Miscellaneous

Morning Glory

Soil

Well-drained soil of average fertility.

Position

Full sun.

Frost tolerant

None. Morning glory is a warm-season annual.

Feeding

Mix a light application of a balanced organic fertilizer into the soil prior to planting. In midsummer, drench plants with a liquid fertilizer to prolong bloom time.

Companions

Vigorous morning glory vines will twine up any type of support and grow into lush, heavy-blooming plants. They are at their best on a sturdy fence.

Spacing

Single Plants: 7" (20cm) each way (minimum)
Rows: 7" (20cm) with 7" (20cm) row gap (minimum)

Sow and Plant

Sow morning glory seeds indoors to get a head start, or you can plant the seeds where you want the plants to grow at about the time of your last spring frost.
Our Garden Planning Tool can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Morning glory vines are fast climbers that will run up fences, poles, or taller plants such as sunflowers. Morning glory flowers close up during the afternoon hours.

Harvesting

Gather up the old vines after they are damaged by frost and compost them.

Troubleshooting

Many older strains of morning glory quickly become invasive weeds in warm summer climates. ‘Heavenly Blue’ and ‘Flying Saucers’ are safe choices because they set few seeds compared to many other varieties.
