This balanced fertiliser with added organics will supply plants with both quick and slow release fertiliser. Easy to apply - just add one teaspoon per pot plant.. or 6 teaspoons per square metre of established gardens.
NPK refers to the main active ingredients in fertilisers. You can also have other ingredients like, Sulphur, Calcium, and Magnesium which this fertiliser has as well, but the most important ones are the Nitrogen, Phosphorous and Potassium - symbolised by NPK.
Because it does have Phosphorous you wouldn't use it on native plants as they dont like Phosphorous. Look for a labelled native fertiliser for that.
