A tonic built from seaweed, fish and composted manure does more than feed the plant on top, it wakes up the biology in the soil underneath. This concentrate carries thirteen strains of living microbes along with a broad nutrient spread, so it's working on two fronts at once.
Mix 40mL into 9 to 10 litres of water and it covers about 8 square metres per watering can. One litre makes up to 250 litres diluted, which is enough for regular monthly feeding right through a season without buying more.
Gentle enough for the whole garden, including natives, and genuinely useful after transplanting or through a stretch of heat.
