Hi,

I've got an odd problem with several of my dark red roses - they produce
very
few leaves - but plenty of blooms. Sometimes there are no leaves on the
cane. They are BlackBoy variants - taken by cutting. Not much of a scent.
Not a climber.
Multiple petal diamond shaped rose flowers. Beautiful roses.

What can I do to encourage it to have more leaves?

Could it be due to the fact that they were cuttings which I placed into the
ground after about 1 year in a pot?

Or perhaps its just a case of black spot?
