Best sown in situ, 5mm deep. Prepare the seedbed by incorporating some composted organic matter, remove any stones and rake to a fine tilth. Sow in autumn if you want early flowers the following summer, or in mid spring for a later crop. Thin them out when they are large enough to handle allowing 30cm between each. Deadheading regularly will help prolong the flowering period into autumn. Support the plants with twiggy branches in exposed gardens.
