How do you grow Ipomoea?
Posted by Suttons Customer Services on 19 December 2013 09:28 AM


Sow the seeds in pots about 1cm (½") deep at a temperature of 18-20°C (65-68°F) from February to April. Soak the seed in tepid water for 24 hours prior to sowing. Sow the seeds individually in small pots or three seeds to a 15cm (6")pot. Germination usually occurs in 5-20 days. Grow on the plants at a temperature of 13°C (55°F). It is important to avoid checks in the early stages of growth, as chilling of the plants is likely to cause chlorosis (yellowing of the leaves), from which the plants may not recover. Sowings can also be made where they are to flower outdoors during May.

Harden off the plants before planting them outdoors in June. Plant out in a sunny, sheltered position against a wall, fence or in a border, and provide a trellis or cane support. The plants can also be grown in large pots in a cool greenhouse. Ipomoea grow to a height of 2.5-3m (8'-10') in a good summer. Avoid over feeding the plants as it can result in a lot of leaf growth at the expense of flower production. In dull summers or in shade growth and flowering can be disappointing.
