Indoor jasmine plants typically receive filtered or indirect sunlight, as direct exposure through windows can sometimes scorch their leaves. They thrive near east or south-facing windows with bright but diffused light. In contrast, outdoor jasmine enjoys full sun to partial shade, depending on the climate. In hotter regions, afternoon shade helps prevent leaf burn, while cooler climates allow for more direct sunlight, promoting vigorous blooming.
Indoor jasmine prefers consistent temperatures between 60-75°F (15-24°C) and appreciates higher humidity levels, which can be achieved with humidifiers or pebble trays. Outdoor jasmine is more adaptable but thrives in warmer climates (USDA zones 7-10). It tolerates temperature fluctuations better but may need protection from frost. Humidity is naturally higher outdoors, benefiting the plant's growth and flower production.
Indoor jasmine requires careful watering to avoid root rot. The soil should be kept moist but not soggy, with good drainage. Outdoor jasmine, however, benefits from natural rainfall but may need supplemental watering during dry spells. Overwatering is less of a concern outdoors due to better soil drainage and airflow, but waterlogged conditions should still be avoided.
Indoor jasmine grows best in well-draining, peat-based potting mixes with occasional fertilization (every 2-4 weeks during the growing season). Outdoor jasmine prefers loamy, slightly acidic soil enriched with organic matter. Fertilization is less frequent but more robust, often applied in early spring and mid-summer to support blooming.
Indoor jasmine requires regular pruning to control size and encourage bushiness, as limited space can restrict growth. Outdoor jasmine, with more room to expand, needs pruning primarily to shape the plant or remove dead wood. Vigorous outdoor varieties may require more aggressive trimming to prevent overgrowth.
Indoor jasmine is prone to pests like spider mites and aphids due to lower air circulation. Regular misting and insecticidal soap can help. Outdoor jasmine faces threats from caterpillars, scale insects, and fungal diseases but benefits from natural predators like ladybugs. Proper spacing and airflow reduce disease risks outdoors.
Indoor jasmine may bloom less profusely due to lower light levels, though fragrant varieties like Jasminum polyanthum adapt well. Outdoor jasmine, with ample sunlight and space, produces more abundant and aromatic flowers, especially in warm climates where conditions mimic its native habitat.
Indoor jasmine requires minimal seasonal adjustment, though reduced watering in winter is advised. Outdoor jasmine may go dormant in colder climates, requiring mulch or frost protection. In tropical regions, it grows year-round with minimal care.
