Summer jasmine is best pruned just after flowering, in late summer or early autumn. Winter jasmine should be pruned in spring, immediately after flowering. On both types you can cut back flowered stems to a strong sideshoot and thin out crowded, crossing or misplaced branches. You should also remove any weak or thin stems. Overgrown vines can be cut back to about 2 feet from the ground.
