Morning glories are beautiful flowers that seem to reward a gardener for ignoring them. With little care and attention, morning glories will climb happily up a trellis, fence or string to cover the vertical surface with vivid blooms. In fact, morning glories thrive in poor soil rather than the standard rich loam that many gardeners strive to create. Gardeners needing something easy to grow with bright blooms should include morning glories in their landscapes.
Fill the paper cup with warm water the night before you want to plant the morning glories. Place the morning glory seeds into the warm water and allow them to soak overnight. This will decrease the germination time of the seeds. Another way to achieve this is to use nail clippers to nick each seed to break the hard outer coating of the shell.
Choose a sunny location with something vertical for the morning glories to climb. The vines will climb easily up a trellis or along a fence. Tie vertical strings above the planting area (up a mailbox post, for example) to train the vines up a vertical surface. Do not amend the soil or try to improve the soil quality because morning glories prefer poor soil.
Plant the seeds in the ground after the last spring frost. Drain the seeds from the water (if you soaked them) and plant them in the soil under a quarter-inch of dirt. Space the seeds every 3 to 4 inches along the vertical support they will climb.
Water the morning glory seeds immediately after planting and keep them evenly moist throughout the growing season. Add a light layer of mulch around the soil to control weeds, if desired.
Allow the morning glories to climb at will. They will grow quickly and cover your vertical support with green foliage and trumpet-shaped blooms that open in the mornings and close again in the late afternoon.
