Tiny Pest, Big Problem: Thrips on Roses

Have you noticed rose buds that never seem to open properly? Tiny insects called thrips may be the culprit.

Thrips feed on developing flower buds and petals, causing blooms to appear distorted, discolored, or fail to open altogether. Their damage is often most noticeable in light-colored roses, where petals may show brown edges or streaking.

To help manage thrips, remove and dispose of damaged blooms, keep garden debris cleaned up, and encourage beneficial insects such as lacewings and minute pirate bugs that naturally prey on thrips. If infestations become sever, horticultural oils or insecticidal soaps may provide control when applied according to label directions.

While frustrating, thrips are a common challenge for rose growers during warm weather. Regular monitoring and prompt action can help keep you roses healthy and blooming beautifully throughout the season.
