A flower seed bomb is a ball made of compost and seeds, which is held together with a mix of flour and water. Once the bomb has been thrown, the seeds will begin to germinate and the bomb will slowly break apart – the loose compost then provides somewhere for the seeds to start growing into flowers.
April to June is the time for seed bomb-making and it’s a great way to spend a rainy morning. It’s a great activity for children, who will learn about different types of seeds and flowers, how they grow and what wildlife they attract.
Here’s How to Make Flower Seed Bombs in 10 Simple Steps
Duration: 15 minutes + drying time
You Will Need:
- Flower seeds
- Cheap flour
- A bucket
- A mixing bowl
- A wooden spoon
- An old mug for measuring
- Plastic apron(s)
- Somewhere to throw your seed bombs – with the landowner’s permission!
Prepare Your Mix
- Step 1: Using your mug as a scoop, add 3 mugfuls of compost to the bucket.
- Step 2: Empty the seeds into the bucket and mix everything together with your hands.
- Step 3: Get your separate bowl ready for step 4.
- Step 4: Fill your mug with flour and add this to the empty bowl.
- Step 5: Add some water, a little at a time, and stir with a wooden spoon – keep adding water until your flour mixture is thick and gloopy.
- Step 6: Pour the flour and water mix into the bucket containing the compost and seed.
- Step 7: Mix everything together with your wooden spoon – it should form a thick ‘dough’.
- Step 8: Break off a piece of ‘dough’, gently roll it in your hands and make a golf-ball-sized seed bomb. Repeat until you’ve used up all the dough.
- Step 9: Place the balls on a tray (or in a box) and let them to dry for 24 hours.
- Step 10: Head outside to the garden to scatter your seed bombs!
Flower Seed Bombs – Top Tips
- Ideally, make your seed bombs the day before rain is forecast, throw your bombs before the rain arrives and then leave them to benefit from the downpour.
- To stop birds eating the seeds, add a little paprika to the mix – they don’t like it!
- In winter, when the birds need some help, make some seed bombs containing bird seed (and no paprika).
