If you’ve ever planted seeds, you may have consulted the back of a seed packet, and tried to follow the exact planting directions. But what if you could just toss a ball onto soil, and still grow flowers from seed?
With seed bombs, and undemanding seeds like those of wildflowers, you can do just that. Made from colorful paper pulp, this is a fun project to do with kids, and seed balls make a great gift or party favor. It takes just 20 minutes to make plus drying time.
How To Make Colorful Seed Balls:
Make paper pulp
Put ½ cup of water in a blender. Tear 2-3 same-colored sheets of construction paper and 2 to 3 sheets of newspaper into pieces about 1 to 2-inch-square, creating about 2 to 3 cups of torn paper total. Place it in a blender. Blend until the paper is pulverized, adding more water if needed.
Place a sieve on top of a bowl and pour in the paper pulp. After five minutes, press on the pulp with the back of a spoon, or your hands, to remove any remaining water.
Pour the water out and then transfer the paper pulp to the bowl. Stir a packet or two of seeds into the paper pulp. Smaller seeds are easier to incorporate into a seed ball. Different types of seed may be combined, but check that they can all be sown at the same time of year and have similar light and soil requirements.
Grab a handful of the paper pulp and seed mixture, and squeeze it into a ball around the size of a golf ball. Squeeze out any excess water while compacting and shaping the ball.
Place balls on a tray or plate and let dry for at least 2 to 4 hours on a warm windowsill, or in front of a fan or vent. Drying times vary based on temperature and humidity. Finished seed balls will feel dry to the touch, lighter in weight, and will have lightened in color.
The best time to plant seed balls is before a rainy period when there will be enough moisture for the balls to disintegrate and the seeds to germinate and grow. Or toss in a pot filled 2/3 full with potting soil, and water well.
Check local lists of invasive plants, and exclude them from your seed balls.
