Answer: Unfortunately, Japanese Beetles love the Rose of Sharon shrub. Other pests include aphids and spider mites. Hand picking the adults or using a botanical alternative can help control those pesky Japanese Beetles. Neem products such as Azatrol or Neem-Away, or Pyola (pyrethrins in canola oil) provide about 3-4 days deterrence of Japanese beetle feeding so repeat applications will be necessary. Be sure to apply according to label directions. Best wishes with your hibiscus.
