Seed bombs: what is the principle? How to make and use them?


Here is a fun activity to practice with children. But besides being fun, making and then dispatching seed bombs is a ecological act. Let’s see what this concept is, if it is really useful and discover how easily you can shape your seed bombs to launch them … be careful, not just anywhere, because the law does not mess with the notion of land ownership.

Principle of seed bombs

The principle consists of trapping seeds of flowering plants, grass, vegetable plants or even – which is the most common – wild and local plant species in a moist germination substrate. Then you just have to shape them into balls the size of a cap and then catapult them to the desired places. Some gardeners use this concept to seed hard-to-reach areas of their land by playing snipers in the service of a nature that asks only to exist.

Make seed bombs

There is nothing too complicated about preparing your seed bombs. Here are the necessary ingredients:

  • Of seeds, local wild species, vegetables, perennial flowering plants, aromatic plants …, if possible organic because it is even better,
  • 1 handful of decomposed soil,
  • 1 volume of garden soil,
  • 2 volumes of clay powder,
  • Of the’water.

We start by mixing the potting soil, soil and clay well, which must then be gradually moistened so as to obtain a soft dough but who stands. It is kneaded to make small balls 2 to 3 cm in diameter. With the finger, we form a cavity in the center of each ball to be able to place a dozen seeds at most if they are small, or only 3 or 4 if they are large seeds. The hole is then closed. Once properly shaped, these moist balls which contain seeds to be sown should be used immediately. So it only remains bomb the areas that you want to revegetate so that nature can regain its rights.

Obviously, you have to select non-sterile seeds and use the seed bombs as soon as they are prepared, taking into account the season. Spring is the ideal period (as soon as the risk of frost is no longer to be feared), for many plants which will be able to flower throughout the summer, or even until frost depending on the species chosen. Beginners in gardening who do not know the specificities of plants have the possibility ofbuy seed bombs wildflowers on some online sites.

Using seed bombs

Already known in Antiquity, this concept of wild gardening is taken up in the early 1940s by a Japanese botanist. Then he returned to the forefront in the 70s in New York with the aim of reseeding abandoned urban areas and expressing a citizen disapproval against ultra-concrete. This is called the Guerilla Gardening or Green Guerilla, understand gardening guerilla.

Attention it is forbidden to enter private land to distribute seed balls, no one having the right to dispose of the property of others without being expressly authorized by its owner. A short walk through the town hall before playing the pacifist Guerrillas allows you to know a little more about the question because everything depends on the municipalities.

We can reclaim abandoned spaces on the outskirts of cities or ugly urban areas when they are nothing but abandoned wasteland and concrete blocks. The ditches are also places to be exploited, the green roofs, and of course our own grounds. This practice helps to fight against the collapse of biodiversity, but can also be an opportunity to bombard vegetable seeds so that everyone can harvest freely if the bombs contain vegetable seeds. This is a militant act that aims only for the good.

Throwing seed bombs does not make any noise … the only “detonation” that this generates is visually appreciated some time later since the seed bombs give birth to a explosion of colors and scents depending on the plant species that have been sown… This promotes biodiversity.

The result obtained may turn out spectacular, especially if we trap seeds of wild plants in these balls. It’s up to everyone to associate California Poppy, Daisy, Amaranth, Marigold, Cornflower, Sunflower, Primrose, Nasturtium, Poppy … In this way, you can radically transform an area of ​​your own garden or along the often dreary pedestrian paths. This is the solution that guarantees a rapid development of all these plants and it’s perfect for attract pollinating insects without spending hours sowing seeds one by one.
