How to Care for Jasmine Shrubs

Overview

The star jasmine, jasminum multiflorum, is an evergreen shrub native to parts of India. The plant produces white flower clusters that are fragrant and open their blooms in the evening. Star jasmine is hardy enough to plant in USDA growing zones 9 through 11 where there is a low risk of freezing temperatures. The star jasmine plant grows to a height of 5 to 10 feet and must be pruned each year to maintain a shrub appearance.

Step 1

Plant the jasmine shrubs in well-draining soil with full sunlight from the south or west. Test the soil pH to verify it is between 7.0 and 7.5. Work limestone into the soil to raise the pH number or ground rock sulfur to lower the pH number.

Step 2

Dig a hole that is the same depth and slightly wider than the container the plant came in. Work an even quantity of organic compost into the removed soil. Place the shrub in the hole, and gently pack the soil around the root ball. Water the jasmine shrub generously after planting to stimulate root growth.

Step 3

Water the shrub during the summer growing season to soak the soil to a depth of 10 to 14 inches. Apply water when the soil is dry 1 to 2 inches below ground level. Monitor the soil moisture level as additional water may be required during the hot summer months and during periods of drought.

Step 4

Mist the jasmine shrub with water several times a week to keep the humidity level high around the plant.

Step 5

Fertilize the jasmine shrub every two weeks from late spring to late summer with a balanced water soluble fertilizer that is acidic. Use warm water when applying the fertilizer to prevent plant shock. Do not over fertilize or use a high nitrogen fertilizer as this will produce thick foliage but limit flower production.

Step 6

Monitor the shrub for an infestation of aphid or scale insects. Remove the insects with a sharp stream of water. Treat the shrub with insecticidal soap to keep the insects off the plant when they are in the crawler stage. Prevent insect infestations by applying dormant oil during the spring season.

Step 7

Prune the jasmine plant in early spring or late fall to maintain a shrub shape. The plant will vine out when left to grow naturally. Prune to remove dead and damaged branches anytime during the growing season.

Step 8

Propagate jasmine shrubs by taking softwood stem cuttings in late spring. Cut 6- to 8-inch sections from new growth that is flexible yet snaps easily in half. Dip the cut end into rooting hormone, and stick it into a rooting tray filled with moist rooting medium.
