Belle of Woking not blooming
I have 2 Belle of Woking in different areas of my garden for 4 years now. Lots of shoots- no blooms. They are both paired with shrub roses that I planted at the same time as the clematis. The roses have bloomed wonderfully. Soil is probably more acid due to clay, but I have taken most of the clay out and added good soil, compost, and manure. There are 3 other clematis in the same area as these 2 and have never had a problem blooming. I guess what I'm wondering is if Belle of Woking is slow to get started or am I doing something wrong.I would like to see some blooms this year.
