I'm trying to find out why/what these orange balls are on the end of my rose bushes. They appear to show up after a bloom has completed it's cycle. It doesn't happen to every bloom. I get several throughout the bush and the balls don't ever fall off on their own once they have arrived. My rose bushes are what we like to call "antique wild". The original stems are over 50 years old but they constantly shoot up new growth all around their feet.
I'm not sure if I should be pruning these balls off, is it a disease or is it a natural occurance for some species??
Please help with the orange balls.
