Chinese redbud trees
I bought 6 trees through the post 2 years ago and duly planted them along side my garden wall approx 3 feet apart with a view to them developing a screen ie for privacy. They have grown well (from 6 inch cuttings to 5ft bush type structures) but are yet to produce any of their famous bright purple blossom. Does anyone have any experience of growing them? I would be most grateful for any advice to encourage this years blossom.
