Sap-sucking aphids are problematic for currant bushes. In spring, they cause the foliage to become blistered and puckered, as well as discolouring areas, leaving yellowish-green or red patches. The aphids then fly to hedge woundwort, a wildflower, for the rest of the summer, but return to the currants in autumn to lay their eggs. Since the currant crop isn’t affected, action isn’t essential.
Sap-sucking aphids cause the leaves of currant bushes to become distorted, with raised, puckered areas and patches of yellow-green or red.
