Hi all! New member here from zone 5b (near Montreal, Qc) who loves to garden to attract birds... Yet year after year, after year, the many berries my V. creeper produces always abort, after growing much more slowly than what I see in the wild (or just anywhere for that matter), up to the size of about 2 mm only... Planted and otherwise thriving perfectly on a latticework set in a partly shaded spot in the garden (very good sun exposition from dawn to noon). Soil is loamy to rich. Never had that problem in a previous location nearby with the same soil... I am baffled by this issue... GH
