Use a good multipurpose compost to fill 7.5cm pots to 1cm below the rim. Tap each pot to settle the compost and firm gently.
Sow one seed per pot - sunflowers germinate reliably and form large seedlings. Poke the seed into the compost.
Cover the sunflower seed with about 1.5cm of compost. Label each pot and water well so that the compost is just moist throughout.
Cover each pot with a plastic bottle 'cloche' to keep seedlings warm. Plant your sunflowers outside in June when the last frosts are over.
