Brix Boost
Last updated:
Brix Boost is a high-phosphorus, high-potassium foliar fertilizer that raises fruit sugar levels and flavor. It drives sugar synthesis and translocation, with brix typically rising within 7–10 days of application and improvements in flavor, firmness and shelf-life.
Liquid fertilizer concentrate — Raises Brix, Improves flavor.
Liquid fertilizer concentrate from Vegalab Crop Science, powered by P, K, Mg + stevioside, xylose, trehalose, mannitol. Brix Boost targets Brix increase, flavor enhancement, fruit quality.
High-phosphorus and potassium foliar fertilizer that drives sugar synthesis and translocation. Brix levels rise within 7-10 days of application; fruit flavor, firmness and shelf-life improve.

Why does brix matter?
Brix — the measure of soluble sugars in fruit — drives flavour, market grade and often price. Higher brix means sweeter, more flavourful fruit that also tends to store and travel better. For grapes, berries, melons and stone fruit, lifting brix in the final weeks before harvest can be the difference between average and premium fruit.
How does Brix Boost raise sugar and quality?
Brix Boost (0-13-5) combines phosphorus, potassium and magnesium with natural sugars (stevioside, xylose, trehalose, mannitol). Phosphorus and potassium drive the synthesis and translocation of sugars into the fruit, so brix typically rises within 7–10 days of application, alongside gains in flavour, firmness and shelf-life. The magnesium supports the photosynthesis that ultimately supplies those sugars.
When and how should it be applied?
Apply as a foliar spray during fruit development and ripening at 1:1,000–1:500 (1–2 mL/L). Timing it to the sugar-accumulation window — typically the final development and ripening phase — gives the clearest brix response. One to two applications through this window is usual.
Which crops is it for?
Brix Boost has been tested on grapes, melons, berries, stone fruit and citrus — crops where sugar content and flavour directly determine quality and value. It is especially relevant for premium and fresh-market production where eating quality is the differentiator.
How does it improve shelf-life and firmness?
Alongside raising sugars, the potassium and balanced nutrition in Brix Boost support firmer fruit with better post-harvest behaviour. Firmer, higher-quality fruit handles transport and storage better, so the benefit carries from the field through to the shelf.
