Used little and often as a foliar spray or soil drench, it nudges the plant's own growth signalling: more photosynthesis, more sugar in the sap, better root establishment and a buffer against frost, drought and heat.\u003c\/p\u003e\n\u003cp\u003eThe name comes from Brix (°Bx), the refractometer reading for sugar in sap and fruit juice. Brix+ is not a primary fertiliser: nitrogen is 0.26% and potassium 1.65%, so it goes alongside a proper feed.
