Seedling
2-3 weeksSmall heart-shaped cotyledons emerge; true leaves develop within 1-2 weeks. Vines are tender and delicate.
Keep soil moist but not soggy. Provide gentle air circulation. Start seeds indoors 4-6 weeks before last frost or direct sow after frost danger passes. Seed scarification with sandpaper may improve germination.
Vegetative Growth
3-4 weeksRapid vine extension with multiple stems growing outward. Dense foliage of heart-shaped leaves develops along stems.
Provide sturdy trellis or support structure early. Guide vines onto support as they grow. Water regularly and maintain consistent moisture. Fertilize every 2-3 weeks with balanced or slightly phosphorus-rich fertilizer to encourage blooming.
Flowering
8-12 weeks or until frostTrumpet-shaped flowers with distinctive pink stripes on white/pale background appear at leaf axils. Flowers typically open in early morning and close by afternoon.
Maintain consistent watering and feeding schedule. Deadhead spent flowers to encourage more blooms, though not strictly necessary. Provide adequate air circulation to prevent powdery mildew. Stake or guide vines as they climb.
Peak Bloom
4-8 weeks, or longer in warm climatesVine is covered with numerous open flowers, creating a vibrant display of pink-striped blooms. Flowers appear continuously throughout summer and fall.
Continue regular watering and feeding. Monitor for pests and diseases. Support heavy vine growth with additional ties or pruning to prevent breakage from wind or weight.
Decline/Senescence
Until frost (annual zones) or winter (perennial zones)As temperatures cool in fall or frost approaches, flowering slows and foliage may yellow. Seed pods may develop on remaining flowers.
In warm zones (9+), the vine may persist through winter and resprout. In cooler zones, pull plants after frost. Allow some flowers to set seed if you want self-seeding next year.

Harvest Tips
Morning glories are ornamental vines grown for flowers rather than harvest. Enjoy blooms by viewing them in early morning when flowers are fully open. If collecting seeds for next year, allow some late-season flowers to develop seed pods; collect pods when they turn brown and dry, then extract seeds. Flowers typically close by midday.
Fun Facts
