Blueberries are fairly delicate plants and vulnerable to weed competition.  To suppress weed growth, we use ramial woodchip (chipped smaller twigs and leaves, rather than trunk) that has an ideal carbon-nitrogen ratio for decomposition. To help the plants absorb nutrients, we inoculate each one with ericaceous mycorraeze before planting. These fungi live both within the plant roots and within the soil, greatly increasing the roots absorptive area thereby enhancing nutritional uptake.  We conduct yearly leaf tests to ensure that we use the correct balance of organic fertiliser to optimally nourish the plants.   We apply this fertiliser through a fertigation system delivered to each plant, targeted precisely at the roots. This minimises fertiliser consumption. The fertiliser we use is a highly diluted organic amino acid that is easily absorbed and the high level of dilution avoids damaging the soil microbial and fungal life.
