A well-fertilised healthy jasmine plant gives off a strong fragrance that will fill the area around it with its perfume. The type of fertiliser depends on whether it is container grown, the soil type, the species or if it is growing naturally in the soil. Several plants bear the name jasmine in their title, but there are only two species of the fragrant flower: the poet's jasmine from the Himalayas of China, and the royal jasmine with the highest scented flowers. Keep your jasmine fertilised and enjoy the beauty of the blossoms and their delicious fragrance.
Add a fertiliser high in phosphorus to container-grown jasmine plants every two weeks during the spring and summer to encourage flower production. Use a water-based solution of the fertiliser in place of the regular water, following the directions on the packaging. Replace the soil every two or three years to prevent a build-up of salts from the fertilisers.
Add little to no fertiliser to garden grown jasmine plants where the soil is amended every year with organic matter as the plant will subtract enough nourishment from healthy soil. Add a balanced fertiliser every two weeks in the spring and summer only if the leaves are yellowing or the plant seems stunted in its growth.
Fertilise natural or wild plants of jasmine by mulching around their base with a mulch of compost in the spring and summer. Add a slow-release balanced fertiliser to the mulch if the plant seems to be lacking in fragrance or if the soil is low in organic matter.
Species of Jasmine
Feed the higher scented royal jasmine with more fertiliser than the poet's jasmine as it has more flowers and larger flowers. Use the high phosphorus fertiliser every week in the spring when the buds are in full development.
