Growing Information

How to Sow

You can sow sunflowers in containers, but they germinate so easily that direct sowing will be just as good. They just need a light covering soil - about 3mm, and though they can do without a lot of water when they are bigger, you will need to keep the soil wet while you wait for them to germinate.
