Growing Grandpa Ott Morning Glory Seeds

Bee introduces how to plant

Sow Morning Glory: Nick the pointed end of the morning glory seed with a nail clipper or knife. After nicking, seeds can optionally be soaked in water up to 12 hours. Then, sow in 2 in. pots or cell packs, cover with ¼ in. of soil. Kept at 70°F., seeds germinate in 7-21 days. Morning glory seed can be direct sown after all danger of frost, 6-8 seeds per foot. Thin seedlings to 12 in. apart.

Grow Morning Glory: Grow in full sun. Morning glory vines need good drainage, tolerate drought and poor soil. Blooming is heavier and growth is faster with regular water. Avoid overwatering and nitrogen-rich soils which produce more leaves and few flowers. Rarely bothered by pests or disease. Flowers from midsummer until frost. Hummingbirds love trumpet-shaped morning glory flowers.
