Seed bombs are a clever way to bring some colour and beauty into a barren piece of your garden and are great fun for kids to make. A seed bomb is basically seeds mixed with other ingredients and formed into a ball or a shape and then dried out. Once dried they can to given as a gift or thrown in your own garden. The basic principle is once the seed bombs get wet the outer layers start to disintegrate as the seeds inside start to germinate. Eventually, you will have a gorgeous bunch of blooms to enjoy where your seed bomb landed.
There are two types of seed bombs that you can create, one where the seeds are mixed with air dry clay and compost or one that uses pulped paper to incase the seeds. Both can be made into balls or shaped in a cookie cutter or silicone mould. The clay version tends to be a little more rustic whereas the paper ones can be made in a huge array of colours. Use a coloured paper of your choice or add some food colouring to it.
Seed bombs are becoming increasingly popular to give as DIY wedding favours and they work very well in a rustic-themed setting. They can be made to compliment any wedding colour scheme and look lovely in an organza bag with perhaps a personal tag added.

There’s plenty of seed mixes you can use for your seed bombs. You can use any seeds you like but mixed flower seeds are more fun as you never know what array of flowers will appear. They’re also great for the environment as they’re loved by butterflies and bees. If you want to specifically help the honey bees we’d recommend including lavender, foxgloves, honeysuckle and crocus seeds. For butterflies include buddleia, red valerian, sedum and hebe seeds.

How to make clay seed bombs
You Will Need
- Air dry clay in the colour of your choice
- Flower seeds
- Cookie cutter or silicone mould (optional)
- Rolling pin
- Plain paper
Take a piece of air dry clay in the colour of your choice then flatten out into a rough circle.
Sprinkle some multi-purpose compost on top of the clay followed by a layer of flower seeds.
Fold the circle in on itself then knead together so the compost and seeds are evenly distributed through the clay.
Take small pieces of the clay and roll into balls approximately 2cm in size. Leave to dry for at least 24 hours.
Alternatively, to make heart shape seed bombs roll out the clay to approximately 1cm thick.
Use a cookie cutter to cut out heart shapes then leave to dry for at least 24 hours.
How to make paper seed bombs
Take several sheets of your chosen paper and trim into 2.5cm squares. Place in a bowl then cover with water. Leave to soak for at least an hour.
Transfer the paper squares and water to a blender cup then blend. If the paper squares are getting stuck to the sides, add a little more water, shake the cup then blend again until you have a smooth pulp.
Remove the pulp from the blending cup then squeeze out all the excess water. Place the squeezed pulp in a bowl.
Sprinkle flower seeds on top of the pulp then work them in thoroughly with your hands.
Lay a heart cookie cutter on a flat surface then take a small ball of pulp and push it firmly into the base of the cutter, approximately 1.5cm thick. Remove the cutter then leave the heart to dry for at least 24 hours.
