Climbing Rose Blooms Problems

Filed Under: Insects, Insects · Keywords: Hi, Gardenality, Insects, Soil, Seed, Rose, Clematis, Zone 8, May, Upload, Image, Question, About · 1093 Views
It seems we have a lot of predators and and not many beneficial insects to keep them in check. I really don't like insecticides,
The climbing rose in question if full of buds and blooming, but quickly die, turning a darker red and the petals seem to melt into itself.
Looking through the petals don't see any thrips and the leaves seem okay, so I'm thinking maybe fungal in the soil?
I'll upload some pictures, thanks for your help!)

Answer #1 · Maple Tree's Answer · This does appear to be damage from thrip. It looks as though they may be entering the flowers after opening and not entering the newly formed buds. Many times buds are damaged prior to opening causing the flower not to develop fully. Thrips can be very hard at times to see as they make their way deep into the flower. Their damage can be seen a lot easier on lighter colored flowers but on the dark red flowers the petal edges will become darker red along with the petals shriveling up. The plant itself looks extremly healthy. I can see no insect, fungus, or mildew damage to leaves or discoloration and spotting which would indicate both a fungal disease or nutrient deficiency. If you want to try an insecticide for your rose you can use Malathion or Liquid Sevin. I don't see any foliage damage so I would spray only the rose buds and not the whole plant keeping most beneficial insects safe from being killed on contact. Be sure to apply as per product instructions and noted intervals. You can also use Neem oil as it works as both a fungicide and insecticide and won't harm the beneficial insects as they do not eat any of the plants parts. I believe within a week or two you should see a difference in the new flowers apperance.
