Seed-bombing is hotly debated. Is it livening up waste ground with native plants to support wildlife? Or is it dropping unwanted seeds without permission?
We recommend a less-controversial approach – use seed bombs as a way to green your own space – growing wanted plants on authorised land makes seed-bombing a great activity.

A note on materials

Muddy Faces recommends using natural rather than air-drying clay. Air-drying clay usually has nylon fibres in it to help reinforce it when it dries – these can get into the natural environment.
For the same reason we suggest you do not decorate with glitter (as is sometimes suggested), as the small particles are plastic and do not break down naturally.

Step 1

Mix together some garden compost and wildflower seeds.

Step 2

Add a little water and tightly compact small handfuls into balls

For a more sturdy ball, roll out some circles of natural clay

Hold the circle in your hand and mold it into a pocket.

Gently fill the clay with the seeds and compost mixture, then mould the whole thing into a ball.

Step 3

Leave the clay balls in the sun to dry.

Step 4

Throw your bombs onto the area you want to seed.
