Asiatic jasmine, known botanically as trachelospermum asiaticum and more commonly as dwarf jasmine, is a sun-loving, flowering perennial ground cover with a vining growth habit. It flowers in late spring, summer and fall and, being a tender semi-tropical plant, is winter hardy only in USDA Zones 7B through 10. It thrives in moist, nutrient-rich soil and is an aggressive spreader, so pruning to control sprawl is the most common pruning required.
Give your Asiatic jasmine a quick inspection each time that you water, looking for browning foliage, dead or damaged stems or leaves and signs of pests or disease. Cut away any damage that you find back to the point of healthy wood and discard the clippings.
Prune your Asiatic jasmine once or twice per year to control the sprawl of the vines from creeping into and interfering with other plantings, paths, lawn or hardscapes. Use secateurs or shears to make blunt cuts on either the woody or green herbaceous growth as needed and collect and discard the clippings.
Hard prune your Asiatic jasmine once every 3 to 5 years to rejuvenate defoliated woody sections and trigger new green growth in bare spots. Remove up to one-third of the jasmine plant's woody stems and vines in each session and either compost or discard in the trash.
Water your Asiatic jasmine deeply after any significant annual or hard pruning to reduce the shock to the plant by removing drought stress and spur production of new growth.
