Veronica Lorson Fowler A favorite of our grandmothers, nothing beats the morning glory for fast greenery and pretty flowers. Plant morning glory from seed no more than a week before your region's last frost date. Soak seeds in warm water for 24 hours before planting to speed germination. Choose a site that has full sun and well-drained, average soil. Working a spade or two of compost into the soil is good idea.
Plant seeds about an inch deep.
Even if you need just one morning glory, plant at least two or three seeds for insurance. Depending on the morning glory variety, supports need to be 10 to 12 feet high. Check the seed packet for the plants' ultimate height. As the plants grow, start them on their support by gently twining them around the support. They'll take off on their own after that.
