UK gardeners are likely to have encountered common or English ivy, an evergreen climber that forms dense mats of growth on walls, fences and trees. Despite its benefits, such as providing shelter for birds and pollinators, it can smother plants, damage mortar in older walls, and block sunlight, making it a nuisance for many.
While most fast-growing weeds are dealt with using harsh chemicals, irrigation experts at Drip Works suggest a natural mixture of three household ingredients can effectively eliminate “serious and invasive” ivy. There are various methods to handle unwanted ivy, depending on where it’s growing. A vinegar-based spray is particularly effective for climbing ivy.
“If you want an ivy-free garden wall, this is an effective and natural way to achieve it,” the Drip Works team advised.
The recipe involves apple cider vinegar, salt, and dish soap, which when mixed together, has been “proven to be the best solution to kill ivy”.
It’s simple to make – all you need are the three ingredients and a spray bottle. Add one gallon of apple cider vinegar to the bottle, along with one tablespoon of salt, and one ounce of dish soap (approximately two tablespoons).
Both apple cider vinegar and white vinegar have their merits in the battle against ivy, with apple cider vinegar potentially packing a punch due to additional substances alongside acetic acid.
The potency of these vinegars hinges on the acetic acid concentration, which varies across different varieties.
Before application, ensure the solution is well mixed by securing the lid and giving it a good shake. Donning gardening gloves, long sleeves, and boots is essential for safety during the process.
Experts in irrigation advise that the vinegar concoction should coat the ivy for at least five days before assessing its impact.
This homemade herbicide saps the life from ivy leaves and erodes their protective waxy layer.
The team at Drip Works suggested: “After five to six days, use garden shears and a pruning saw to remove dead ivy that is clinging firmly to the building.”
If any leaves withstand the initial treatment, persistence is key; repeat the procedure until the English ivy surrenders completely.
Once the greenery has wilted, uprooting the remnants is crucial, as ivy can stubbornly resurface from even the tiniest root fragment left in the soil.
While ivy can provide a haven for wildlife, unchecked growth may compromise trees by burdening them and vying for sunlight and moisture.
