How do you germinate morning glory seeds?
Soak the seeds in warm water for 24 hours before planting, or carefully file or chip their hard overcoats to encourage germination, then soak them. Put them in peat pots so the transition into the garden won’t disturb their roots as much. Seeds will germinate in about a week.
How long does it take for morning glories to sprout from seed?
When starting morning glories from seed, it can take 2 ½ to 3 ½ months before they begin blooming. In northern climates where cold winters and shorter growing seasons are the norm, it’s best to start morning glories from seed indoors four to six weeks before the last frost date.
How do you grow Ipomoea purpurea?
Ipomoea purpurea needs full sun or semi-shade exposure and warm weather. They do not resist frost. They prefer a soil rich in organic matter and well drained but they adapt to poorer but permeable soils.
Do you pinch out morning glory seedlings?
Pinch Seedlings in Spring To encourage branching and rapid growth, you should pinch back seedlings when they have a couple of sets of true leaves. Cut them back about half an inch from the tips. You can also pinch off the tips of any lateral stems that develop after that.
Do morning glory seeds need light to germinate?
Morning glories prefer full sun but will tolerate very light shade.
What month do you plant morning glory seeds?
spring
When to Plant Morning Glories Sow morning glory seeds in late spring or early summer, once the ground has warmed to about 64°F (18°C). Morning glories are tender annuals, so they are sensitive to cool temperatures and late frosts.
Do morning glories come back every year?
MORNING GLORY BASICS Annual in areas that get below 45 F, but can still reseed and come back year after year on their own; perennial in warmer, more tropical climates.

How does Ipomoea indica spread?
Ipomoea indica spreads by seeds, and vegetatively via rooting stem fragments. Seeds are dispersed by wind, rain, waterways, gravity, and human activity while stem fragments are commonly dispersed by water, animals, and vehicles and in dumped garden waste ( Weber, 2003; Smith, 2010; Queensland Government, 2017 ).
How many seeds does Ipomoea have?
Flowering can occur throughout the year. The fruit are globular papery capsules (about 10 mm across) containing four to six dark brown or black coloured seeds. Ipomoea indica reproduces primarily from broken fragments of stems that produce new roots at the nodes.
How does Ipomoea reproduce?
Ipomoea indica reproduces primarily from broken fragments of stems that produce new roots at the nodes. Hence a common mode of dispersal is believed to be as a consequence of gardeners dumping unwanted vegetative material. It may also be dispersed by vehicles.
