Got any pictures??

It sounds like a fungus of some kind, but I searched for diseases of cenizos and didn't find anything in the way of susceptibility to fungus diseases; just cotton root rot. I think the symptoms in that case would be wilting.

Quote from internet:

" ...to thrive in a landscape, it must have full sun and very well-drained alkaline soil. Although watering in dry summer months will make it grow faster, overwatering or poor drainage will quickly kill it, and shade will promote leggy growth and less flowering. In areas of high rainfall or poorly drained soil, cenizos should be planted in raised beds. If they are planted in acid soils, dolomitic limestone should be added. Fertilizing is unnecessary. Cenizos are not susceptible to pests or diseases other than cotton root rot, which well-drained soil will discourage."

I've noticed some yellowing leaves with little black spots from time to time on my cenizos that were not in full sun. They lost leaves but didn't die.

Hopefully, someone else will see this and respond. And yes as Mara says, pictures of the problem would be helpful.

Thank you so much for the replies. I am uploading two pictures, for some reason they upload sideways. Hopefully this will help.

Thanks again!

I would show your pictures to the master gardeners at Buchanan's or Cornelius.

These plants like to dry out and they have not had rear chance this year. Mine are not very happy either.

I agree, I'm thinking maybe just too much rain. It likes to be fairly well-drained, I believe.
