A query for Dan Gill: What’s the easiest way to manage thrips on roses?- Marilyn

Reply: Thrips are small bugs that assault rose flowers by coming into and infesting the buds whereas they’re nonetheless closed. Infested buds could fail to open or solely open partially. Flowers that do open exhibit tan, burned edges to the petals, as if the flowers are outdated proper after they open. In the event you look into the flower and separate the petals, it’s best to see the small thrips.

Roses that produce double flowers with many petals are extra vulnerable to thrips than roses that produce single flowers with fewer petals.

Though they don’t harm the bush itself, it’s a disgrace to see flowers ruined. The spring/early summer season blooming is when thrips typically assault. An natural choice for management is spinosad (Bonide Captain Jack’s Deadbug Brew, Ferti-lome Borer, Bagworm, Tent Caterpillar and Leafminer Spray, Inexperienced Gentle Spinosad Garden and Backyard Spray).

Sooner or later, start spraying as quickly as you see the rose buds forming.
