| My friend has a climbing rose that they pruned heavily last year, and this year the new growth looks very strange. Many of the leaves look ruched and the color is a bit strange. We've had a lot of extra rain and unusual weather, so I'm not sure if it's just that or if something else is going on. (I'm sorry for the poor quality pictures.) Thanks for your help! |

| Can you get more pictures? A close up of the leaves and a side view of the canes would help. |

| I'm finding a similar ruched look in some of the leaves on a couple of my roses this year. I'm in the same zone and have also had strange/rainy weather (southern Ontario, Canada). I don't have any pictures but will take some next time the opportunity presents itself. I'd like to know as well... I am wondering about RRD. (sorry I'm not more helpful) |

| Other than color, the leaves look fine to me. It looks like the red of new growth fading to the chartreuse of chlorosis. Try getting some granular Ironite and sprinkling it around the roses showing this. I saw this a bit on some of my roses with heavy Multiflora background -- Polyanthas and Hybrid Musks, 'Bleu Magenta' and the related 'Purple Skyliner' -- soon after the first set of leaves in Spring, and also following any bouts of heavy rain. It's as though the leaves are forming faster than the roots can suck up iron to get them fully green. I got a big bag of Ironite for lawns and kept it on-hand for whenever I noticed it happen again. :-) ~Christopher |

| It's extreme iron deficiency chlorosis where the plant is unable to produce chlorophyll at all. Causes could include high (alkaline) PH, waterlogging, or if the pattern of growth is abnormal, herbicide damage or rose rosette disease. Please provide clear images from the side showing the thorns and how the stems branch--the upper foot or two of the affected stems. Tell us anything that might bear on the possible causes listed above. (Water, use of lime, possible herbicide exposure--even a stray droplet). |
