How to care for Cosmos bipinnatus Sonata White ('Pas1789') (Sonata Series):
Pot on and grow on in a well-lit and ventilated frost free environment (such as a greenhouse, coldframe or conservatory). Plant out after all risk of frost has passed.
Pinch out the growing tips to encourage bushier growth, and feed at regular intervals throughout summer with a high-potash fertiliser. Taller plants may need supporting with brushwood stems in exposed positions.
