I'm confused. Why would one wait until bud break to prune the roots? It seems like any substantial root prune should be accompanied by an equally substantial top prunning, which would eliminate most of the flower buds anyway. My intuition tells me that late fall, after the foliage has gone dormant but while the soil is still warm enough to promote root development, would be a suitable if not ideal time to work with quince.
