A microbial inoculant that gets to work at the root zone
Bush Doctor Microbe Brew is a liquid microbial inoculant built from a complex blend of ingredients designed to help plants achieve better root efficiency and nutrient uptake. Rather than feeding the plant directly, it encourages rapid microbial colonisation around the root system, building the biology that supports long-term nutrient availability.
It suits both hydroponic and soil applications, and Fox Farm recommends it across ornamental flowers, evergreens, vegetables and trees, applied every other week through the vegetative and blooming cycles right through to harvest. Because its role is to build root-zone biology rather than deliver a nutrient hit, it works best as a routine addition to a full feeding schedule rather than a one-off treatment.
- Complex microbial blend formulated for root zone colonisation
- Supports enhanced nutrient uptake through improved root efficiency
- Suitable for ornamentals, vegetables and trees, not just fruiting crops
