Establishment
4-8 weeksRecently rooted cuttings or newly potted plants with limited growth and minimal foliage.
Keep soil lightly moist but not wet. Place in bright, indirect light. Be patient; root development is slow. Avoid fertilizing for first 4-6 weeks.
Vegetative Growth
Spring through early fall, 6-8 monthsLong, segmented stems develop with aerial rootlets. Plant grows rapidly upward and outward, producing new stem segments.
Provide support or trellis for climbing. Water regularly during growing season. Feed monthly with diluted fertilizer (low nitrogen). Stems can reach 10+ feet if supported.
Pre-flowering
Late fall through winter, 8-12 weeksMature stems develop thick buds at the tips. The plant appears dormant with reduced new growth, and buds swell over weeks.
Reduce watering and fertilizing. Provide cool, dry conditions in winter (50-60°F) to trigger blooming. Avoid moving the plant during bud development.
Blooming
Multiple blooms over 4-6 week period, June-August typicallyLarge, creamy-white flowers with yellowish inner petals and purple outer sepals open at dusk. Flowers are 6-8 inches wide, highly fragrant, and last only one night.
Do not disturb the plant during bloom. Keep area warm (65-75°F). Provide adequate humidity. Enjoy the evening bloom—flowers typically open 8-10 PM and close by sunrise.
Fruiting
4-8 weeks from bloom to fruit maturityAfter pollination, small green fruits develop at flower base, eventually turning reddish or yellowish when mature.
Continue regular care. Fruits are edible with sweet, tropical flavor (like a cross between kiwi and strawberry). Harvest when fully colored and slightly soft.

Harvest Tips
Flowers bloom at night and last only until dawn—plan an evening garden viewing to witness the spectacular bloom. Pick fruits when they turn red or yellow and yield slightly to gentle pressure (usually 4-8 weeks after flowering). Harvest in the morning. Fruits should be ripe, sweet-smelling, and easily separate from the plant.
