that controls broadleaved weeds and correctly applied will not damage grasses thereby preventing new Himalayan Balsam seeds from becoming established however 2-4-D amine is a professional herbicide and requires the user to have a pesticide application license. Spraying needs to occur before the plant starts to flower but after the seed leaves have disappeared – from April to June to ensure that all the plants available for germination can be controlled. Like many flowering plants, Himalayan Balsam produces a sugary nectar to attract insects. Plants are very invasive and can cover large areas – particularly close to watercourses. Himalayan Balsam is the tallest annual plant in the UK growing up to 3 metres in height a year. Green to red. The common names policeman's helmet, bobby tops, copper tops, and gnome's hatstand all originate from the flowers being decidedly hat-shaped. Destroying riparian stands of Himalayan balsam can open up the habitat for more aggressive invasive plants such as Japanese knotweed and aid in seed dispersal by dropped seeds sticking to shoes. Himalayan Balsam regrows annually from the seeds which are viable for 2 years therefore any control ... Leaves Green large narrow leaves with serrate edges. Himalayan balsam has a very shallow root making uprooting by hand easy. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, nectar. Its aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allow it to outcompete native plants. [17][18] These plants were all promoted at the time as having the virtues of "herculean proportions" and "splendid invasiveness" which meant that ordinary people could buy them for the cost of a packet of seeds to rival the expensive orchids grown in the greenhouses of the rich. [16], In the UK, the plant was first introduced in 1839, at the same time as giant hogweed and Japanese knotweed. [7], In Europe the plant was first introduced in the United Kingdom where it has become naturalized and widespread across riverbanks. This causes a problem because Himalayan Balsam does not have an extensive root system and it is crowding out perennial plants that bind the river banks with their root systems. A very invasive, non-native plant which is illegal to grow or cause the growth of. Glyphosate is the active ingredient in Roundup Pro Biactive, it is a very effective herbicide that starts to degrade almost as soon as it is applied however it is not selective and will kill any plant it comes into contact with.

The research suggests that the best way to control the spread of riparian Himalayan balsam is to decrease eutrophication, thereby permitting the better-adapted local vegetation, that gets outgrown by the balsam on watercourses with high nutrient load, to rebound naturally. [20], The Royal Horticultural Society and the Centre for Ecology and Hydrology recommend that pulling and cutting is the main method of non-chemical control, and usually the most appropriate. Himalayan balsam was introduced as a garden plant in 1839, but soon escaped and became widely naturalised along riverbanks and ditches, especially close to towns.

Himalayan balsam is an annual plant and grows very large for an annual species: up to two metres high or even more. During flood events the river banks are then vulnerable to floodwater because of the lack of perennial plants. Differences. The species name glandulifera comes from the Latin words glándula meaning 'small gland', and ferre meaning 'to bear', referring to the plant's glands. [14] Invasive Himalayan balsam can also adversely affect indigenous species by attracting pollinators (e.g. Himalayan Balsam colonises areas rapidly and quickly outcompetes the surrounding vegetation and reduces diversity. It is illegal to move soil which contains its seeds and accidentally spreading them and its … insects) at the expense of indigenous species. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. The Injectordos Pro Stem Injection Kit will limit the herbicide to treating specific plants, creating minimum disturbance in the surrounding vegetation and enabling the surrounding vegetation to spread quickly back into affected areas. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. The aeciospores enter the leaf through the stomata in a film of water, produced by dew or rain, and develop within the leaf feeding on the internal cells. Leaves are arranged opposite each other along stems. [8][9][10], In North America it has been found in the Canadian provinces of British Columbia, Manitoba, Ontario, Quebec, Nova Scotia, New Brunswick, Prince Edward Island and Newfoundland.

Roots are up to 15 cm deep, the plants often forming numerous adventitious roots from the lower nodes. [2] Via human introduction it is now present across much of the Northern Hemisphere and is considered an invasive species in many areas. [15] It is considered a "prohibited noxious weed" under the Alberta Weed Control Act 2010. Himalayan balsam typically grows to 1-3 m in height, with a soft green or red-tinged stem, and toothed leaves 5-23 cm long. The leaves are opposite, the upper ones sometimes in whorls of three, up to 25 cm long and 7 cm wide, lanceolate to obovate, petiolate and sharply serrated at the edges. In August 2014, CABI released a rust fungus in Berkshire, Cornwall and Middlesex in the United Kingdom as part of field trials into the biological control of Himalayan balsam. In terms of the negative pollinator effect with Himalayan balsam, there is evidence to suggest the opposite, that there is what they call an adjacent benefit, so that other native riparian riverside species that are flowering at the same time receive more visits rather than less when they’re kind of in the same area as Himalayan balsam, Himalayan being super popular with honeybees and … Himalayan balsam and kiss-me-on-the-mountain arise from the plant originating in the Himalayan mountains. The shallow roots allow the plant to be pulled up right up to June when it flowers. The green seed pods, seeds, young leaves and shoots are all edible.
