Sunflowers are the most satisfying plant a kid can grow. They sprout fast, grow really tall (some reach over 3 metres!), and the big yellow flowers make everyone happy. Plus, the seeds are a snack for birds — and you!
🛒 What you need
- 1 sunflower seed (you can buy a packet from any nursery or hardware store)
- A pot at least 30cm wide and deep, or a patch of garden
- Good soil with some compost mixed in
- A sunny spot — sunflowers need sun all day
- Water every day or two
🌱 How to plant it
- Fill your pot with soil and compost.
- Poke a hole about 2–3cm deep with your finger.
- Drop the seed in and cover it up.
- Water it gently — just until the soil is damp, not flooded.
- Put it somewhere sunny and check it every day!
🔍 What to watch for
- Days 5–10: A tiny green shoot pokes out of the soil. That is your sunflower saying hello! 👋
- Weeks 2–4: It grows fast now — measure it each week and mark on a stick how tall it is.
- Weeks 8–12: The big yellow flower opens. Bees will come visit it. Let them — they are friends!
- At the end: When the flower dries out and turns brown, the seeds are ready. You can save them to plant next year, or leave them for birds.
🧪 Fun experiment to try
Plant two sunflowers. Put one in full sun and one in a shadier spot. Watch how differently they grow. Which one is taller? Which one flowers first? Write down what you see each week — you are doing real science!
❓ Why does a sunflower follow the sun?
Young sunflowers actually turn to face the sun as it moves across the sky each day — this is called heliotropism. The side of the stem in the shade grows faster than the sunny side, which bends the flower toward the light. Once the flower is fully grown, it stops moving and stays facing east to catch the morning sun and warm up the insects that come to pollinate it.
