Sunflower Challenge Instructions

  1. Prepare some soil in a container. Don’t worry if you don’t have a plant pot, almost anything will do, including a cleaned-out yogurt pot! Just poke a couple of holes in the bottom to allow for excess water to drain and pack your soil in!
  2. Pop your seeds in the soil. Push them in about 1.5cm deep and cover over with soil.
  3. Sprinkle a little water over the soil. Be sure to regularly water your seeds to help them germinate and grow!
  4. Place your pot somewhere the sun will shine onto it. A windowsill will do! Then wait for your plant to grow and enjoy your flower throughout the summer!

Share regular posts about how you are getting on via Facebook, Twitter, Instagram or your social media network of choice! Remember to use the #SeedSomeSun hashtag and Sheffield & Rotherham Wildlife Trust may share your posts and photos too!

Sunflower Challenge Tips

We’ve compiled a few tips to help you make the most of your seeds and grow the tallest, brightest sunflower plant!

Sunflowers can grow really tall! Once your plant starts getting too big for your pot you may wish to transfer it to a larger pot, or even plant in a sunshiney part of your garden.

To get sunflowers at different times over the summer, why not try growing each your seeds in March, April and May?

Remember to regularly water your sunflower as it grows, especially in warmer times where the soil in a small pot can dry out quickly.

Why not keep a sunflower diary? Regular photos and observations can be really interesting to look back at the progress of your plants throughout the summer.

Remember to keep sharing your progress on social media using the hashtag #SeedSomeSun! We’d love to see how your seeds are getting on and may even share your posts on our own feed!
