Came dieback on young Tea/Noisette bands
I've been struggling with a few roses lately, and had more than one kick the bucket. Specifically Tea/Noisette type roses. The bands start dying from the top of a cane, and then it slowly creeps down the cane until all of the leaves wilt, drop, and the plant is a bundle of sticks. I haven't the slightest idea why this has happening, and they are being amply watered and in good soil. So far I've lost:
Jeanne D'Arc (5 gallon)
Souv. De Mme Leonnie de Viennot
And Souv. D'Elise Vardon and Louis Phillipe (1 gallon) are on their way out. Considering they weathered the winter just fine, this is baffling to me. Any thoughts? I must be missing something. I just had a 1 gallon of Mrs. B R Cant go toe up, while the one next to her which is smaller, is just fine.
