How to Manage a Rose of Sharon to Keep Bugs Off

The Rose of Sharon, or hibiscus, produces beautiful flowers that add a tropical touch to a garden. Its sturdy foliage also makes for a visually arresting hedge that's sure to impress neighbors. However, the plant may also draw unwanted attention from bugs. Luckily, the bugs most attracted to the Rose of Sharon—such as aphids, Japanese beetles, or whiteflies—can be easily eliminated from your garden.

Protect Against Aphids

Step 1

Release ladybugs into your garden. Ladybugs nest in the Rose of Sharon and eat aphids.

Step 2

Examine the plant one week after releasing ladybugs. If the ladybugs have gone, but the aphids are still present, begin spraying.

Step 3

Mix hot water and dish soap in a spray bottle. Avoid lemon-scented soaps, as the acidity could harm the foliage. Spray the top and underside of leaves, completely coating leaves. Spray daily or every other day.

Step 4

After a week, check again for aphids. If the aphids are still present, switch to insecticidal soap.

Step 5

Spray with insecticidal soap according to the manufacturer's directions.

Protect Against Beetles or Whiteflies

Step 1

Pick off any beetles or whiteflies and discard in a bucket of hot water.

Step 2

Mix hot water and dish soap in a spray bottle. Spray top and underside of leaves, completely coating leaves. Spray daily or every other day.

Step 3

After a week, check plant for bugs. If the beetles or whiteflies are still present, switch to insecticidal soap.

Step 4

Spray with insecticidal soap according to the manufacturer's directions.
