Potassium Pro
Potassium Pro is a high-potassium, high-phosphorus fertilizer that drives fruit and flower development. Potassium regulates stomatal function, sugar translocation and protein synthesis, so balanced K and P support stronger fruit set, better sizing, higher brix and improved stress tolerance through the reproductive stages.
Potassium Pro is a high-potassium, high-phosphorus fertilizer formulated to drive fruit and flower development. Potassium regulates stomatal function, sugar translocation and protein synthesis, so balanced K plus P supports stronger fruit set, better sizing and improved stress tolerance through the reproductive stages of the crop.

Why is potassium the key fruiting nutrient?
Potassium is the nutrient crops need in greatest quantity during fruiting. It regulates stomatal function (and so water use), drives the translocation of sugars into fruit, and supports protein synthesis. When potassium is short during the reproductive phase, fruit size, firmness, sugar content and stress tolerance all suffer.
How does Potassium Pro work?
Potassium Pro (0-20-26, from mono-potassium phosphate and potassium chloride) supplies potassium and phosphorus during fruiting. The potassium drives sugar movement, water regulation and firmness, while the phosphorus supports the energy transfer behind fruit development. Together they support fruit set, sizing, brix accumulation and stress tolerance when demand is at its peak.

Always read and follow the applicable product label.
Apply foliar or through fertigation during fruit development and ripening, timed to the reproductive stages when potassium demand peaks. Concentrating applications in this window gives the clearest effect on sizing, firmness and sugar accumulation, rather than spreading potassium thinly across the whole season.
Which crops is it for?
Potassium Pro has been tested on tree fruit, grapes, berries and cereals - crops where fruit quality and grain fill depend heavily on potassium during the reproductive phase. It is a core late-season nutrition tool for premium fresh fruit and high-yield cereals alike.
How does it improve stress tolerance and quality?
By regulating stomatal function and water use, potassium helps crops cope with heat and water stress during the sensitive fruiting period, while its role in sugar translocation lifts brix and eating quality. The combined effect is fruit that is better sized, firmer, sweeter and more resilient through to harvest.
