How to Cultivate a Jasmine Plant Indoors

Jasmine has mesmerized people for millennia with its enchanting fragrance. This romantic aroma is a key ingredient in fragrances like the iconic Chanel No. 5, and can even be added to bathwater for a soothing, stress-relieving experience. Since the 5th century, jasmine flowers have been used to scent tea and have found their way into desserts, bringing a unique floral touch. You can also invite the delightful scent of jasmine into your home by growing it as a houseplant. Below, you'll find all the essential tips for successfully growing and caring for jasmine indoors.

Different Varieties of Jasmine Plants

There are numerous species of jasmine, as well as other plants that carry the 'jasmine' name—such as star jasmine (Trachelospermum jasminoides)—some of which are poisonous. If you want to grow a jasmine plant indoors, it's important to choose the right variety for your needs.

Popular Jasmine Varieties

For use in perfumes and teas, two primary species are utilized: the well-known common jasmine (Jasminum officinale) is one, and it can be successfully grown indoors.

Arabian Jasmine Variety

Arabian jasmine (Jasminum sambac) is another indoor-friendly variety that is widely used in teas and perfumes. It is a vigorous climbing shrub that grows quickly.

Pink Jasmine Variety

A third variety, pink jasmine (Jasminum polyanthum), is frequently cultivated indoors for its strong fragrance and pinkish flower buds. All Jasminum species are safe for pets, including dogs and cats.

The growth pattern of jasmine plants varies between species. Both common jasmine and pink jasmine grow as vines, often sold in florist shops trained to small trellises. They also thrive in hanging baskets, where their vines can cascade beautifully. Arabian jasmine, on the other hand, grows as a spreading shrub but can be trained to climb a trellis as well.

Jasmine Plant Care Guide

Jasmine plants are relatively easy to care for, but they do need specific conditions to thrive and produce abundant blooms. They grow quickly, so occasional pruning is necessary. The ideal time to prune is right after the plant finishes flowering to avoid cutting off any developing buds. Follow these tips for a healthy, thriving jasmine plant.

Watering Requirements

Jasmine plants are sensitive to dry soil but do not fare well in overly wet soil either. Keep the soil evenly moist by letting the top half-inch dry out between waterings. During the fall and winter months, reduce watering as the plant's growth slows.

Soil Requirements

Jasmine plants need a well-draining, airy soil mix to keep their roots healthy while retaining moisture. A mixture of bark, peat, or perlite offers a good balance of water retention and drainage. Repot plants in spring, trimming the roots as needed.

Light Requirements

Jasmine requires at least six hours of bright light each day to flourish indoors. Indirect, but bright light is optimal, such as near a north or east-facing window. In summer, you can gradually acclimate the plant by moving it outdoors, slowly increasing its exposure to sunlight.

Temperature & Humidity Preferences

Jasmine plants prefer cooler temperatures, thriving in a range of 60° to 75° Fahrenheit. Cooler temperatures are especially crucial in early fall for proper flower bud formation (discussed in more detail below). Jasmine is also sensitive to dry air, so avoid placing it near heat sources like radiators or air vents. To boost humidity, consider using a humidifier or placing plant pots on trays filled with gravel or pebbles and water. Ensure the water level is below the stones to prevent the soil from sitting in water.

Fertilization Needs

Feed your jasmine plants every two to four weeks throughout the growing season, from spring to mid-summer, using a water-soluble houseplant fertilizer diluted to half the recommended strength. Avoid fertilizing during fall and winter when the plant's growth slows down.

How to Encourage Indoor Jasmine Blooms

Common and pink jasmine require a rest period to bloom indoors. To trigger this, simulate autumn conditions during fall and early winter. Provide plenty of bright sunlight during the day, followed by cool, dark nights. These plants need adequate indirect light during the day to form flower buds but must experience total darkness at night. They also prefer cooler temperatures between 50° and 60°F and reduced watering during their dormancy. Place them in a cool, well-lit room where artificial light is minimal at night.

Jasmine plants grow quickly, so regular pruning is essential to manage their size, particularly indoors. However, it is important to avoid cutting at the wrong time to prevent removing developing flower buds. For optimal results, prune the plant immediately after flowering to reduce its size, removing up to one-third of the plant's growth. In spring, once the plant resumes active growth, pinch back the tips of stems to encourage lateral branching. After this trimming, thin out 10 to 20 percent of the new growth to keep the size under control and ensure continued blooming.

Jasminum sambac has distinct blooming needs. This everblooming variety does not require a dormant period to flower. To encourage more branching and the development of flower buds, prune this species in late spring and mid-summer.

How to Harvest Jasmine Flowers

One of the key advantages of cultivating jasmine at home is knowing that the flowers have not been treated with pesticides. Before harvesting, ensure that you're growing one of the recommended varieties—common jasmine (Jasminum officinale) or Arabian jasmine (Jasminum sambac). Pink jasmine (Jasminum polyanthum) can also be harvested for its aromatic properties.

Jasmine flowers are delicate and should be harvested early in the morning, while the buds are still closed. You can either pick individual blossoms or cut entire stems for easier harvesting. Be sure to remove the flowers from the stem before use. Fresh jasmine blossoms can be added to teas, rice, or desserts, or dried in a cool, well-ventilated area for future use. For the best fragrance, use the freshly harvested flowers in the evening once they have fully opened and released their aroma.

Common Issues with Indoor Jasmine Plants

Jasmine plants are usually resistant to pests, but like all plants, they can show signs of distress when their fundamental needs are unmet. Growing indoors can also introduce pests. Here are a few common issues to be aware of, along with solutions for when problems arise.

Insufficient Light

Jasmine plants may lose leaves if they are not getting enough sunlight. However, leaf drop can also point to watering issues, as discussed below. Try relocating the plant to a sunnier spot, but be cautious of direct sunlight exposure.

Excess Watering

Overwatering can lead to a lack of oxygen reaching the roots, causing them to decay. If your plant is shedding leaves or showing signs of dieback, examine the roots and assess your watering habits. Healthy roots should appear plump and white, while unhealthy ones may look dark and feel mushy. If the roots are damaged, trim them back and repot the plant in a lighter, well-draining soil. Afterward, monitor your watering schedule closely. A soil moisture meter can be a handy tool to determine when to water.

No Flowers

Lack of blooms could be due to insufficient light or not providing a rest period. Ensure your jasmine plant gets a winter break by placing it in a cool area, away from artificial light.

Leaves Turning Yellow

Yellowing leaves can result from water stress, but poor nutrition is another common cause. Applying a balanced fertilizer may help resolve the issue. However, too much nitrogen can encourage excessive leaf growth at the cost of flowers. In such cases, switch to a fertilizer specifically formulated to promote blooming, as it contains less nitrogen.

Pests on Jasmine

Insects like whiteflies and spider mites that commonly infest houseplants thrive in warmer environments. To help prevent both pest problems and encourage flowering, place your jasmine plant in a cooler area. If an infestation occurs, treat it with horticultural oil or soap designed for the specific pest. Keep in mind that new plants often bring pests, so always isolate and carefully treat any new additions to your collection.

Jasmine Propagation

Justin Hancock, a horticulturist at Costa Farms, advises propagating jasmine indoors using cuttings. 'I prefer to take tip cuttings, which come from the new growing shoots of the plant, and ensure they have at least four sets of leaves. Cut just below a node (the point where the leaf joins the stem), remove the bottom set of leaves, and plant the cutting in moist perlite, sand, vermiculite, or potting mix.'

Hancock suggests keeping the cutting in a warm, humid environment, and within a few weeks, you should notice the roots starting to form. 'Bottom heat, in particular, seems to accelerate root development, and using a rooting compound can help as well if you opt for that,' he adds.

If you prefer to propagate your jasmine in water, Hancock shares some tips, although he notes that the above method tends to work better for him. 'I've had less success rooting cuttings in water, but many people prefer this method. Take the same type of cutting and remove the bottom couple of sets of leaves. Place the cutting in a vial or jar of water, ensuring the leaves stay above the water. Change the water as needed, and if you're lucky, roots should begin to develop in a few weeks.'
