Hello,

I have several burgandy velvet rose plants in my rose beds which have a
peculiar problem.

They produce a dozen roses in one go. But they have only a few green
leaves

Hi Bob. Is it possible that a fungal disease such as black spot is
defoliating your roses? Dead give-away: there will be leaves on the
ground. Let us know. And also, what is a "burgundy velvet" rose? Sounds
pretty.
