| St Patrick's buds never fully open. They are wrinkled and deep brown at the base. When I remove the petals the core is dead and blackened. I can see no bugs. I am trying to attach a photo. Help anyone? andreark |

| Are you in the UK? Because this problem seems to be going rampant in Nottingham! Florist roses, garden roses, all sorts of HTs are getting this :( To be honest, I was just about to start a topic on this! This same thing happened to my "National Trust" HT :( |
|
| Not exactly UK. I'm in California.... So what is it? andreark |
|
| I hope someone has a answer for this because it's quite puzzling. Have you had hot dry weather, Andrea? |
|
| Thanks Seil. Yes we have had hot dry weather BUT none of my other roses, HTs or Austins, have been afflicted. I hand water the raised bed that St. Patrick is in. (It is raised but built over soil) If I had omitted watering for this plant, would this happen? I water 2 or 3 times each week. So the most this plant, if I missed it, would have gone without water is less than a week. andreark |

| It could be Botrytis Blight (Botrytis cinerea), I have this problem and I am in California. |
|
| Thanks for your answer TT. I looked up Botrytis Cinerea and the sites that had info on it said that there is an accompanying grey mold. I have no mold, the buds just shrivel and die. And the center turns black. andreark |

| Take some to the County Extention office. Let us know when you get an answer. |
|
| Botrytis normally affects the outer petals most. On flowers it produces brown rotten spots, not usually noticeable gray fuzz, I have never seen or heard of the problem you describe on a HT. Some cluster-flowering roses abort some buds for mysterious reasons. The neck tissue turns reddish and then yellow. |
|
| Thanks Michael and Kentucky. I removed all the affected buds. I'll just have to see if it returns. andreark |
