Scarlett O'Hara Morning Glory Seeds

For better germination scarify the seed coat with sandpaper or a nail file and then soak in warm water overnight. The seed coat is the main culprit behind the problem of poor sprouting. After that sow Scarlett O'Hara Morning Glory seeds directly outdoors when the soil temperature is above 60°F. Sow ½ inch deep and 4 to 6 inches apart. You can also start them indoors 3-4 weeks before the last expected frost, but note that morning glories don't like their roots disturbed, so use peat pots that can be directly planted. Allow 7 to 21 days for germination.

Red Morning Glory flower produces the most bloom when planted in full sun. Six or more hours a day is a minimum to strive for. Partial shade will also work, but you'll have fewer blooms and longer internodes, so your vine will look leggier. Make sure your soil drains well. Waterlogged soil will kill these plants quicker than drought. Average garden soil is okay. In fact, richly bedded soils will cause more foliage than blooms. Water well until your plant is established, and then back off. Once roots are well-established, your Scarlett O'Hara Morning Glory will do surprisingly well in drought.

Scarlett O'Hara Morning Glory plant needs something to grab onto right away, something like a trellis, fence, or string. The vines will twine on their own, but without something to support them, they'll sprawl and get all matted on the ground, which will lead to rot. No heavy pruning is required, just keep the errant vines under control before they lignify. Deadheading isn't really necessary for reblooming, but it does keep the plant looking nice. Don't overfertilize with too much nitrogen, otherwise you'll end up with a plant with lots of green and no red blooms.
