Hi all! New member here from zone 5b (near Montreal, Qc) who loves to garden to attract birds... 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)... for over 23 years now... Soil is loamy to rich. Never had that problem in a previous location where we lived nearby, with same soil type... I am baffled by this issue... GH
