Description

Sharper flower quality from an organic potassium correction

Canna Organic Potassium is a 20% potassium (K2O) mono nutrient made to lift both the quality and quantity of the flower. Potassium strengthens the cell wall, raises stress resistance and drives the production of proteins, carbohydrates and bloom, while regulating water and nutrient transport. As an organic, chloride-free product, it suits growers on organic or low-input programmes who still want a precise way to correct potassium.

Key Benefits

  • 20% potassium (K2O), chloride-free, for targeted correction
  • Organic formulation suited to organic growing methods
  • Strengthens cell walls and boosts resistance to stress
  • Improves protein, carbohydrate and bloom production
  • Regulates water and nutrient transport through the plant

Potassium deficiency dulling your flowers?

Low potassium weakens cell structure, lowers stress resistance and leaves flowers under-developed, since potassium underpins so much of the plant's transport and carbohydrate production. This organic mono nutrient targets that deficiency directly for stronger, better-finished bloom.

How to Use

  • Standard rate: 1–2ml per litre (10–20ml per 10L, 1:1000 to 1:500)
  • Use the higher rate to correct a clear deficiency, the lower rate to support bloom
  • Do not mix in concentrated form with calcium- or magnesium-containing fertilisers – add separately within the schedule
  • Introduce gradually, then check and adjust pH after mixing
