INGREDIENTS OF SEED BALLS
Seed balls usually contain a mixture of seeds. For
reclaiming derelict ground or reforestation a wide selection
of appropriate species are used. Mixtures can also be used for
setting up edible systems that include seed of nitrogen-fixing
plants and companion plants.
Mixtures are used for experimentation, some things will fail
to establish themselves; those that succeed will be the most
suitable for that location. Much can be learned by observation
of results. The making of seed balls is very easy, but choosing
the right species to include is not so obvious and the introduction
of non-native species should always be carried out with thought
Fukuoka recommends red clay because it contains more
minerals, especially iron and manganese, than most gray clays.
Depending on needs and location choosing local clay, that is
the basis of local soil and contains local microorganic life,
may have good results.
Compost or humus reach soil is required. Compost from
your own local soil is best, as it contains local soil microorganisms.
Making seed balls
Use approximately 2 parts seed to 3 parts of dry sifted
compost and 5 parts of powdered red clay. Mix in well, then
gradually add water until the right constancy is reached for
rolling into balls of about a half-inch in diameter. (Number
of seeds per ball will vary depending on seed size). Seed balls
are then left outside to dry, and can then be scattered or stored
long term until needed.
A minimum of ten seed balls per square metre, a higher
density may be required to reclaim derelict land.
Do not water seed balls they will absorb water from
the ground, dew, rain and the air around them and sprout when
the time is right.
