The jasmine plant produces vines covered in lush foliage and attractive flowers. The vines can reach up to 10 feet in length, though some varieties have a more bushy growth habit than others. While it’s prized for its aroma, not all jasmines produce fragrance. Both evergreen and deciduous jasmine varieties occur, and all require similar care.
Site and Soil
Jasmine thrives in full sun conditions, but can also be planted in an area that receives some afternoon shade if full sun is unavailable. Plant it near doorways or patios where you can enjoy its appearance and fragrance. An area near a brick or stone wall reflects warmth back onto the plant, which helps the jasmine remain healthy and aids growth. The vines grow well in any well-drained garden soil, but working compost into the soil prior to planting can help improve drainage in heavier soils.
The vines require moderate amounts of water to thrive, usually supplied by natural rainfall or once weekly irrigation. Make the most of each watering by irrigating at the base of the plant so the moisture seeps into the soil instead of evaporating away. Water in the morning to help prevent further evaporation. Morning watering also ensures the foliage dries completely before cooler night time temperatures, which helps prevent mildew and other fungal problems. A 1 or 2-inch mulch covering on the soil around the plant helps the ground retain moisture.
A jasmine vine can be trained to climb a trellis or to grow as a bushy plant. For a trellis, tie the vines loosely to the support every 8 to 10 inches along their leaf. Jasmine will eventually climb the trellis on its own, but it cannot cling and climb to masonry or other flat surfaces. For bushier growth, skip the trellis and allow the plant to fold onto itself. The vines can grow several feet high without support before they fold over, which gives them a bushy appearance instead of a sprawling habit.
Climbing growth requires minimal pruning. Pinching off the vine tips helps encourage lateral growth and controls height, and all plants must have disease and damaged vines and foliage removed as needed. Jasmine grown as a bush requires more frequent pruning to maintain its shape and size. Trim bush jasmine after flowering and remove up to one-third of the plant as you shape it into the desired size and hedge form. If insects such as mites heavily invest a jasmine plant, cut the entire plant back to the ground after blooming. It will regrow by the following summer.
