The recent news about juglone and black walnut trees coming of Washington State University Extension is that there is no conclusive, science-based evidence confirming juglone as the cause for the poor growth of plants growing near black walnut trees., https://research.libraries.wsu.edu/xmlui/bitstream/handle/2376/14212/FS325E.pdf?sequence=1&isAll...
With that being said, I checked to see if weigela is listed as a plant sensitive to juglone. I did not find it on the list. But, the farther away you can plant it from the tree the better. Weigela likes full sun and in general, shrubs do not grow well if they have to compete with tree roots for water and nutrients.
