Morning glories make up most of the Ipomoea family. Characterized by fast-growing vines, species of this family are both annual and perennial, evergreen and deciduous. Some bloom year-round while others only bloom during the growing season. Those that are perennial overwinter in USDA zones 9 to 11, where the temperature stays above 30 degrees F. Knowledge of how to grow this plant will help you produce a healthy, attractive vine.
Sand over the coat of the seeds to scarify them. Seeds in this family have a tough outer covering that needs weakening. Sand it only so much so that the seed takes on a dull appearance.
Choose an area in full sun with well-drained soil of almost any variety. Ipomoea can withstand poor soils, but does best in moist, well-drained soil of average fertility.
Dig about 6 inches deep into the soil with a spade. Break up clumps and loosen compacted soil, removing any rocks as you see them.
Plant the scarified seeds about 1 inch deep. Some species of morning glory do not do well with transplantation, so your best bet is planting them directly outdoors. Space plants 8 inches apart for smaller species such as Ipomoea convolvulus and up to 60 inches apart for large species such as the Ipomoea pes-caprae.
Water the Ipomoea seeds immediately after planting, keeping them moist until they germinate. This plant family can withstand some drought once established. The seeds should germinate within one or two weeks.
Pull out any weeds that appear, especially while the plants are young. The young plants do better without the competition for water and nutrients that the weeds bring.
