How to Get a Winter Blooming Jasmine to Bloom

Plant your winter jasmine in a spot that receives full sun during the winter. Winter jasmine blooms best in full sun and blooms poorly if kept shaded in the winter. Throughout the rest of the year, this plant grows well in full sun or partial shade. To prevent leaf burn, plant your winter jasmine where it will be shaded from intense afternoon sun during the summer.

Amend the soil around your winter jasmine with sand to improve drainage if you have clay soil. Although not picky about soil pH, winter jasmine grows best in well-drained soil. Heavy clay soil makes it difficult for your jasmine to take nutrients up through the roots and soggy clay can lead to root rot.

Train your winter jasmine to grow up a trellis. This isn't a requirement to make it bloom, but it exposes more of the plant to the sun and therefore encourages more blooms along the length of the plant.

Feed your winter jasmine with a low-nitrogen fertilizer when you see buds beginning to form in the winter. Look for numbers on the label that read 4-10-10 or similar readings in which the first number is less than the other two numbers. Nitrogen encourages leaf growth rather than blooms. Too much nitrogen will lead to a lush jasmine, but few or no flowers.

Prune your winter jasmine after the blooms have faded in spring. Trim away any dead or unhealthy branches. Also trim back to control height and shape. Pruning encourages new and fuller growth. This growth will produce blooms the following winter.
