Yellow leaves with black spots on bottom branches

14 years ago

Argh! My mini roses were doing so well this summer, growing like crazy and blooming like nobody's business. Now I see that the middle mini-bush has developed yellow leaves with black spots at the bottom branches, although it's blooming and blooming. What is this??? What can I do to help my poor bush? Thank you.

You do not have the area you live nor the zone you are in but it sounds like your rose has black spot. You can treat it with a fungicide such as Bayer or Ortho for fungus and disease control. Try not to use Bayer 3 in 1 or an insecticide/disease control combos spray. Below is a link that may help you.

I also think you may have blackspot. In addition to rosenspots suggestions, I suggest picking off the blackspotted leaves (both yellow and green) as much as possible. Routinely looking for and picking off damaged/diseased leaves has helped limit blackspot on my rose bushes. Of course, a lot will depend on the number of rose bushes and the time you have available.
