Seed balls are a mini-ecosystem that protects seed from birds, ants and slugs and gives them the nutrition they need to flourish. You don’t need to be a gardening expert to use seed balls. You don’t need to spread the seed, or even plant these! Simply throw on top of soil, and let nature run its course!

In this post, we are going to learn how to make our very own DIY seedballs to unleash your inner nature activist.

Seedballs are ideal for wildflower or tree seeds, and you should choose the species suited to the target climate and conditions.

Seed balls are composed of seed, clay (to protect the seed from ants, mice, birds etc.) peat-free compost (to give seeds a boost) and chilli powder (an extra predator deterrent).

This ancient technique of seed propagation provides all the nutrition and protection that a seed requires for its early growth – which is particularly useful for growing wildflowers, as their seeds often take longer to germinate and grow than other garden plants.

Seed balls can be dispersed during any season, but spring and autumn is usually an optimal time to start wildflowers growing. Wildflower seed balls can be started in the summer with success, but flowers won’t bloom until the following spring/summer, once they get going though they will improve their display with each year!

Here is a simplified recipe to make your own DIY seed balls:


  • Flower or tree seeds
  • Potter’s clay powder, from any craft shop
  • Peat-free compost
  • Water
  • A bowl
  • A baking tray

Mix the seed, clay, and compost together in a bowl to a ratio of three handfuls of clay, five handfuls of compost, and one handful of seed.

Then carefully add water slowly and gradually (you don’t want it too gloopy).

Mix it together until you get a hardness that you can form into truffle-sized balls.

Lay them out to bake dry on a sunny windowsill for at least three hours.

Then unleash your inner rebel by throwing (or even catapulting!)  your seedballs where you want nature to reclaim the space!
