Can Madrona be used Outside?
We have Madrona Trees on our property in the San Juan Islands, WA. One large branch fell and I used it for decoration indoors. When I went to get more branches, however, the entire thing had turned black. We were hoping to use a branch for a porch railing. Did it turn black because it was out in the elements (rain) or was it some kind of fungus? Wondering if I cut a healthy branch off and use it for a porch railing if it will eventually turn black?
Yes turning black is part of the process of decomposition.
So for an outdoor railing you would have to use a dry piece with an outdoor varathane to protect it.
