Propagation of Ipomoea plants


Question
I have an Ipomoea morning glory plant that I would like to grow next year.  The flowers have died and have left what I believe to be a little round green seed.  What do I do to grow this plant again.

Answer
Hi Paul,
Thanx for your question. If the seed of your morning glory are from a hybrid variety the seed will not come true.  That means the plants that will develop from them will not resemble the parent plant due to hybridization.  The round structures you describe are the seed pods and there will be black or dark brown seed a bit larger than the size of a pinhead.  Allow the seed pods to completely dry.  While they are green, they are not ripe and if picked will not develop into viable seed.  Morning glory seeds germinate rapidly in warm temperatures.  You can start them indoors about 2 weeks before the last frost in your area.  Some people soak the seed over night.  I do not.  To me, it is an unnecessary step but others claim it speeds up germination.  Press the seed into potting soil and keep in a warm room.  They will generally germinate in about 5-7 days.  Keep the seedlings under a 40-watt flourescent shop light and gently prick them out and plant in separate pots or cells after they are a couple of inches tall.  The ground needs to be warm in order for them to survive and you can place a piece of black plastic over the flower bed, weighing it down with bricks.  It should warm the soil up sufficiently in a couple of weeks.  Take the seedlings outdoors and place them in the shade after all danger of frost has subsided for about 10 days.  After that, poke holes in the black plastic and plant the seedlings and water them.  Do not feed them.  High nitrogen will only make more green growth so avoid Miracle grow.  You can use some composted cow manure or diluted fish emulsion.  I hope this helps.
Tom
