Indoor Jasmine Care: White, Fragrant Flowers

Few plants perfume a home or balcony like jasmine. Its small, star-shaped white flowers give off a sweet, unmistakable scent, especially at dusk. Several species go by the name "jasmine": the classic Jasminum officinale, Jasminum polyanthum (very common in pots), and star jasmine (Trachelospermum). They all share the same basic care.

Light: essential for flowering

Jasmine needs lots of light to bloom:

Ideal: full sun or very bright light; a little gentle morning sun is perfect.
Tolerates: strong indirect light next to a south- or east-facing window.
Avoid: dim corners, where it grows but won't flower.

If your jasmine is leafy but flowerless, it most likely needs more light. To get a better feel for how much light each spot in your home gets, our indoor plant light guide will help.

A support to climb

Jasmine is a climber: it needs something to cling to. Put a trellis, hoop or some canes in the pot and train the stems as they grow. This keeps it tidy, encourages more abundant flowering and improves airflow through the plant.

Watering

Keep the soil lightly moist during the growing season, without waterlogging:

In spring and summer, water when the top inch is dry.
In winter, water less, but don't let the rootball dry out completely.
Always empty the saucer to keep the roots from rotting.

Humidity and temperature

It appreciates moderate-to-high humidity. If heating dries the air out, group plants together or use a humidifier. Most indoor jasmines prefer temperatures between 60 and 75 °F.

Key trick: many jasmines, like polyanthum, need a few weeks of cool autumn nights (50-60 °F) to set flower buds. Without that drop in temperature, they struggle to bloom in winter.

Feeding

In spring and summer, feed every 2-3 weeks with a potassium-rich fertilizer to encourage flowering. Stop feeding in winter, when the plant rests.

Pruning

The best time to prune is right after flowering. Trim the stems to shape the plant, remove dead growth and encourage new shoots, which will carry next season's flowers. Prune at the wrong time and you can lose the blooms.

Soil and repotting

Use a fertile, free-draining mix. Repot every 1-2 years in spring into a slightly larger pot when you see roots coming out of the drainage holes.

How to propagate it

Jasmine roots from cuttings in spring or summer:

Cut a stem tip about 4 inches long, just below a node.
Strip the lower leaves and keep two or three at the top.
Plant it in a moist mix and keep it warm, with indirect light and good humidity (you can cover it with a clear bag).
In a few weeks it will root and you can move it to its final pot.

This way you can have several plants for different spots, or give one to anyone who loves that scent.

Common problems

No flowers: not enough light, no cool autumn spell, or too much nitrogen.
Yellow leaves: usually overwatering or hard, limy water.
Sticky leaves or cottony tufts: aphids or mealybugs; check the undersides.
Dry tips: air that's too dry.

Is it toxic?

True jasmine (Jasminum) is non-toxic to dogs and cats, making it a safe choice. A word of caution: "night-blooming jasmine" (Cestrum nocturnum) is a different plant and is toxic, so make sure of the species you're buying.

With plenty of light, a good support and a cool autumn rest, your jasmine will fill the home with white flowers and that unmistakable perfume.
