Bamboo is an increasing problem in the UK, particularly in residential gardens. The plant can be categorised into the ‘clumping’ and ‘running’ types, but it’s the running types in particular that cause issues for homeowners. #JKSL #bamboo #invasiveSpeciesWeek #INNSweek

“Giant hogweed, stay away from me!" the toxic chemicals (furanocoumarins) in the sap inside the leaves + stalks of Giant hogweed can react with the sun’s UV light (reaction called phytophotodermatitis) causing phototoxic burns to the human skin #JKSL #InvasveSpeciesWeek #INNSweek #Gianthogweed

When treating Giant hogweed, full PPE must be worn at all times. Best advice, leave it to the professionals! #Gianthogweed #INNSweek

A usual suspect, Himalayan balsam, which can often be found along pathways and watercourses. When fully mature it will grow to around 2-3m in height, eventually releasing its seeds in August/September. Don’t blink or you’ll miss it! Here's a vid from last year. #JKSL #InvasiveSpeciesWeek #INNSweek #himalayanbalsam

Horsetail is now in its main green vegetative growth stage. Although native, it is regarded as invasive in the UK and can cause defects to hardstanding areas such as tarmacadam pavements and driveways. Effective treatment and remediation options are available. #JKSL #horsetail #INNSweek

......prunings or impacted soils associated with schedule 9 invasive non-native plants (classified as controlled waste) should be managed appropriately 'on-site' or disposed 'off-site' at an appropriate licenced facility by a licenced haulier with the correct paperwork #JKSL #invasiveSpeciesWeek #INNSweek

“I’m confused … my nan has got Cotoneaster in her garden which is a Schedule 9 invasive non-native plant species as included within the Wildlife and Countryside Act 1981…. What can she do!?!”.... #JKSL #invasiveSpeciesWeek #cotoneaster #INNSweek

Well, some schedule 9 non-native invasive plant species (such as Cotoneaster, Montbretia, Japanese rose) are still sold at garden centres. Gardeners are encouraged to be responsible when growing them at home, however …… #JKSL #Japaneserose #invasiveSpeciesWeek #montbretia #INNSweek

The UK’s native bluebell is under threat from the Spanish bluebell, which is more vigorous, outcompeting against resources such as light & space. Is more stringent control of the Spanish bluebell now required in the UK? #JKSL #spanishbluebell #invasiveSpeciesWeek #INNSweek #bluebell

[Japanese Knotweed @JKSLtd]

So many beautiful bluebells in flower at the moment. The UK accounts for around 50% of the world’s population of bluebells, however, you may notice that not all is as it seems…. look closer…. #JKSL #invasiveSpeciesWeek #INNSweek #Bluebells
