The morning glory, or Ipomoea violacea, comes in a wide range of blossom colors. The morning glory is a perennial flowering vine, but it is grown as an annual plant in most regions. The vine is tender but fast-growing, easily climbing trellises or fences. Its flowers are funnel-shaped and open in the morning. You can start morning glory seeds indoors or sow them directly into the ground in the springtime. Whichever way you choose, planting morning glory vines from seeds is simple.
Nick the seeds' hard coating carefully with the tip of a small, sharp knife. Soak the seeds in warm water for at least two hours or overnight.
Start your morning glory seeds in peat pots or a drainage tray filled with a mixture of one part vermiculite, one part perlite and one part milled sphagnum moss. You can also use a commercially made soilless growing mix.
Plant the morning glory seeds 1/4 to 1/2 inch deep. Space the seeds at least 6 inches apart.
Place the seeds in full sunlight, watering the medium daily to keep it moist. Apply a weak fertilizer solution once each week after the seeds germinate. Purchase a liquid fertilizer for flowers and cut the dosage to 1/3 to 1/2 strength.
Transplant your sprouted morning glory seedlings into 6-inch planter pots filled with an all-purpose potting mix or a mixture of one part compost or garden soil, one part perlite or vermiculite and one part sphagnum moss. Keep your seedlings in their pots for three to four weeks, until they develop an established root system. Place the seedlings in full sunlight and maintain temperatures between 65 and 70 degrees F. Cut back on watering from daily to twice each week or just frequently enough to keep the potting mix thoroughly moistened.
Begin feeding the seedlings with a full-strength fertilizer dose once every one or two weeks when the seedlings are 3 or 4 weeks old. Transplant your seedlings into large planter pots or plant them outdoors when they've developed their second set of leaves, their larger "true" leaves.
