Last week I wrote about "seed bombs" and how to make them. Seed bombs are essentially seed balls with a sometimes nefarious purpose. The clay and compost balls are tossed into vacant city lots or barren fields and flowers and grasses sprout depending on the seed in the seed bomb.
For a more aesthetic seed ball, a family gardening project, and a fun gift idea, consider making seed balls from recycled paper. Instead of clay and compost, paper holds the seeds together in the ball.
To make the pulp you'll need a blender or food processor. I recommend using one that is old and not regularly used for your meals. Inks in the paper will be transferred to the plastic and are hard to clean. I purchased a used food processor from Goodwill for a few dollars. It's now dedicated to the task of making seed balls.
The paper needs to be torn or shredded before adding to the blender. If you pack in a wad of paper and then add water you'll probably burn up the motor pretty quickly. Smaller paper pieces work better.
I began with four full sheets (four pages each) of newspaper and ran the newspaper through my paper shredder. I've also used shredded bills and junk mail to make seed balls. The shredded paper breaks apart easily in the blender when water is added.
Working in batches, put the torn or shredded paper in the blender and add water. I've found that soaking the paper in a tub of water before adding it to the blender helps it break apart easier. Even if it was soaked beforehand you'll still need to add water to the blender.
The paper needs to turn into a mushy mash. The blades of the blender or food processor will rip the paper into shreds only when it is overly saturated. If you don't use enough water you'll get a clump that just bounces around the blender or stays in one place, not breaking apart. Add more water as the blender is blending until you get the paper thoroughly disintegrated and a mushy pulp develops.
Remove the pulp and set it in a bowl or put it into a colander to allow some of the water to drip out. Continue blending all your paper and water in small batches until all of it is pulp.
At this point try to remove a good part of the water by pressing or squeezing the pulp with your hands. Discard the water or save it for another batch. With the pulp very damp, but not dripping water, transfer it to your mixing bowl.
I added 1/4 cup of wildflower seeds to the entire pulpy mass that four sheets of newspaper produced. Using my hands I kneaded it all together like making bread dough. You want the seeds to be fully mixed into the paper pulp.
When it's all incorporated, takes small pieces of the mix and press them into molds, into cookie cutters, or form them with your hands into balls. I find that using small cookie cutters give you a greater variety of shapes to choose from. Keep adding the pulp and seed mixture until the mold is filled.
The seed balls will need to dry so removing as much water as you can at this point will accelerate the entire process. Begin by compacting the paper as much as you can to force water out and then soak up the water with paper towels or newspaper. These blotting materials can be turned into more seed balls later on.
Gently remove the seed balls from your mold and let them dry for a few days. Removing them allows you to use the mold for the next batch and also give the seed balls exposed surface area for drying. They'll expand slightly in the process.
By using water tinted with a few drops of food coloring you can get seed balls of any color you like. You can also try shredding colored paper and mixing that with water. Varying the shapes and colors provides wonderful gift opportunities.
Making seed balls with recycled paper works well on many levels. You reuse waste materials while adding fun to planting. It's not as messy as the clay seed balls can be and the finished products look better. The entire project takes just a few minutes and the paper seed balls can be stored for months before giving away or being planted.
If you're looking for a fun gardening project, try making recycled paper seed balls.
