The Jasmine plant (Jasminum) is a vine that can produce sweet-smelling flowers, but not all varieties have a fragrance. Jasmine is common in tropical and subtropical climates. "Winter" jasmine (Jasinimum nudiflorum) can grow in colder environments. Unlike other flowering vines, Jasmine plants are not invasive vines, but some pruning is necessary to keep them nicely shaped and under control.
Wait until the flowers have stopped blooming. This varies among Jasmine varieties, but generally the flowers stop blooming in the fall. Use clippers to thin out the plant. You do not have to cut Jasmine back to the ground. Instead, thin out the growth by clipping several vines in an overcrowded area. In addition, cut back the overall height by several feet if it is getting too high.
Prune Jasmine vines, such as the common white Jasmine (Jasminum officinale), often if you are trying to use it as a bush. You do not need to wait until it is done blooming to prune.
Cut a Jasmine plant back to ground after flowering only if the plant becomes infested with spider mites. Pick up all the cuttings and throw them out. After cutting back, fertilize the plant with a balanced fertilizer labeled 10-10-10.
