How to Grow Morning Glories Against a Privacy Fence

Prepare the soil in front of the privacy fence by digging to a depth of 8 to 10 inches. Create a bed approximately 6 to 8 inches wide along the fence to allow for planting a single row of morning glories. Adding organic matter or fertilizer is not necessary, as the University of Illinois Extension explains that morning glories perform best in poor soil with low fertility. Add organic matter only to improve drainage, as morning glories require well-drained soil

Soak the morning glories seeds in a glass of lukewarm water overnight to soften the hard seed coat and speed germination. Some prefer to nick the seed coat with a fingernail file or serrated knife.

Plant morning glory seeds once the danger of frost has passed. Plant the seeds in full sun and to a depth of 1/4 inch, spaced 4 inches apart, and cover with soil. Firm the soil lightly by hand to remove air pockets and secure the seeds.

Water the soil to a depth of 1 inch. Keep the soil moist until seeds germinate in four to seven days, depending on the soil temperature. Morning glories germinate best in soil 65 to 85 degrees Fahrenheit.

Reduce watering to once or twice a week when the seedlings have their second set of leaves. Water thoroughly to moisten the soil to the root level when the soil feels dry at the surface, as morning glories prefer moist soil.

Deadhead morning glories daily to prevent them from going to seed. Deadheading tricks the plant into thinking is has not produced enough blooms to reproduce and encourages more blooms.
