Can you please advise on when in the spring I should plant morning glory seeds? I will be planing them in containers to grow up a lattice on my balcony, which faces west. Thank you!
Morning Glories come from the Ipomoea family and are closely related to the potato vine plant. They are annuals and each flower only lasts for one day, blooming in the morning, hence the term “morning glory”. As they are annuals they will not over winter but are known to self seed. They need weather that is 22 degrees F or warmer to germinate, and will probably not survive a frost. So to get a head start on the season you may wish to start the seeds inside in peat pots about 4-6 weeks before planting out after the last frost. Otherwise you may not benefit from their blooms until late in the season. They don’t like having their roots disturbed, so transplant the young seedlings in their peat pots.Soaking the seeds in water for 24 hours before planting will speed germination. If you are okay to wait for the blossoms you can sow the seeds directly in to your containers when you are sure the last frost has passed.
Here is a great article from Fine Gardening on growing Ipomoeas https://www.finegardening.com/plants/articles/morning-glories-moonflowers.aspx
