Hi All, I planted an autumn clematis last summer, and didn't get a bloom last year. This year it's about 7' tall and the top 2' is loaded with white blooms, but they're tiny! Not even an inch across. I did minimal watering this year, but the plant never wilted. About 4 - 6 weeks ago many of the lower leaves did turn yellow and die. I added peat and manure to the hole when I planted, but no fertilizer this year. The plant was one of those boxes they sell at walmart - Better Home & Garden brand, maybe. Any ideas on anything I did wrong? Or does this type of clematis just have smaller blooms? Thanks! Barb
