How To Grow & Care For Morning Glory

Morning Glory

Morning Glory is a common name for over 1,000 species of flowering plants in the family Convolvulaceae. These plants are well-known for their vibrant trumpet-shaped flowers that bloom in the early morning and close by the afternoon. They are often found in gardens, where they can add an alluring touch with their beautiful shades of blue, pink, purple, white, or red.

The Morning Glory vine is revered not only for its stunning appearance but also for its rapid growth. With proper care, it can easily cover a wall, trellis, or fence, providing a colorful backdrop. Its hearty nature, coupled with its minimal requirements, makes it a favored choice among gardeners.

However, some species can be invasive in certain areas, so care should be taken to manage growth and prevent unwanted spreading. The seeds of certain species also contain LSA, a substance that is considered toxic, so proper caution should be taken if children or pets are around.

Morning Glory Care

Morning Glory is a relatively low-maintenance plant, thriving in a variety of garden settings. Providing a trellis or some support will allow the vines to climb and create a beautiful vertical display. They prefer full sun and well-drained soil but are quite adaptable.

Although they’re not particularly thirsty plants, regular watering during dry periods will keep them looking their best. A balanced fertilizer can be applied sparingly, as too much can lead to more leaves and fewer flowers.

Light Requirement for Morning Glory

Morning Glory vines thrive in full sun. They need at least 6 to 8 hours of direct sunlight to bloom profusely. Lack of sufficient sunlight may lead to reduced flowering and weaker growth.

Soil Requirements for Morning Glory

Well-drained soil is preferred, but Morning Glories are adaptable and can tolerate various soil types, including sandy, loamy, or clay soils. They are not very particular about soil pH either.

Water Requirements for Morning Glory

Water Morning Glories regularly but not excessively. While they can tolerate drought, consistent moisture, especially during dry spells, will promote healthy growth and blooming.

Temperature and Humidity

Morning Glories are best grown in temperatures between 65-85°F (18-30°C). They can withstand higher temperatures but may suffer in prolonged cold. Humidity doesn’t significantly affect their growth.


Use a balanced fertilizer sparingly, as excessive feeding can lead to vigorous growth of leaves at the expense of flowers. A slow-release granular fertilizer applied in the early growing season can be beneficial.

Pruning Morning Glory

Pruning is necessary if the vines become too dense or spread beyond the desired area. Cut back as needed to maintain shape and encourage air circulation, which helps prevent diseases.

Propagating Morning Glory

Propagation can be done through cuttings or seeds. Cuttings should be taken in late spring, whereas seeds can be sown directly into the garden after the danger of frost has passed.

How To Grow Morning Glory From Seed

Soaking seeds overnight or nicking them will improve germination. Plant seeds ¼ inch deep in well-drained soil, spaced about 6 inches apart. Keep soil moist until seedlings are established.

Invasive Growth

Some species can become invasive; monitor growth and prune as needed.

Pro Tips

  1. Provide support like a trellis or fence for the vines to climb.
  2. Be mindful of the potential invasiveness and choose species accordingly.
  3. Soak seeds overnight to aid in germination.
  4. Plant in full sun to ensure vibrant blooms.
  5. Monitor growth and prune as needed to control spread.
