HortiBoost takes plant nutrition beyond conventional fertilisers by combining a unique, powerful package of 20 essential amino-acids, humic acid complex, seaweed and also major and minor nutrients from organic and inorganic sources.

HortiBoost is fast-acting, with absorption into the crop within 12 to 24 hours while facilitating maximum utilisation of nutrients, water, CO2 and light to maximise growth efficiency.

HortiBoost can be used alone as a biostimulant or tank mixed with a wide range of Hortifeeds soluble fertilisers and HortiPhyte products.

HortiBoost contains good levels of trace elements, especially iron, and low levels of the major NPK nutrients.
For a stronger NPK gift, HortiBoost is compatible with HortiMix soluble and liquid fertilisers and the HortiPhyte range. HortiBoost can be added to tank mixes with HortiFol fertilisers for foliar application and with HortiMix fertilisers for fertigation application.

Can be used on a wide range of crops including:

  • Fruits
  • Vegetables
  • Salad crops
  • Vines
  • Plants in propagation
  • All ornamentals
