Over thousands of years, Australian native plants have become accustomed to growing in our relatively nutrient poor soils. This means that many Australian native plants can be damaged by strong fertilisers.
It's still important to feed Australian native plants, as this helps promote attractive and healthy growth, but the choice of fertiliser is important. Yates Dynamic Lifter Soil Improver & Plant Fertiliser is rich in organic nutrients, that are released slowly and gently to plants, making it ideal for feeding native plants. Apply Yates Dynamic Lifter Soil Improver & Plant Fertiliser around the root zone of native plants each spring and autumn, and water in well.
Many Australian native plants will also look much better if regularly trimmed. After flowering has finished, prune shrubs like callistemon, banksia, correa, grevillea and melaleuca back by 20 - 30 % to promote a bushier and much tidier habit. Avoid cutting into old, leafless stems as plants may not produce new foliage.
Native plants like callistemon and lilly pilly can be prone to scale infestations. The disease sooty mould will often be seen in conjunction with scale. Scale can be controlled with regular sprays of PestOil. It's important to spray the scale directly on all sides of leaves and stems.
