Morning glory (Ipomoea): Sowing, planting and harvest calendar
How do you sow morning glories under cover?
For ornamental morning glory sowing under cover, check the name and packet. Seed-grown annuals such as Ipomoea purpurea are started in spring for planting after frost. The group also includes cold sensitive perennials whose propagation and timing may differ.
Use clean individual pots with drainage holes and premoistened seed compost. Soaking or light scarification may be specified for some hard-coated seeds. Apply only the preparation recommended for your batch. Sow at the supplier's depth rather than one rule for every species, then water gently.
Keep warm according to the packet, with good light after emergence. Maintain moisture without saturation, ventilate any cover and avoid overheating in sunshine behind glass. Label name and date. Seeds remain horticultural material kept apart from food, because some morning glories are harmful if swallowed.
Let roots hold the ball together before changing pots, disturbing them as little as possible. Provide a small support when stems lengthen. Gradually acclimatise outdoors and wait until frost risk has passed. Final space depends on the type's vigour and available support. Keep young vines from tangling together while they grow.
