Moonflower Vine Plant Care

Moonflower Vine (Ipomoea alba) belongs to the Convolvulaceae family within the Ipomoea genus. Moonflower Vine is native to tropical and subtropical regions of North and South America, from Argentina to northern Mexico, Arizona, Florida and the West Indies. Moonflower Vine is also known as Moonflower, White Morning Glory, Garden Morning Glory.

Moonflower Vine displays a vining, trailing growth habit, reaching up to 15 ft tall with a spread of approximately 3 ft. Moonflower Vine produces showy trumpet-shaped flowers in various colors.

Leaf size: approximately 6 inches.

Ipomoea alba requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Moonflower Vine thrives in full sun to partial shade.

Ipomoea alba grows best at temperatures of 65–85°F. Moonflower Vine prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, fertile soil with added compost or organic matter. Good drainage is essential for Moonflower Vine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Moonflower Vine every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Repot annually in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Moonflower Vine can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to sweet potato vine plant care, which shares the same genus.
