Demonstrate the consequences of changing soil pH by watching pink hydrangeas turn blue when Vitax Hydrangea Colourant 250g is added to the soil Read more
Details
Why we love it:
  • If your soil isn't acid, that blue hydrangea you planted will turn pink. Turn it back to blue by adding Vitax Hydrangea Colourant to the soil
  • It is formulated with iron and aluminium salts which acidify the soil to produce blue flowers
  • The colour change will be best with pale pink hydrangeas, with darker pink varieties turning to mauve or blue
  • Use it in the garden or in pots, and treat as a pH experiment to show kids what happens when soil pH changes

What you need to know:
  • 1 x Vitax Hydrangea Colourant 250g
  • Changes pink hydrangeas to blue
  • Contains iron and aluminium salts to acidify the soil
  • Use for both pot grown hydrangeas and those grown outdoors
  • Dissolve in a little hot water and mix with soil for best results
  • Apply weekly during growth
  • Always keep out of reach of children and wear protective gloves and eye protection where possible during use
