What is preparation 504?
Stinging Nettle
Tea is added to compost and sometimes sprayed on low vigor vines to increase Magnesium content.
What is preparation 505?
Oak Bark
Finely ground oak bark is placed in a livestock skull and buried in a swamp to ferment. Applied to compost to increase Calcium content.
What is preparation 506?
