Caroline Kim takes us through the step-by-step process of making seed bombs that gardeners on the go drop into the soil of barren, forlorn spots. Start with organic earthworm castings. Then add clay soil. Mix dry.
With the seed bombs stowed in her red bag, the stiletto-wearing Caroline takes off on her bike in search of vacant patches of public space. To plant the seed bombs, she digs holes with a trusty tool the heel of her shoe. Stilettos work really well, she says, grinning.
