The Green Guerillas
Wildflower seed bombs are a great way to add a splash of floral colour and greenery to neglected urban sites. The practise of seed bombing has its roots in 1970’s New York, when an artist called Liz Christy mobilised a group of Lower Eastside residents to take action against the urban decay in their neighborhood. This clandestine group of gardeners called themselves the Green Guerillas and the seed bomb was their weapon of choice.
The original seed bombs contained water, peat moss, and fertiliser – and were encased in Christmas decorations and water balloons. The Green Guerillas threw these into abandoned lots, neglected sites and hard-to-reach places all over the city. The group also sowed plants in window boxes of derelict buildings and planted sunflowers on the central meridian of busy New York streets.
The practice became known as ‘guerilla gardening’ and started to gather momentum around the city. Their efforts culminated in their commandeering of a vacant lot on Bowery Street and transforming it into the city’s first ever community garden, The Bowery Houston Farm and Garden. The garden is still thriving today and makes up one of 600 similar spots all over the city.
How Does a Seed Bomb Work?
Nowadays, there are more environmentally friendly methods for making seed bombs such as using peat-free compost and bio-degradable potter’s clay. The clay acts as an outer shell that protects the seeds while the compost keeps the seeds moist. Once planted, the clay in the seed bomb will begin to break down, releasing the germinated seeds and allowing them to take root in their new home.
Where to Plant a Seed Bomb
Before choosing your site, make sure the land isn’t being used for agricultural purposes. You don’t want your seed bombs to interfere with crops or other plant life. Also, be sure to choose seeds that are indigenous to your location and suitable for the time year.
Choose areas that could benefit from some natural beauty, such as abandoned lots or neglected pots and planters. Provided there is some dirt, all the seed bomb needs to thrive is sunlight and rain water.
