What is it?
Fruit color comes from pigments that develop as fruit ripens, while brix (sugar content) reflects the sugars the plant produces through photosynthesis and moves into the fruit. Both depend on healthy leaf area, good light, balanced potassium and micronutrients, and avoiding stress late in the season. Shortfalls in any of these leave fruit dull and bland.
How to identify it
- Dull, pale, or uneven fruit color at maturity
- Low measured brix and flat, less-sweet flavor
- Fruit that doesn't reach its variety's full color potential
- Often linked to weak late-season leaf health, low potassium, or stress
Damage and how it spreads
Poor color and low brix reduce market value, grade, and consumer appeal, and signal that the plant isn't finishing fruit to its potential. Because these traits depend on late-season plant health and nutrition, a targeted finishing program can meaningfully improve both quality and returns.
How to control it
- Maintain healthy late-season leaf area and good light exposure on fruit.
- Balance potassium and micronutrients that support sugar and color development.
- Avoid late-season stress and excess nitrogen that delays ripening.
- Use finishing inputs to enhance color and brix as fruit matures.
Recommended Vegalab solution: Color Boost
Vegalab Color Boost is a natural fruit and flower color enhancer that lifts color at finishing. Brix Boost is a natural sugar and brix enhancer for sweetness, and Potassium Pro (P-K fruit and flower fertilizer) supports the potassium that drives color and sugar movement. Use as a late-season finishing program.
| Role | Product | Use |
|---|---|---|
| Primary correction | Color Boost | Fruit/flower colour enhancer |
| Plant support | Brix Boost | Sugar / brix enhancer |
Preventing it next season
Protect late-season leaf health, balance potassium and micronutrients, avoid late nitrogen and stress, and finish with Color Boost and Brix Boost as fruit ripens.
