The term seed bomb or seed bomb actually comes from the field of guerrilla gardening. This is the term used to describe gardening and cultivating land that is not owned by the gardener. This phenomenon is more widespread in English-speaking countries than in Germany, but it is also gaining more and more followers in this country, especially in the big cities. Your weapon: seed bombs. Whether homemade or bought ready-made: They make it easy to add greenery to fallow areas in public spaces, such as traffic islands, green strips or abandoned lots that are difficult to access. A well-aimed toss from a car, off a bike or conveniently over a fence is all it takes to make plants sprout from the ground.

Where to use seed bombs?

Seed bombs should be used exclusively in urban areas. In nature reserves, agriculturally used areas, on private property or similar they have nothing lost. In cities, however, they are a wonderful way to make the city greener and promote biodiversity. Attention: Before the law, planting in public space is damage to property. Similarly, seeding on private property or fallow land is prohibited. A criminal prosecution is nevertheless very unlikely and rather rare to expect.

History of seed bombs

The seed bomb was invented by a Japanese rice farmer named Masanobu Fukuoka, a proponent of nature-based agriculture. He used his nendo dango (seed balls) after World War II, mainly for sowing rice and barley. Visitors who came to his farm in the 1970s then brought the idea of seed soil with them to the West – and thus carried it around the world. They were first used in the 1970s, when American guerrilla gardeners began using them to green up New York. They also gave the seed bombs their names, which are still in use today.

How do seed bombs work?

Throw, water, grow! There is basically nothing more to it. The best time to "go up" seed bombs to leave is in the spring, ideally just before rain sets in. A seed bomb basically consists of soil, water and seeds. Many add a little clay (clay powder, clay soil), which keeps the balls better in shape and protects the seeds from animals such as birds or insects, as well as adverse weather conditions.

What seeds are suitable for seed bombs?

If you want to make seed bombs yourself, you should use seeds from native plants. Non-native plants can become a problem because they have no natural competition in this country and thus proliferate uncontrollably. You upset the ecological balance. The most famous example of such an invasive species is the giant hogweed, also known as Hercules’ weed. Be sure to use only untreated seeds and choose plants that can cope with the urban climate. Marigolds, lavender, marigolds and cornflowers have proven their worth, as have coneflowers and mallows. Wildflower mixes especially attract bees, bumblebees and butterflies, so they benefit wildlife at the same time.

Herbs and various vegetables can also be planted out by seed bomb. Rocket, nasturtium, chives or even radishes can be spread very well by seed bombs and, as long as they get enough water, they will thrive even in the city without much help.

The seeds in the seed bomb should be adapted to the particular local conditions

For shady sites, we recommend plants like cranesbill or borage. Wild grasses, thyme or corn poppy do very well with little water.

Make your own seed bombs: This is how it works

Meanwhile, seed bombs are also available in many stores. The bombs range from sunflowers to butterfly meadows to wild herbs. You can also easily make seed bombs yourself. Pi times thumb you need for a square meter ten seed bombs.


  • 5 handfuls of clay powder (optional)
  • 5 handfuls of soil (normal plant soil, gladly mixed with compost)
  • 1 handful of seeds
  • Water


The first thing to do is to sieve the soil finely. Then mix the soil with the seeds and clay powder well together in a large bowl. Add water drop by drop (not too much!) and knead the mixture until an even "dough" is formed is formed. Then shape them into balls about the size of a walnut and leave them to dry in a place that is not too warm and well ventilated. This usually takes about two days. If that takes too long, you can also bake the seed bombs in the oven at a low temperature. You can throw the seed bombs immediately afterwards. You can also store them in a cool, dry place for up to two years.
