Sowing & Growing

Between October and late March, sow seeds in pots filled with high-quality seed compost, and nurture them in a cold frame. After the threat of severe frosts has diminished, transplant the seedlings into the garden or pot them for patio growing. Alternatively, direct sowings can be done in October or from March to April.

For optimal growth, enrich the planting hole with ample well-rotted organic matter before planting. While in the growth phase, provide a balanced liquid plant food every two weeks, and regularly deadhead to promote continuous flower production.
