Malted Barley

R40 - R1 080


Malted Barley is made from fresh ground whole grains and is used as a top-dressing for plants and soil.

It is applied by simply sprinkling on top of mulch, but a bit more frequently. Malted Barley can be applied to your grow every week or two. 


How It Works

Barley Grains are an exceptionally rich source of microbes, with a wide range of bacteria, filamentous fungi and yeasts colonizing the area between the husk and the pericarp. Many of the bacteria and fungi found on Barley Grains produce biologically significant levels of indole-3-acetic acid (IAA), a vital plant growth hormone that promotes cell division and is involved in the coordination and development of plant organs.

During the malting process the grains are made to germinate under strict conditions in order to facilitate the development of internally present hydrolytic enzymes. These enzymes catalyse the degradation of the starchy endosperm and cell walls of the grain in the presence of water, modifying the structure of the barley endosperm. Once germinated the grain is dried under conditions designed to prevent the denaturing of the enzymes

The key part of this process is the “peak enzymatic activity”. Basically, enzymes help plants do everything from photosynthesize, to more readily take up and make use of nutrients and minerals. The use of malted barley provides a lot of benefits and you really can’t go overboard with the product. It is very mild and will not burn your plants.

Once you have applied Malted Barley to your mulch, the worms within your grow bags will love it. They love to eat Malted Barley, and move it all around the soil for us. The increased worm activity also helps promote good aeration, even moisture retention, and nutrient cycling.



  • Barley introduces enzymes that makes nutrients more available to the plants
  • Rich source of microbes
  • Breaks down quickly
  • Super food for your worms


How to use

    Top dressing:

    • Apply 4 tablespoons (60ml) of ground malted barley to the base of a single plant (30L pot) and follow with a normal watering. 
    • Apply a heaped cup (280ml) per square meter (m²) for garden beds.
    • Can be applied every 1-2 weeks.

    Soil Amendment:

    • 30L of growing medium: Use 1.5 - 2 cups (420ml). 
    • Per 1L of growing medium: Use 1 tablespoon (10-15ml).


    • Use approximately 5kg ground malted barley per cubic meter (m³) of raw material.

    1L (approx. 650g)


    Helpful tips:

    When using malted barley, it is best used when freshly ground. Therefore, wait to grind the grains until the time of use. It can be ground into a fine powder in any sort of blender or food processor.

    After application, water as usual.
