Reasons to buy your seeds from Thompson & Morgan

1 packet (50 morning glory seeds) (KA7432)


Start off in a seed tray indoors and plant out in borders or containers. Soak seeds overnight in tepid water before sowing. Fill a seed tray with good, free-draining, damp, seed compost. After the seeds have soaked overnight, sow seeds on the surface of the compost and cover with a very fine sprinkling of dry vermiculite or finely sieved compost. Place the seed and tray in a propagator or seal inside a polythene bag and keep at around 20-25C (68-77F) until the seeds germinate. This will take about 7-30 days. Don’t exclude light as this helps germination.

When the seedlings are large enough to handle, transplant them individually into 7.5cm (3") pots or multi-cell trays. Before planting out, acclimatise the plants to cooler conditions by putting them outside for a few hours a day for a few weeks. Plant out when all risk of frost has gone about 30cm (12") apart.
