I had the landscaper change the soil this time and added wood mulch to the bed. The leaves as they came in were fantastic. Gorgeous colors and so full. Then came the first signs of the aphids. My landscaper told me to get some ladybugs in the Spring, which I did. They seemed to do the trick for a while, then, came the bites in the leaves and a return of the aphids (if not in as great abundance). Finally, before my buds even opened it looked as if they had been burned at the edges. When they opened, the black peppered the edges of the petals.
I’m not a great gardener but I love these roses and had real hopes for them this season.
A. From your description it sounds like Western flower thrips damage. They attack the petals of flowers before they open and cause browning and wilting of flower buds. You can apply Spinosad for some organic control but you will have to apply it multiple times about a week apart to get any kind of control.
Orthene sprays will work to some degree as well.
Another product to try is an insecticide that contains imidacloprid in the ingredients. One such product is at Viragrow and probably some nurseries as well.
