You need to give your plants a little more time, if you haven't pruned your plants since January you should be getting some blooms pretty soon. It takes a little time for the flower buds to develop after the last stop ( 8-9 weeks for singles etc) and as your plants had also to develop the foliage this can be extended somewhat.

Patience is a virtue......... and it will be worth it in th end.

Let us know how you get on.
