How to Prepare Morning Glory Seeds


Morning glories have deep blue flowers that bloom for just one day, but are quickly replaced by new buds. They bloom in the morning and early part of the day then fade as the day warms up. A vining flower, they climb trellises, columns and fences and may reach heights up to 18 feet. Grown as an annual in most of the United States, morning glory is started from seeds. Morning glory has a hard seed coat that needs some preparation before it will germinate.

Step 1

Fill a bowl with warm tap water. Soak seeds in the water overnight the day before you plan to plant them.

Step 2

Remove seeds from water and lightly nick the seed coating with a knife. Nick the outer seed coat so the white underlying area is just visible. Alternatively, scuff the seeds with a file or sandpaper to reveal the white inner coat.

Step 3

Sow seeds directly into the planting bed outdoors. Plant in a well-drained area in full sun.

Step 4

Space seeds 12 inches apart near a support structure such as a trellis. Water well at planting. Germination occurs in 7 to 14 days.

Step 5

Water during extended dry periods; otherwise no further care is needed for the morning glory vines to thrive.

Tips and Warnings

  • Morning glory will self seed. Remove seed pods as they form if self seeding is a problem in your garden. Do not nick the seed coating of seeds that have already begun to split open after soaking, as these are already germinating.
