What is a seedbomb?

Josie Jeffery

In an exclusive extract from her new book, Seedbombs: Going Wild with Flowers, author and gardener, Josie Jeffery, explains the seedbomb phenomenon

When I tell people I make seedbombs, they look puzzled and ask, ‘What is a seedbomb?’. They think they are edible (some fancy new superfood) or a cosmetic product. Rarely do people think they are horticultural. I smile and begin a well-rehearsed explanation. Firstly, they are NOT EXPLOSIVE OR EDIBLE! A seedbomb is a little ball made up of a combination of compost, clay and seeds.

‘What is it for?’
The compost and clay act as a carrier for the seeds so they can be launched over walls or
fences and into inaccessible areas such as wasteland or railways. ‘But what is the point? Why can’t you just throw seeds loose?’ Most seeds are very light and there is risk of them being blown away by the wind, making them unsuitable for launching long distances.

‘How do I make them?’
There are various ways of making seedbombs. You need to find a carrier for the seeds. My method uses natural ingredients – compost and clay. The compost offers nutrients for the seeds to germinate and grow strong during their infancy and the clay binds the seedbomb, making it hard enough not to break when it hits the ground.

‘How do they work?’
