Make wildflower seed bombs

Gather wildflower seeds and make your own seed bombs for a colourful display next summer with this easy step by step guide.


Making your own seed bombs is a fun and easy way to attract pollinators to otherwise-neglected wasteland. At the end of the wildflower season, allow the seeds to dry on the plant, then deadhead the plant and place the flowerheads in a paper bag. Give the bag a good shake to collect the seeds and leave them to dry out further in a cool, dark place. Autumn is an ideal time to throw your seed bombs.


You Will Need

  • Seeds (1 cup), collected from flowerheads or a packet of shop-bought UK wildflower seeds
  • Peat-free compost (4 cups)
  • Clay powder (3 cups)
  • Water (1-2 cups)
  • Mixing bowl

Step 1


In the bowl, mix the seeds with four cups of compost and three cups of clay powder. Use your hands to ensure the seeds are evenly distributed.

Step 2


Slowly add water and knead the mix together until you have a firm consistency and your seed bombs stick together.

Step 3


Roll the mix into balls; aim for the size of a 50-pence coin. Lay the bombs on a tray in a warm spot and leave them to dry out. 

Step 4


Simply throw your seed bombs on bare soil on roadsides, urban tree pits, railways or verges. Distribute in autumn to see blooms in spring.
