Aphids, the sap-sucking insects that infest plants, are especially prevalent throughout the summer months. Though aphids are a food source for ladybirds and other beneficial insects, aphids damage plants, causing twisted leaves or a tacky substance called honeydew.
This can occasionally result in sooty mould, though David Austin Roses states it won’t damage your plant. Luckily, there’s a straightforward method to safeguard plants from aphids. Writing on the David Austin Roses Facebook page, Dana Dobrescu posted: “What do you recommend for my aphid infestation? All my roses are under attack. I used a commercial spray, but it was useless.”
The rose enthusiast shared a photograph of her plant, revealing hundreds of aphids encircling the bloom. Aphids can be found on the reverse side of leaves, making regular inspection of this area essential.
The post generated hundreds of responses from group members, all suggesting a homemade spray.
Linda Moran remarked: “Spray with washing up liquid and water mixed together.”
Jill Heiman advised: “You could leave them for the ladybugs to eat, but if it’s really getting to you, mix washing up liquid and water. Spray the rose and watch aphids slide off.”

Diluted washing-up liquid will disturb the pest’s habitat, though it requires application every few days, particularly after it rains.
Too much soap can damage plants, so ensure this technique is used moderately. Encouraging ladybirds into your garden is another effective method to eliminate aphids.
David Austin Roses stated: “In most cases, aphids are best left alone. They’re an important food source for ladybirds, hoverflies and other beneficial insects and play a crucial role in your garden’s ecosystem.
“If their numbers increase, a strong spray of water is usually enough to reduce them.
‘You can also gently rub them away or encourage natural predators by planting companion plants like parsley, yarrow or nasturtiums.”
