roses dying

Question

Why do my roses all look as if they are half dead when they open?

Answer 1

You could have either a thrips problem or they are not getting enough water for the temperatures you are having. A systemic insecticide is needed to really get after the thrips, so I would give them a treatment of Bayer Tree and Shrub Granules and water it in well. The systemic in the Bayer product will move up through the roots and into the roses natural juices to get after the thrips.
