To understand what full sun means, it’s best to inspect your garden first. Eyeball, which garden area is completely exposed to the sun – no trees, no powerlines, no tall fences or walls nearby. Monitor when the sun lights out the site and when it sets.
Morning glories need full sun, optimally over 6 hours a day. Position the plant in an area that’s not shaded and has average soil. They need the sun to feed and thrive. The blooms open with the first sunrays in the morning, so planting them in the shade will kill the plant.
