Our gardens are bursting into bloom, but sap-sucking aphids also have their eyes on our prized plants — including roses and dahlias.
If you notice an aphid infestation this spring, the good news is that you don't need harsh chemicals to fight back: there's a clever companion plant they can't stand — ginger.
According to a study published in Horticulturae, ginger can significantly help to repel aphids due to its strong-smelling aromatic compounds. You could either grow ginger near your affected plant or blend 100g of ginger with water and spray it on the infested plants (target the underside of leaves).
"Aphids tend to gather in groups rather than appearing individually, so you'll often spot dense clusters packed onto soft, new growth," says Tessa Cobley, plant pest expert and owner of Ladybird Plantcare.
"They can be green, black, brown, or even pink depending on the species, and are usually found around shoot tips, unopened buds and the undersides of leaves where they're a little more sheltered."
Tessa also recommends another clever trick for keeping the pests away: "One of the simplest and most effective ways to prevent aphids is by encouraging their natural enemies. Ladybirds, lacewings and other beneficial insects are voracious aphid predators and can help keep populations under control."
For smaller aphid outbreaks, use a quick blast of water on affected areas to hose them off.
"Pinching off heavily affected shoots can stop them spreading," adds Tessa. "With a little vigilance and a few eco-friendly techniques, aphids don't have to spell disaster. By working with nature rather than against it, gardeners can protect their plants, support wildlife and enjoy a thriving garden throughout the season."
Squishing off the aphids is also a trick that gardener and Country Living columnist Jo Thomson recommends.
"I deal with the worst by means of a finger-squish, but I leave some for the baby blue tits who, if unable to achieve their requisite hundred caterpillars a day, move to aphids as their next choice. There's nothing more satisfying than seeing them pick a plant clean."
