I planted two corkscrew willow cuttings (one golden, one dark, big ones - 6' each, at least) mid to late May. I'd had them in the house since March (got them at a home/garden show) in one gallon water containers. They were doing beautifully. Within a week of planting out, one had turned almost completely black on every stem, and the other was fine. Yesterday when I went to pull up the "dead" one, I saw signs of life, so I cut away all blackened stems and left anything that was still yellow and had green leaves.
I went to check out the other, dark willow, and saw signs of smaller branches on it turning black, so I cut them out as well. It's like the entire branch just turns black all of a sudden. They're also dried out an brittle when this happens.
I've searched on google and I'm not coming up w/ anything solid. Has anyone else experienced this? TIA!
