At its best:
Jul, Aug, Sep
Plant seedlings into well prepared soil, about 20-25cm apart (check seed packet for spacings of larger flowers). Once planted, firm the soil around the rootball.
Water well to enure the roots are moist, and that the soil is settled around the rootball.
Flowers sown in March or April will be in bloom by July. Sow a new tray every two weeks until mid-May, to ensure your display will last right through the summer. Start cutting flowers as soon as they show colour, so that they last longer indoors.
Don't harvest all the flowers, as simple blooms provide pollen for bees, butterflies and other beneficial insects.
Towards the end of summer, leave a few flowers to ripen and develop seed heads. Once the flowerhead dries out, carefully collect the seeds and store in a cool, dry place, so you won't have to buy as much seed next year.
