Sunflowers can be sown straight into the earth where you want them to flower. First prepare the ground so that it is weed free and rake over the soil so it is represents fine breadcrumbs.
Make some drills approximately 12mm deep and plant the seeds, taking care to cover them with soil. Be sure to leave a 10cm space between each seed to allow them room to grow and thrive.
Water the seeds gently ever day or so and watch them grow! You may want to support the first shoots with garden canes until they are established. Be careful not to overwater your sunflowers before and after flowering as it might damage the heads.
Sunflowers like full sunlight and thrive in temperatures of between 20 and 26C, and grow well in a variety of soils, including sandy and clay.

Remove any submerged leaves as they will soon start to rot.
