How to grow Morning Glory plants
Plant Morning Glory seeds indoors in the months of March and April. The seeds of Morning Glory plants are very hard. Soak seeds overnight in water to soften the seed coat. After they have been soaked overnight, they should have swelled up and will appear to be larger in size. Sow the seeds about 0.5 centimetres deep in trays of compost. Water them and place in a warm position on a windowsill or in a greenhouse at a temperature of about 15 to 20°C.
Keep the compost moist. The seeds should germinate in 14 to 21 days. The photograph below shows a young seedling:
When there is no more chance of frost plant the seedlings outside in pots, or directly in the soil. They are usually planted out in the months of May and June. Plant them about 30 centimetres apart.
Morning Glory plants are fast growing climbers. They grow to a height of about three metres (10 ft). Use a supporting rod like the one in the photograph below to support the plant.
Morning Glory plants have a long flowering season. They flower the same year as sown. They flower in the months of June, July, August, September and October. The flowers are a beautiful violet colour and the centre of the flower is shaped like a star, as shown below.
Morning glory is a half hardy annual, so collect the seeds for replanting the following spring.
