How to Increase Brix in Tomato

For flavour-market and processing tomatoes, Brix is a paid-on spec. Over-watering, heavy loads and weak canopies dilute sugars and cut flavour, while balanced crops finish sweeter and richer.

Common crops affected

Why it matters

Brix drives flavour, grade, and price; it's built by healthy photosynthesis plus potassium and finishing nutrition, so two blocks of the same variety can differ widely.

When it appears

During fruit development and ripening — the finishing window.

What drives it

  • Photosynthesis and canopy health
  • Controlled irrigation late-season
  • Potassium and sugar-loading nutrition
  • Load balance and ripening timing

How to manage it

  1. Protect late-season leaf health; supply potassium; avoid late nitrogen.
  2. Apply Brix Boost with Potassium Pro through ripening.

Recommended Vegalab program

Brix Boost — encapsulated nutrition supporting sugar accumulation during ripening.

Results you can mention: in a cherry-tomato trial, Brix Boost raised fruit sugar by about +2 °Brix versus untreated (reaching ~6 vs ~4 °Brix) and fruit ripened earlier; in field trials Charge BioBoost also lifted soluble solids (roughly +0.4–0.6 °Brix) alongside yield.

Apply from early ripening on the label interval; ease late irrigation to concentrate sugars where crop-appropriate.

Product claims, rates, and availability vary by jurisdiction; always follow the applicable label.

Frequently asked questions

Does cutting water raise Brix?

Moderate late-season deficit can concentrate sugars, but too much stresses the crop — combine careful irrigation with Brix Boost.
