The sunflower cycle

Sunflowers are one of the biggest flowers we can grow in our gardens. Why not challenge you friends and family to grow the tallest ones? You can use your new growing knowledge to help


For this activity, you’ll need:


  • Sunflower seeds – we recommend LG Sunny Giant Sunflowers, RHS Sunflower Teddy Bear, or Sunflower Van Gogh varieties
  • Small pots
  • Compost
  • Fertiliser
  • Wooden stakes (you can also use branches)

Step 1: Planting your seeds


  • Fill your pots with compost
  • Sow one seed into each pot making sure it’s 1.5cm deep
  • Place them in a cool, bright spot in a greenhouse or porch
  • After the shoots start to appear, keep them well watered



Step 2: Transferring seedlings


  • Once your plant grows sets of leaves, they’re ready to plant outside
  • Prepare the soil by removing weeds and add fertiliser or manure
  • Plant the sunflowers as deep as they were in the pot and water well

Step 3: Helping your sunflowers grow


  • As your plants grow towards the sun, add stakes to protect them from the wind
  • They’ll need plenty of water, and you can keep adding fertiliser until the flowers bloom

Step 4: Collecting seeds for next year


  • Each flower head is full of seeds
  • Let the flowers dry out before removing them
  • Store them somewhere cool and dry so they can be planted again next year

What else can I do with my sunflower seeds?

Sunflower seeds have so many other uses. Here are a few of our favourites:

  • Tie up your dried flower heads so birds can eat the seeds
  • Use them for baking bread or muffins
  • Add them to salads
  • Use them in crafts

We’d love to see how tall your sunflowers grow. Take a picture and share them with us by using #DobbiesLittleSeedlings and tagging us
