Where to Plant Morning Glory

Plant morning glories in a location where they'll get lots of sun every day. It climbs naturally on whatever it's planted near. Use them to cover up an unsightly chain-link fence, for example. Or grow them on a trellis to provide a living privacy screen for your deck, patio, or balcony.

How and When to Plant Morning Glory

Start morning glory vines in early spring by sprinkling seeds where you want them to grow. Sow the seeds about 1/4 inch deep and a few inches apart. Watering regularly promotes blossoming, though it may take a few months to see any flowers.

Morning Glory Care Tips

These fast-growing flowering vines are easy to care for.


Morning glories grow best—and blossom most prolifically—in full sun, so plant them where they'll get at least 8 hours of direct light per day during the growing season.

Soil and Water

Spreading a 2- to 3-inch-deep layer of mulch over the soil after you plant them will help keep weeds at bay and allow the soil to stay moist longer, so you have to water less often. Once established, they're somewhat drought-tolerant, but the plants look best if watered regularly. Otherwise, their large, heart-shaped leaves tend to wilt during the heat of the day.

Temperature and Humidity

Morning glories will grow whether it's warm or cold. They can even live through early frost and continue to flower. Grow morning glories as annuals in colder locations where temperatures approach freezing in the winter and as a perennial in warmer tropical or subtropical climates. They thrive in both arid and humid environments.


Use a low-nitrogen fertilizer every month during the growing period to fertilize morning glories. For more flowers, use a high-phosphorous product.


Morning glories don't usually require pruning except in fall after frost has killed the foliage. But if the plants start to grow larger than you want and begin to get out of hand, you can prune them back during the growing season without harm.

Pests and Problems

Wildlife love to eat morning glory flowers. Deer, groundhogs, rabbits, and other critters will chew on the lower blooms of morning glory vines, causing damage to the plants. The best way to prevent them from eating your vines is to build a 5-foot high fence around the plants. Morning glory is also susceptible to fungal diseases like leaf spot and white blister.

How to Propagate Morning Glory

If you live in an area with short summers, it's helpful to plant morning glory seeds six to eight weeks before your last expected frost date in spring to help give them a head start on the season. Otherwise, purchase transplants from your local garden center and put them out after all danger of frost has passed.
