In 2018 I collected a Red Cedar yamadori in eastern NC that had been growing atop of a concrete slab. I am aware that eastern red cedar is not your typical bonsai material for multiple reasons. This tree however does have great movement on lower portion of the thunk. Essentially the tree could be collected without having to use any tools. The collection location was also less than 150 yards from my home so I went for it. Fast forward to spring 2019 and the tree is showing tons of new growth as well as cedar apple rust on about 2/3 of the branches. The tree branching is very spacer so pruning off the infected areas would be a death sentence. My neighbor has a apple tree less than 100 yards from my bonsai collection, collected red cedar and several wild red cedar trees are growing in the area. This makes me believe that cedar apple rust disease is here to stay. While checking the tree this morning 3/2/19 the rust has grown. Attached are photos of the red cedar.
My question’s are:
- Can cedar apple rust effect other species of Junipers or just red cedar and apple trees?
- My entire bonsai collection is located within this mess. I have several species of Junipers, 4 black dragon cryptomeria, 2 Hinoki Cypress, spruce and JBP’s. Do these trees have the possibility of becoming infected?
- What are some possible options for the infected red cedar? replant at original collection sight, trunk chop and graft, keep in grow box, total removal…anything ?
Thanks in advance and I look forward to your advice.
