I think you
should try it, and I think that's what
Fukuoka taught us: to experiment and see what works. And when something doesn't work, we try something else, and if something unintentional accidentally works, then we start doing that intentionally.
I've made little seed balls by hand and put a few seeds in each, but I guess that's the hard way to make seed balls. But I guess that's what you have to do if you don't have many seeds.
However, if you start planting your vegetables and flowers, then you could start saving their seeds and have many more for next year. It's not that hard to save seeds because instead of putting them in compost buckets, we can put them on towels to dry.
