The seeds of Himalayan Balsam are viable for up to two years and are commonly transported in waterways. Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. Asteroid Biocare 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. [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. In its native range it is usually found in altitudes between 2000–2500 m above sea level, although it has been reported in up to 4000 m above sea level. [7] Presently it can be found almost everywhere across the continent. Himalayan balsam has a very shallow root making uprooting by hand easy. It has highly visible pink flowers on fleshy hollow stems that are green in the spring but become red as the year progresses. Grow on stem in whorls of three.

Cutting the plants down to ground level can stall their progress, but by sure to plan your attack for the end of June; too late and you risk spreading the seeds, too early and you risk precipitating a regrowth of new stems. [2] Via human introduction it is now present across much of the Northern Hemisphere and is considered an invasive species in many areas. Cutting, strimming or pulling on a regular basis for about three years will be effective and may even eradicate the plant from isolated sites. After flowering between June and October, the plant forms seed pods 2 to 3 cm (​3⁄4 to ​1 1⁄4 in) long and 8 mm broad (​1⁄4 in), which explode when disturbed,[4] scattering the seeds up to 7 metres (23 feet). Below the leaf stems the plant has glands that produce a sticky, sweet-smelling, and edible nectar. It typically grows to 1 to 2 m (3.3 to 6.6 ft) high, with a soft green or red-tinged stem, and lanceolate leaves 5 to 23 cm (2.0 to 9.1 in) long. It is, however, a good nectar plant for bees and wasps in late summer. 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. I found a reference to a distillery adding dried Himalayan Balsam flowers to one of its gins to create a limited pink edition, but they didn’t share their recipe, so I decided to create my own. The crushed foliage has a strong musty smell. The seeds have a pleasant nutty taste and seem better when pale in colour before turning black and becoming quite hard. Himalayan Balsam is tolerant of shade and it is now impossible to map the location of rivers using distribution maps of Himalayan Balsam because it has moved into woodland habitats and moist soils too. Himalayan balsam is an annual, however, and it dies back in the winter, leaving bare spaces that would normally be inhabited by native grasses. Plants must be cut below the lowest node to avoid reflowering. Plants have a poor root structure so it is relatively easy to remove. This country later included it towards the end of 2011. [3] Ornamental jewelweed refers to its cultivation as an ornamental plant. 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. Himalayan balsam (Impatiens glandulifera) has rapidly become one of the UK’s most invasive weed species, colonising river banks, waste ground and damp woodlands. 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. No need to register, buy now! The species name glandulifera comes from the Latin words glándula meaning 'small gland', and ferre meaning 'to bear', referring to the plant's glands. Grow up to 3m high. 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.

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. 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. 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. There are also claims that the height of the plant causes a problem by restricting the flow of the river. A distinctive characteristic of the plant are the seed capsules which provide its alternative name "Touch-me-not" Balsam. If all goes well, the project will have it financing its own eradication. © 2020 Agrovista UK Ltd - Pitchcare.com is a trading name of Agrovista UK Ltd, a company registered in England and Wales.

Riparian habitat is suboptimal for I. glandulifera, and spring or autumn flooding destroys seeds and plants. The plant has had plenty of time to establish in the UK and, over the last 50 years, has spread rapidly. [17] However, a study by Hejda & Pyšek (2006) concluded that, in some circumstances, such efforts may cause more harm than good.

The green seed pods, seeds, young leaves and shoots are all edible. Despite its large size its root system is fairly shallow, only to about fifteen centimetres deep. insects) at the expense of indigenous species. The elliptical leaves and side branches arise in whorls of 3-5 from stem joints. 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. Its aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allow it to outcompete native plants. As an annual it has a very shallow root system, barely adequate for its tremendous height. The shallow roots allow the plant to be pulled up right up to June when it flowers. It typically grows to 1 to 2 m (3.3 to 6.6 ft) high, with a soft green or red-tinged stem, and lanceolate leaves 5 to 23 cm (2.0 to 9.1 in) long. The green leaves are long and pointed and typically around 5 to 8 cm in length. It successfully competes with native plant species for space, light, nutrients and pollinators, and excludes other plant growth, thereby reducing native biodiversity. 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.

The capsules open explosively when touched spreading the seeds up to 7 metres enabling the … Himalayan balsam is an annual plant and grows very large for an annual species: up to two metres high or even more. 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. Himalayan balsam tolerates low light levels and also shades out other vegetation, so gradually impoverishing habitats by killing off other plants. Himalayan Balsam (Impatiens glanulifera) is an attractive looking flower, with a stout, hollow stem, trumpet shaped pink/white flowers and elliptical shaped green leaves.
