Weeping cherry within the 50' zone of a walnut tree
I found a list compiled from Ohio State University saying a list of fruit trees that can be grown near Black Walnut trees. (Surprised me I thought no fruit baring trees went near walnut trees) Cherry was on the list of things you can plant near a walnut tree. I am considering 50 foot from trunk...not the drip line for the planting.
After researching I don't feel I should have any trouble at all...surly weeping cherry falls into the same category as a cherry fruit baring tree in being tolerant of juglone. Even though it is considered an ornamental tree.
