What you need to know to Plant & Grow
Morning Glories possess hard seed coats and sensitive roots; soaking seeds prior to direct outdoor sowing yields the highest success.
-
Seed Preparation: Soak seeds overnight in warm water for 12 to 24 hours before planting to soften the hard seed coat and speed up germination.
-
Direct Sowing (Recommended): Morning Glories resent root disturbance, so starting indoors offers no advantage. Direct sow pre-soaked seeds outdoors in mid to late May once soil has warmed. Plant seeds 6 mm deep and 7.5 cm apart in moist, well-draining soil in full sun.
-
Germination & Thinning: Seeds will germinate in approximately 2 weeks. Thin young vines to 15 cm apart when they reach 7.5 cm in height.
-
Support & Fertilizer Care: Provide a strong trellis, wire fence, or netting for vines to wrap around. In naturally rich soil, avoid high-nitrogen fertilizers to prevent excess foliage growth at the expense of flowers. In poor soils, apply a balanced, dilute fertilizer regularly to maintain vigour and bloom output.
