Night-blooming jasmine is an evergreen shrub that grows 6 to 10 feet high and spreads to a bush about 6 feet wide. Night-blooming jasmine is only hardy outdoors in USDA zones 8 through 11. In colder areas, grow night-blooming jasmine as a potted plant and bring it indoors for winter. Night-blooming jasmine blooms after dark with sweet, fragrant blossoms.
Choose a site for night-blooming jasmine that is in full sun to partial shade. The soil should be damp and consistently moist for the most blooms.
Prepare the soil. Add 2 to 4 inches of peat moss and 2 inches of compost to the surface of the soil. Dig it into the surface by turning the peat moss over with a spade. Rake the area smooth.
Plant bushes at least 4 to 6 feet away from competing vegetation, such as small shrubs or trees. Dig a hole that is twice as large as the night-blooming jasmine's root ball. Mix the soil you removed from the hole with at least one 5-gallon bucket of compost. Add ¼ cup of fertilizer specially formulated for flowers to the soil at the bottom of the planting hole. Scratch it into the soil with a garden claw. Add some improved soil to the bottom of the hole and set the roots of the transplant on top of it. Back fill with the improved soil, firming it gently with your hands as you fill the hole. Firm the surface of the soil with your foot.
Create a ridge of soil around the outside of the planting hole using your hands. This will catch and direct rain water down to the roots.
Water the plant well. Place a hose set at a slow trickle near the base of the bush for 30 to 60 minutes.
Mulch the area with a 4-to-6 inch layer of shredded bark or wood chips.
Feed night-blooming jasmine in early spring by spreading granulated fertilizer around the base of the plant. Pull back the mulch and spread fertilizer specially formulated for flowers in an 8-inch circle around the base of the bush. Replace the mulch.
Grow potted, night-blooming jasmine in a 16-inch clay or ceramic pot using regular indoor potting soil. Place outdoors in full sun during frost-free weather. Bring the plant indoors before the first freeze in autumn. Place the plant in a south-facing window in normal room temperatures. Water when the surface of the soil begins to feel dry. Do not allow the soil in the pot to dry out, or your night-blooming jasmine will not survive.
