  • What is the best fertiliser for most plants?
At Pestrol, we recommend a balanced fertiliser for most plants, especially the acclaimed 10-10-10 mix. This balanced blend of nitrogen, phosphorus, and potassium ensures overall plant health, stimulating growth, root development, and bloom production.
  • What fertilizer should I use on my plants?
This largely depends on your plant type and its specific needs. Flowering plants, for instance, flourish with fertilisers rich in phosphorus. We proudly stock brands like Richgro, Brunnings, Yates, and Plant Needs that offer a wide range of fertilisers tailored to specific plant requirements.
  • What are the 3 main plant fertilizers?
The big three in the world of fertilisers are nitrogen (promotes leafy growth), phosphorus (enhances root development and blooms), and potassium (boosts overall plant health and resistance to diseases). You'll find these elements in various proportions across our product range to suit different plant needs.
  • What is 10-10-10 fertilizer in Australia?
The 10-10-10 fertilizer is a universal blend offering equal parts of the three primary nutrients: nitrogen, phosphorus, and potassium. It's a go-to choice in Australia for gardeners seeking an all-purpose fertiliser that caters to a wide variety of plants.   Quick Tips:  
  • For general gardening, consider a balanced fertiliser like the 10-10-10 mix.
  • Boost your blossoms with a high-phosphorus fertiliser.
  • After application, water your garden lightly to help the soil absorb the nutrients.
  • Moderation is key; too much fertiliser can be detrimental.
