Gardening tips: ‘most profitable’ way to banish invasive plants – how to get rid of them

Invasive plants are more than just weeds. Beyond the garden, they can cause serious economic and environmental damage, and sometimes even harm human health. Invasive non-native species generally tolerate a wide range of conditions and easily outcompete other plants with prolific seed dispersal and rapid growth rates. These successful adaptations are compounded by a lack of equalizing agents, such as pests and diseases, that would typically be present in the plants’ native ranges.

Invasive plants don’t always look obnoxious when they spread through the garden, with the pretty green leaves of Japanese knotweed and the evergreen vines clinging to the ivy providing an attractive garden display, but they do. makes it even more difficult to identify as pest species.

Harry Bodell, gardening expert at PriceYourJob shared some effective ways to get rid of invasive plants from gardens.

He explained that with plants like ivy, pruning is a great way to kill them while keeping costs down.

The expert said: “If common ivy (Hedera helix) is causing problems, the best and most cost-effective way to eliminate it is to prune it back to the base.

“Let the vine die, then you can remove it by digging up the stump.

“You should always wear protective clothing, a mask and goggles when doing this as the sap is a skin irritant and can cause respiratory problems.”

“Contact your local authority to find out where you can safely dispose of your cuttings.”

As with the ivy, with the invasive rhododendron (Rhododendron ponticum), the gardening pro suggested cutting it right away, as close to the base as possible.

Harry explained: “You might need a garden saw and loppers for this.

“Then target the glyphosate herbicide directly into the stump. You may need to reapply the herbicide if new shoots start to grow.

“Once you’re sure it’s dead, you can cut or dig up the stump. Avoid planting anything new in the ground until you are sure you have successfully eradicated it.

For those looking for a natural way to get rid of invasive plants, without harming the ones you want to keep, an expert has shared the kitchen staples you need for the job.

Tom Hilton gardening expert and director of hydroponic specialists, National greenhouse said: “For those looking for a biological method of elimination, it is possible to use vinegar as an herbicide.

“Use four parts cleaning vinegar, one part water, and a little dishwashing liquid.

“After mixing your solution well, pour it into a spray bottle and begin spraying the invasive plant in dry weather.”

Alternatively, gardeners can use a combination of boiling water and mulch to banish these plants.

The gardening professional said: “You can also pour boiling water over overgrown plants or smother them with a tarp or heavy plastic – which is a longer but effective process that works best for heavily consumed areas. “

Another method that “works well for small populations of invasive plants” is to remove them by “digging in and pulling them out,” according to Tom.

He added: “But beware, you may never be able to completely get rid of the plant and you will need to tend your garden by regularly checking to see if any new shoots have emerged.”

The expert also explained how gardeners should properly dispose of these plants.

Tom said: “The elimination phase is just as important as eliminating invasive plants.

“Without taking care to get rid of all garden waste, you risk scattering the seeds and causing more growth.

“There are a variety of methods you can use to do this – such as drowning, composting, burying, bagging and burning – but it will depend on the species you are dealing with.

“Invasive plants, such as poison ivy, produce toxic smoke when burned, so it’s critical this is avoided.”
