Morning glory plants are easily started by seeds sown directly in the garden after the threat of frost has passed and the soil has warmed up. Indoors, the seeds should be started about 4-6 weeks before the last frost in your area. Since morning glories have relatively hard seed coats, you should soak the seeds in water overnight or nick them before sowing. Sow the seeds of morning glory about ½ inch deep and give them about 8- to 12-inch spacing. Once plants have reached about six inches or so in height, you may want to provide some type of support for the vine to twine around. Those planted in hanging baskets can simply be left to spill over the container’s edge.
How to Grow Morning Glory Flowers
Growing morning glories is easy. They’re great for containers when provided with a trellis or placed in a hanging basket. Morning glories prefer full sun but will tolerate very light shade. The plants are also well known for their tolerance to poor, dry soils. In fact, the plant can easily establish itself in any slightly disturbed area, including garden edges, fence rows and roadsides where the vine is commonly seen growing. Even with the plant’s tolerance of poor soil, it actually prefers well-draining soil that is moist, but not soggy.
