Sunflowers (Helianthus annuus) are known as the ‘Giants’ of the summer flowering annuals. This is due to their large, bright yellow flowers that can grow up to 35 cm wide on a tall branching plant that can reach up to 1.5 metres high! If stretched for space, there are dwarf varieties available, so you can still get the bright colours of these flowers in a small area.

How to grow sunflowers in a garden

  1. Choose a spot in the garden that receives full sun and is sheltered from strong winds.
  2. Prepare the planting area well by digging in Yates Dynamic Lifter Organic Plant Food.
  3. Sow seeds directly where they are to grow and cover with soil. Firm down and water well.
  4. Keep moist through germination period. 
  5. Once seedlings are approximately 5 cm, mulch with an organic mulch, such as bark chips, woodchip or pea straw.
  6. Once flower buds start to form, feed with Yates Thrive Rose & Flower Granular Plant Food. TIP: For an added boost apply Yates Thrive Roses & Flowers Liquid Plant Food.


How to grow Sunflowers in a pot

  1. Choose a pot at least 200 mm wide and deep. Position in full sun that is also protected from strong winds.
  2. Fill the chosen pots with quality potting mix, such as Yates Premium Potting Mix. 
  3. Plant directly into the pot, cover and water in well.
  4. Keep moist through germination period.
  5. Once flower buds start to form, feed with Yates Thrive Roses & Flower Liquid Plant Food. TIP: For an added boost apply Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate.
