Seed Bomb Recipe 

2 parts potting soil 

5 parts pottery clay mix 

1-2 parts water 

1-2 parts seeds of your choice 

Large tub to mix ingredients 

Large box to dry and store seed balls


  • Mix the soil, clay and 1 part water thoroughly. There should be no lumps. 
  • Slowly add more water until the mixture is the consistency of molding clay (yes, the one you played with as a child). 
  • Add seeds. 
  • Keep kneading the dough until the seeds are well mixed in. 
  • Add more water if necessary. 
  • Take small bits of the clay mixture and roll into a small ball. The balls should hold together easily. If they’re crumbly, add more water.
  • Dry seed balls for 24-48 hours in a shady place before sowing or storing. They store best in a cardboard box. Do not use plastic bags. 
  • The last step in how to make flower seed balls is sowing them. You can plant them wherever you like, maybe somewhere you go often. 
  • No need to water them, they look after themselves!
