If you've got these ingredients at home you can make your own seed balls/bombs.
8tsp of flour
1tsp of seeds
water (8-16 tsp)
1. Mix the dry ingredients together
2. Add water a little at a time to create a sticky, but not too wet concoction.
3. Shape the mixture into balls the size of a marble. Be gentle when mixing so the seeds don't get damaged.
4. Air dry for at least 24 hours.
Voila! When they are dry they can be scattered where you would like the flowers to grow, in a natural/unstructured pattern!
Note: this recipe is a variation to the seed balls made with clay as I struggled to find powdered clay. However, it is important to mention that flour balls might be more attractive to birds than the clay ones.
