Plant dubbed 'new knotweed' as it invades UK gardens with reports of havoc from homeowners

Garden aficionados are sounding the alarm over a plant now being dubbed 'the new Japanese Knotweed', amid increasing reports of it causing havoc in UK homes and gardens. Homeowners have been given guidance on cultivating this species.

The trend for planting bamboo, which took off in the 2000s, has gained traction due to its low upkeep requirements. Bamboo not only brings an exotic aesthetic to gardens but also serves as a sanctuary for wildlife, offering birds, insects, and small mammals a place for shelter and sustenance.

Bamboo's status as one of the world's most rapidly growing plants makes it a top pick for those looking to establish privacy screens or windbreaks swiftly. However, certain types can spread aggressively and may become a nuisance without proper management.

A 'Bamboo crisis' is reportedly unfolding in some regions, with gardeners who were ill-advised planting invasive species that are now causing destruction to their own and adjacent properties. Chris Bonnett from GardeningExpress.co.uk commented: "Bamboo is ideal for garden designs that call for dramatic backdrops, privacy screens, or stand-alone features. You can get black and green varieties and they're very hardy and low maintenance, which is perfect for Brits that aren't that green-fingered."

"However, if you're growing running varieties it's a good idea to keep them in pots and planters in order to control the growth and spread. It's as simple as that. You should also watch out for pests like aphids and spider mites, and use natural remedies or appropriate pesticides to manage infestations.", reports the Manchester Evening News.

Gardening Express has shared some tips on how to grow bamboo safely.

Choose the right species

Opt for clumping bamboo if you want an easy-to-manage option for your garden. This type grows in tight clusters, making it less invasive.

Running bamboo, however, can quickly take over your garden space due to its underground rhizomes.

Grow in pots and planters

To prevent running bamboo from becoming uncontrollable, it's advisable to plant it in pots and planters. This method allows for easier management and pruning, ensuring the bamboo remains at the desired size and shape.

Additionally, container-grown bamboo can be moved to protect it from extreme weather conditions.

Plant at the right time

The ideal time to plant bamboo is during spring or early summer when the soil is warming up, which encourages root development.

Maintain regularly

To ensure healthy and attractive bamboo growth, proper maintenance is essential. Newly planted bamboo requires frequent watering until it establishes a robust root system, so it's important to water it thoroughly to maintain consistently moist soil without waterlogging.

Over time, bamboo clumps can become dense with many canes, leading to overcrowding. Thinning helps reduce this density, ensuring that the remaining canes have enough space to grow properly.

It also allows more light and air to reach the interior of the clump, promoting healthier growth and reducing the risk of fungal infections and other issues. Simply look for older, less productive canes that may be yellowing or showing signs of age.

These canes often have fewer leaves and are less vigorous. Use sharp pruning tools to cut these canes at ground level.

Avoid leaving stubs, as they can be entry points for diseases.
