Your least-affected roses ... Japanese beetles, thrips ....?.
We have a mini-drought here, trees are wilted, temp. 85 to 95 F. Thrips are gone, but the Japanese Beetle go after the lush and watered roses, they leave my never-watered Knockouts & FlowerCarpet alone.
My neighbor next to the creek and a lake have zero beetles on her roses. There are a few of my roses that JB don't care for: William Shakespeare 2000, Wise Portia, Annie L. McDowell, Marie Pavie, Mary Magdalene ... never find a bug on these. Sonia Rykiel, found only one JB this year. These have tight petals.
But JB really attack Firefighter, Sweet Promise, Liv Tyler, Frederic Mistral, Francis Blaise, Pink Peace with gap in between petals for them to hide. I pick most of my roses to give to neighbors, before JB get to them.
Which one of your roses insects don't care for? Thanks in advance.
