Seeds are magical! Every seed is a capsule of new life. And seed bombs are a great way to spread seeds in hard to reach or disused spaces as well as being a wonderful way to excite kids about seeds and growing. Seed bombs don’t belong in or near our native bush land but are great for a fun approach to beautifying your garden or concrete urban corners.
Making seed bombs is an engaging, messy, fun way for kids to learn about seeds and growing plants. And lobbing bee-food seed bombs into unused space is a fun way to create a better environment for our pollinators and promote more biodiversity.
Bees and other pollination insects love flowers. Spring is the perfect time for seed bombing with flowering annuals that the bees will love.
Great seed bomb seeds for our pollinator friends in Canberra in Spring include: cosmos, sunflower, buckwheat, calendula, cornflower, alyssum, borage, marigold, wallflower, and more. Seed bombs with local native flower seed are a great idea too!
*Seed bombs made with non-native flower seeds should not be thrown into or near our wonderful bush land as these plants can become invasive in the bush. Seed booms are great for urban and inner suburban environments.
Seed Bomb Recipe
* some Canberra clay (3 parts) – try digging this out of your garden and sieve to get rid of debris.
* some good quality compost (5 parts)
* bee food seeds – native or introduced flowers (a few for each bomb).
You might need to mess around with the proportions in the mix. You want the mix to be sticky and to easily form a ball.
Mix compost and seeds in bowl, add clay and water. Roll small balls – less than the size of a golf ball. You can roll the balls in a light mix of small seeds for decoration and extra chances at germination!
In spring, throw the bombs a couple of days before rain, when temperatures are warming up. If balls are going to be kept for a while, dry in a cool dark place, quickly, so seeds don’t germinate in storage.
Seed bombs are great for kids to have fun playing with and learning about seeds, and to watch plants pop up. It’s a great way to get kids excited about seeds.
Please keep bombs away from bush land including suburban bush land.
Just like growing anything, germination and success will be variable so make lots and lots to increase your chances!
