Make 1.2cm deep holes leaving 10cm between each seed hole and then place the seed into them carefully.
Cover the seed with soil and then water the seeds gently.
Water well after planting and continue to water well as they grow.
As the sunflower grows taller, you may need to help support the stem.
You can support your sunflower plant by placing a cane near the stem and loosely tying the cane to the plant with a string.
