The large and extremely heavy flower buds on my Auguste Renoir rose never open. I have tried cutting them and bringing them indoors before the buds turn brown and fall off the bush. This does not help. I live in Southern California in the San Gabriel Mountain foothills. The summer days are warm and the nights arecool. Does anyone have suggestions or information about this problem?

I have the same problem, have read the same comment from someone in Chicago, and I am in the Seattle area. Do we see a pattern here? Is there anything that can be done about balling?

I just dug up my Auguste Renoir because of the same problem. I was sad to see it go because it was a vigorous plant and a prolific bloomer, often carrying 50 blooms at a time, but only a fraction of them would open. I think the cooler climate of Southern California is part of the problem.

I am giving Auguste Renoir one more season to earn his keep. The buds are large and should open in 2 days. Someone suggested thrips may be Auguste Renoirs problem but I will check next week.

When my roses behave that way it is because the blossoms are infested by thrips. The thrips are very tiny (like specks of black pepper). They damage the rosebud so that it does not expand.

That is very helpful to know. I have been struggling with thrips this season, and have hesitated to spray the blooms themselves to keep down the thrips because I am worried about the serious honeybee population decline. Does anyone know if spraying actual buds and blooms with Rose Defense or some such threatens honeybees?

I still have Auguste Renoir and it is full of flower that are not open yet. It is located close to three other rose bushes that have flowers that always open. Do thrips spread to adjacent shrubs? I will keep a close watch as Auguste may finally be replaced this January.

I have had Auguste Renoir for 3 years and it has usually balled without opening in the hot San Fernando Valley of Los Angeles, I first thought that the sprinklers were hitting the roses but it is tall enough not to be wet. The rose will be removed as it is painful to view all those balled rose flowers. Guy de Maupaussant is wonderful as so is Yves Piaget both Romantica roses.
