KNOW that comfrey and yarrow (right) can be added to the compost
heap to speed up the breakdown process, but how much do you need
to add - and how often? Also, do you have any idea of ratios of
comfrey to seaweed if making a liquid fertilizer? And does it need
to be diluted?
has a high protein and potash content. The leaves can be cut, allowed
to wilt and then put in trenches before planting crops such as potatoes.
Or you can make them into a liquid fertiliser by soaking the chopped
leaves in a bucket of water for at least a week. The liquid can
then be watered directly onto the compost heap as new layers are
added, or diluted down to the colour of light tea and watered occasionally
onto crops that like potash, such as potatoes, tomatoes, peppers
and fruit trees.
Yarrow also has the
ability to concentrate copper, phosphates and potash from the soil.
Its leaves can be used in a similar way to those of comfrey.
Both comfrey and yarrow
have the ability to activate compost heaps. Any leaves added to
the heap will help speed up the production of loam. When making
a liquid fertiliser of seaweed, add as much yarrow and comfrey as
you can gather. Soak well for several weeks and apply at the strength
of weak tea.
