As we begin clearing gardens for winter, many people don’t realise that a simple green waste bag could land them with a hefty fine – and it’s not just the council who can penalise you
As frost creeps in and we begin clearing gardens for winter, many people don’t realise that a simple green waste bag could lead to serious fines.
Gardeners across the UK are being reminded that disposing of certain plants – particularly invasive species – incorrectly could result in penalties of up to £5,000 or more.
According to waste management expert Ali Lijee of Rubbish.com, you must remember: “If the species is invasive, you cannot just chuck it in the green bin and forget about it.”
The risk of fines increases during seasonal clean ups when garden waste piles up quickly. Lijee says: “In the autumn and winter, when we clear out over-grown beds, pull up summer perennials and rake leaves and stems, the temptation to bag everything and hand it to the council is high, but wrong disposal could cost you dearly.”

“While many local councils publish their garden-waste guidelines online, the tricky bit is recognising what goes in the bin and what doesn’t. Specifically, plants that are classed as invasive non-native species must be handled with care, or legal consequences may follow,” the pro explains.
Some of the most common culprits include Japanese knotweed, Giant hogweed, Himalayan balsam, Rhododendron ponticum, and New Zealand pygmyweed – each of which appears on the government’s list of restricted species.
Lijee says: “In autumn you might be clearing out the old border, chopping down last year’s foliage, disposing of pond plants or dead shrubs, with lots of potential to make a mistake. If you toss in material from one of the listed species you risk not just a fine but possible prosecution.”
Under the law in England and Wales, it’s illegal to “import, keep, breed, transport, sell, grow, cultivate or allow to reproduce” any of the listed invasive alien plants – even if they originate from your own garden. That means they must never be added to your standard green waste collection.
If local authorities detect restricted material in a green waste bin, consequences depend on the severity. Minor contamination – like food scraps, pet waste, or soil – may result in a warning or a small fine of around £100. But repeated violations or disposal of invasive species can bring fines of up to £5,000, or even higher for businesses. In extreme cases, prosecution for environmental harm is possible.
“With winter around the corner, and with fallen leaves, spent shrubs, pond plants and soil being moved about, now is a good time to check what you’ve got,” Lijee advises. “Ask yourself: is this simply garden clippings, or could it be something that’s legally controlled?”
To help your autumn/winter garden clear-up go smoothly, Lijee shared a few extra pointers that many gardeners don’t know:
1. Recognise the high-risk plants
“Those five I mentioned are the most infamous. For example, Japanese knotweed is a nightmare: its rhizomes can survive freezing temperatures and re-sprout, and it is classed as ‘controlled waste’ in the UK.
“Giant hogweed is hazardous not only for ecology but also for humans — its sap can cause skin blistering when exposed to sunlight,” says the expert.
2. Don’t assume that one bin rule fits all
“Just because your council collects garden-waste bins doesn’t mean every plant/clipping qualifies. Soil, animal waste, food waste and invasive plants should usually go through a different route. If you pop them in the garden waste bin you may be contaminating the batch, and that can lead to your service being suspended,” says Lijee.
3. Use the right disposal route
“If you discover an invasive species on your property, you will likely need to use a licensed waste carrier and an approved disposal facility, or follow detailed advice from the GB Non‑Native Species Secretariat.
“Composting at home won’t always kill the seeds or roots of aggressive plants, so ‘green bin’ is not a safe option,” says the expert.
4. Don’t wait for spring to deal with it
“Autumn and winter are perfect times to get on top of things. When plants are dying back, you can clearly assess what belongs where, check borders and ponds and remove problem plants before they spread underground or into waterways.
“Local councils generally give one or two warnings before moving to enforcement. But the best approach is to assume that if you are unsure whether a plant qualifies as invasive, check the list or contact your council before dumping it,” the expert advises.
