Answer: Rosa Mutabilis should be pruned in early spring, just as the buds begin to swell. It sounds as though the sap is already flowing and that's why the cuts are weeping. Although it looks alarming, it won't hurt your plant. Eventually the sap will harden and seal the cuts. I've had a similar experience when pruning my grapevines. I thought it would never stop weeping, but eventually it did - no harm done. To avoid this in the future, try to prune in January when the rose is still dormant.
