What is a seed ball/seed bomb ?
Seed bombs/seed balls are a fun and effective way of re-seeding depleted landscapes where you reintroduce. Seed bombs are usually small balls of about 1-3 inch diameter – made of clay, potting soil or compost and seeds. Once they have been made, and dried for 24-48 hours – they are then either sown or more commonly “thrown” across land which needs new flora. Perhaps throw them on the land on the side of highways or barren patches of lands in urban areas like apartment complexes etc or soil on road dividers, to create a green cover.
There are some advantages of using seed bombs instead of using seeds directly:
- Because there are nutrients in the seed bomb in the form of compost or potting mix or cow dung, it gives a leg up to germinating seeds – gives them nutrition in the early days when the young plant needs a little help to survive in harsh conditions.
- The ball prevents animals or birds from eating up the seeds.
- It takes less time to cover a large area – since you can simply throw the seed bombs – so you could, for example, drive around in a car with thousands of seed bombs and a slingshot, and disperse the seed bombs all around while cruising in your vehicle. In fact, there have been scenarios where seed bombs have been used for aerial reforestation by dispersing hundreds of thousands of seed bombs using a low flying aeroplane !
What sort of seeds should you choose ?
You should choose seeds of varieties of plants or trees that are native to the region where you are going to carry out your seed-bombing activity, so that they are likely to survive. You can choose trees as well as plants – for foliage, flowers or even vegetables !
When is a good time for seed-bombing ?
In India, doing it a little before the beginning of the rainy season is great – that’s when the tiny saplings would grow very fast when the first rains hit. Doing it in the middle of the rainy season may wash away the seed bombs.
Steps to make your bag of seed bombs
Here’s what you need:
- 2 parts potting soil or compost
- 5 parts pottery clay mix from an arts and crafts shop or some river bed clay
- 1-2 parts water
- 1-2 parts seeds of your choice
- a bucket to mix ingredients
- a cardboard box to dry and store seed balls
1.Mix the potting soil, clay and 1 part water thoroughly. Make sure there are no lumps.
Slowly add more water until the mixture is the consistency of play dough or toy store modelling clay.
2.Add seeds. Keep kneading the dough until the seeds are well mixed in. Add more water if necessary.
3.Take small bits of the clay mixture and roll into ball about one inch in diameter.
The balls should hold together easily. If they’re crumbly, add more water.
4. Dry seed balls for 24-48 hours in a shaded place before sowing or storing. They store best in a cardboard box. Do not use plastic bags.
This is a great activity for both adults and kids alike – its great fun making these seed bombs with your own hands, as well going on a seed bombing drive with friends and family, once your hand moulded seed bombs are ready !
