From the attached leaf photos, can you tell us what is wrong with our flowering currant. Its leaves morph into this condition soon after leafing out--all summer.
Is there something we can do to combat this? Thank you.

Expert Response
Currants get aphids very early in the season. The aphid feeding causes the leaves to have a very red color. The red color stays all summer.

Controls are - dormant oil in March.
Summer sprays of Neem oil, insecticidal soap, pyrethrins or spinosad sprays do a good job of controlling the aphids.
Planting a lot of nectar flowers will increase your aphid predator population and reduce the aphids in the general garden area.
