Jasmine thrives in a warm, humid, and well-ventilated environment with plenty of light. It prefers bright conditions, as strong sunlight leads to sturdy branches, dark green leaves, and abundant, fragrant blooms. If it doesn’t receive enough light, the plant may produce fewer flowers and lose its fragrance. In colder regions, especially in the north, potted jasmine should be brought indoors during autumn and winter, ideally placed on a south-facing windowsill to maximize sunlight exposure.
Jasmine is not drought-tolerant but also does not like overly wet conditions. During the rainy season, make sure to drain excess water from the pot to prevent root rot and yellowing leaves. In hot summer days, water the plant twice daily—once in the morning and once in the evening. If you notice the leaves curling, mist them lightly to help maintain moisture and support healthy growth.
For optimal growth, jasmine requires well-draining, fertile soil that is slightly acidic (pH 6–6.5). Sandy or loamy soils are ideal, as they provide good aeration and nutrient retention. Heavy clay soils can lead to poor root development, resulting in weak stems, thin leaves, and small, less fragrant flowers. To improve soil quality, mix in organic matter or use a balanced potting mix designed for flowering plants.
Fertilization is important during the midsummer growth period. Apply organic compost, bone meal, or a balanced fertilizer rich in phosphorus and potassium every two weeks. However, if the plant becomes lush and leafy without flowering, it might be due to excessive nitrogen. In such cases, reduce nitrogen-rich fertilizers and focus on phosphorus and potassium to encourage blooming. Also, ensure the plant is in a sunny and well-ventilated area.
Pruning is essential to maintain a compact and bushy shape. Trim potted jasmine regularly, keeping the base between 10–15 cm to encourage strong new growth. When new shoots grow to about 10 cm, pinch them back to promote branching and more flowers. After flowering, remove spent blooms promptly to conserve energy and stimulate new growth, leading to denser foliage and more blossoms.
Pests like aphids, spider mites, and scale insects often attack jasmine from July to September. These pests feed on flower buds and can weaken the plant. To control them, spray the plant with insecticides such as permethrin or cypermethrin diluted at 200 times. Apply the spray every two weeks, even if no pests are visible, to prevent infestations. Choose sunny mornings or late afternoons for spraying, avoiding direct midday sun to prevent leaf burn.
During the flowering period, avoid watering the flowers directly, as this can cause premature wilting and reduce fragrance. If it rains, move potted jasmine indoors or under shelter to protect the blooms from excessive moisture. With proper care, your jasmine will thrive and reward you with beautiful, fragrant flowers throughout the growing season.
