Yes, You Can Fertilise Native Plants! Native plants, like all living things, need nutrients to survive. If you have soil which is lacking in nutrients you will need to supplement with fertiliser. The truth is natives don't like manufactured or chemical based fertilisers that are high in phosphorous. But they do like to be fed, ideally in spring and autumn, either with a specifically designed Australian native plant food. OR an organic based fertiliser such as blood and bone- Great for all plants, including natives. No added urea. Blood & bone is one of the favourite fertilisers used by organic growers. Nitrogen is one of the three macronutrients (Phosphorus and Potassium are the other two) and is essential for vigorous growth.
