Sowing Directly in the Garden:

  • Morning glory seed has a hard seed coat. To aid germination, nick or cut the seed coat with a nail file and soak the seed overnight.
  • Direct sow seeds in average soil in full sun two weeks after danger of frost has passed. Morning glory is a vigorous vine; choose a location next to a support for the vines to climb.
  • Morning glory is not generally recommended for containers.
  • Prepare the soil by removing weeds and working organic matter into the top 6-8 inches of soil; then level and smooth. Morning glory tends to prefer poor soils rather than highly enriched soil.
  • Sow seeds thinly and cover with 1/2 inch of soil.
  • Firm soil lightly and keep evenly moist.
  • Seedlings will emerge in 7-21 days.
  • Keep soil evenly moist but not wet.
  • Thin plants to stand 10 inches apart when plants are 1 to 2 inches high.
  • Do not fertilize unless the plants are showing a nutrient deficiently. Over fertilizing may produce lush green vines with few flowers.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Remove plants after they are killed by heavy frost in fall to avoid disease issues the following year.
  • Morning Glory vines need little care and are easy to grow.
  • Plants can self-sow so allow some to set seeds at the end of the season if you would like it to come back next year. If you would like to prevent self-sowing, remove seed pods before the seeds are released.

Morning Glory, Heavenly Blue is rated 4.7 out of 5 by 23.
Rated 5 out of 5 by from Lovely covering for a wall We wanted to cover the open east wall of our grill picnic area so we would be cooler yet still outside. Just one packet of these morning glories grew fast and thick and made a beautiful covering that also attracted many butterflies.

Rated 4 out of 5 by from beauties I planted these little seeds in May in a part sun area of my garden to grow up a trellis. I did not start to get flowers until September but it's November now and they are going crazy. I must warn you, if you think they are not growing fast enough and think of spraying a solution of seaweed fertilizer and water...don't. Mine did not like that and burned many of the leaves. May be why it's so late in getting flowers, that and planting in part sun. But I plan to grow these again next year in full sun. Very beautiful blue !!

Rated 5 out of 5 by from Easy to grow Churned up ground near fence, threw down the seeds, covered with dirt, watered here and there - and wow, these flowers are something. Spread along fenceline, healthy, lots of flowers. Very little maintenance, water now and then, trim a little. I can't grow nothing - but these were easy and beautiful.

Rated 5 out of 5 by from Fastest germination ever! I bought a packet of this and started the seeds in a wet coffee filter (description follows) at 11 am yesterday morning. At 5 pm the seeds were starting to sprout and little roots were poking out of some of the seeds. Yikes! That's FAST! Coffee filter method: Take a clean white disposable coffee filter, put on some disposable powder-free gloves, and spread the filter on a plate and wet it (cold water). Sprinkle some seed on bottom half of filter, fold the edges in like an envelope, and put it in a Zip-Loc sandwich bag and seal it. Label it. Then check for germination. Take out the filter packet (with disposable gloves on) when roots have sprouted, open it up, and transfer the seedlings to wet expanded peat pellets or filled peat pots or whatever.

Rated 3 out of 5 by from Would have been spectacular, but... ...our tenant complained about the morning glory vines getting in HER way! They were OK until I had to take them out because of her complaints. I hope someday to be able to plant them again. That's the only reason I give it a three-star rating. Turns out that the usual squirrels, raccoons and skunks are not the only pests in the garden! I wonder if Burpee will ever come out with a "tenant repellant"?

Rated 4 out of 5 by from Powerful Bloomer If you are looking for a fast growing powerful vine, this is the one. Many years ago I seeded these in the yard and year after year I have had Heavenly Blue morning glories. One one word of caution, they will free seed like weeds, even root from runners. These guys no how to survive.
