Ipomoea | Morning Glory

Seed Treatment:

  1. Scarification:

    • Gently nick or file the seed coat using a nail file or sandpaper.
    • This helps water penetrate the hard outer shell.

  2. Pre-Soaking:

    • Soak seeds in warm water (not boiling) for 12–24 hours before planting.
    • This softens the seed coat and encourages quicker sprouting.

Sowing Instructions:

  • Timing:

    • Direct sow after the last frost, when soil temperatures reach 65–75°F (18–24°C).
    • Can be started indoors 4–6 weeks before the last frost for an early start.

  • Sowing Depth:

    • Plant seeds ¼ inch (6 mm) deep.
    • Lightly cover with soil and firm gently.

  • Spacing:

    • Space seeds 6–12 inches (15–30 cm) apart.
    • If growing on a trellis, thin to 12 inches (30 cm) apart after germination.

  • Soil Requirements:

    • Prefers well-drained, moderately fertile soil.
    • Tolerates poor soil but thrives in a neutral to slightly acidic pH (6.0–7.0).

  • Watering:

    • Keep soil evenly moist during germination but avoid overwatering.
    • Once established, morning glories are drought-tolerant and require minimal watering.

  • Germination Time:

    • Seeds usually sprout in 5–21 days.

  • Sunlight:

    • Requires full sun (at least 6–8 hours of sunlight daily).

Additional Tips:

  • Provide a trellis, fence, or support for climbing varieties.
  • Avoid over-fertilization, as too much nitrogen promotes leaves over flowers.
  • Morning glories self-seed readily, so deadhead spent flowers to prevent excessive spreading.
