Growing Jasmine (Jasminum polyanthum): Fragrant Indoor Vine

Initial Care

Place in cool room with bright, indirect light. Cooler temps prolong bloom.

Humidity

Jasmine hates dry air from radiators/vents. Use humidifier or pebble trays (water below pebble tops). Refill often.

Water & Bloom

Water when top ½ inch of mix is dry. No soggy soil. Bloom begins late Jan/early Feb if conditions met.

Post-Bloom & Summer

After bloom: 6+ hours direct sun, normal temps. Move outdoors after frost, gradually to full sun. Fertilize every 2–4 weeks (spring–early fall) with half-strength houseplant fertilizer. Withhold fertilizer fall/winter.

Pruning & Bud Set

Prune to control size/shape but stop by August 1 (buds set in late summer). For next winter's flowers: 4–5 weeks of 40–50°F nights, plenty of sun, complete darkness after sundown. Bring indoors before frost; cool, indirect light until bloom.
