About Arabian Jasmine

Jasminum sambac · also called Arabian Jasmine, Sampaguita · flowering

Arabian jasmine is a tender evergreen scrambling shrub or short climber grown for its waxy white, powerfully fragrant flowers that open in the evening and are used in garlands, teas and perfumes. The national flower of the Philippines and Indonesia, it loves heat and humidity and is best grown in containers and overwintered indoors in cool climates.

Plant type: flowering

Watch for — Sparse flowering: Too little light or cool conditions limit blooms. Give maximum sun and warmth, feed with high-potash fertiliser, and prune lightly after each flush to stimulate new flowering wood.

The reasons arabian jasmine isn't blooming

Almost every non-blooming arabian jasmine traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding arabian jasmine a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get arabian jasmine to flower

Maximise sun. Give arabian jasmine the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for arabian jasmine and get the feeding right with the arabian jasmine fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Arabian Jasmine flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full arabian jasmine care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Arabian Jasmine blooming — frequently asked questions

Why won't my arabian jasmine flower?

Arabian Jasmine blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
