Night-blooming jasmine, also known as Cestrum nocturnum or night jessamine, is a woody, evergreen shrub that is prized for its highly fragrant, white, trumpet-shaped flowers which, as the name suggests, open only at night. Growing up to 12 feet tall with a 4-foot spread, this delightfully fragrant shrub is an attractive and must-have plant for night-blooming or fragrance gardens.
Select a full sun planting location for your night-blooming jasmine that receives six to eight hours of direct sunlight each day. Choose a planting location that also offers sandy, well-drained soil or amend your soil by tilling coarse builder's sand into the top 15 to 20 cm (6 to 8 inches) of soil to improve drainage.
Plant your night-blooming jasmine in its prepared planting location. For best results, plant your night-blooming jasmine at the same level it was planted in its nursery container. Pack down the surface of the soil after planting and water generously to help settle the soil.
Provide regular irrigation for your night-blooming jasmine to maintain consistently moist soil. Water your night-blooming jasmine in the morning or early afternoon to ensure that the foliage of your plant is not still wet at nightfall.
Fertilise your night-blooming jasmine with a slow-release granulated fertiliser that has been specially formulated for flowering plants. Apply the fertiliser once a month according to the application directions on the product label.
Prune your night-blooming jasmine, as needed, to maintain the desired size and shape. Remove discoloured, diseased or dead foliage, as needed, to keep your night-blooming jasmine looking its best. Use only sharpened and sterilised pruning shears to prevent the spread of plant diseases and minimise the pruning stress to your night-blooming jasmine plant.
Night-blooming jasmine can also be grown indoors in a container. Plant your night-blooming jasmine in a container that is large enough to comfortably house its roots. Use a well-draining growing medium of equal parts potting compost, peat moss and coarse builder's sand. Fertilise indoor night-blooming jasmine every two weeks using a water soluble houseplant fertiliser.
Never allow your night-blooming jasmine to become waterlogged. Standing water can cause undesirable leaf drop and root rot.
