Seed Balls – Green Science

Take gardening and planting to a fun new level with balls of clay and seed.

Sometimes, gardening and planting seeds can be very boring. This can especially be the case if you are a young scientist that loves action and excitement! Thankfully, there are gardening methods that can offer a bit more kick than just digging holes and planting. Introducing Seed Balls, the method of gardening that allows you to throw to sow!

Experiment Materials

  • Modeling clay
  • Various plant seeds
  • Potting soil
  • Cookie sheet or wax paper

Experiment

  1. Knead the clay to soften it. Once the clay is moldable, flatten and shape the clay into a disc shape.
  2. On top of the clay, add 1/2-teaspoon of potting soil and 1/4-teaspoon of plant seeds.
  3. Fold the clay inward, keeping the soil and seeds from spilling out. Mold the clay into a ball around the soil and seeds.
  4. Mix some soil and seeds together on a flat surface.
  5. Roll your clay ball through the soil and seeds. Try to get an even covering of soil and seeds on the clay.
  6. Knead the soil and seeds into the clay to incorporate them into the clay ball.
  7. Repeat until you have all of the Seed Balls you desire.
  8. Allow the clay to dry by setting the balls on a cookie sheet or wax paper for a few days.
  9. Once they've dried, take your balls outside and toss them in the areas you want your plants to grow.

How Does It Work?

Seed balls are a great method of reclaiming areas of your garden that have become thin or barren. The clay vessels that you create for your seeds and soil offer a fun way to plant your seeds while providing protection for the exposed seeds. The soil you wrap inside of the ball offer the seeds an immediate source of nutrients. The seeds remain inside the Seed Ball until rains soak the clay and stimulate the seeds.
