Fertiliser Gladstone | Gladstone Garden & Landscaping Supplies

At Gladstone Garden & Landscaping Supplies, we are passionate about helping locals keep their gardens in the best condition possible. That is why we supply a wide selection of effective fertilisers and specialised soil conditioners.

Our fertiliser products help your soil maintain essential nitrogen, phosphorus and potassium, which naturally deplete over time. The conditioners we stock support healthy structure by improving aeration, boosting water holding capacity and helping the soil stay workable through changing weather.

How often should fertiliser be applied to garden beds?
Most garden beds benefit from fertiliser every six to twelve months, depending on the type of product used and how quickly your soil depletes nutrients. Organic fertilisers break down slowly and may only need topping up once or twice a year. Faster acting products might require more regular application. In warmer regions like Gladstone, soils can lose nutrients more quickly due to rainfall and heat, so checking plant performance and soil condition each season helps guide timing.
What is the difference between fertiliser and soil conditioner?
Fertiliser adds nutrients such as nitrogen, phosphorus and potassium to feed plants directly. Soil conditioner improves the structure of the soil itself. Conditioners boost aeration, increase water holding capacity and help the soil stay workable. Many gardeners use both together because fertiliser feeds the plants while the conditioner supports root growth and long term soil health.
Can soil conditioners help with poor drainage?
Yes. Many soil conditioners improve drainage by breaking up compacted soil and creating better pathways for water to move through. Adding conditioners to heavy clay soils or areas that stay wet after rainfall can help reduce pooling and encourage healthier root development. Blending them through the top layers of soil is usually the most effective way to improve overall structure.

Healthy soil makes a noticeable difference to how well plants establish and thrive. Our fertilisers and soil conditioners are chosen for their ability to strengthen root development, improve nutrient uptake and support long term soil structure. They suit everything from small garden beds to larger landscaping projects, giving you an easy way to boost growth without constant maintenance. Each product is formulated to work well in Central Queensland conditions and can be added to new or existing soil.

Whether you want better lawn performance, stronger flowering plants or a healthier vegetable patch, these products offer a simple path to better results. If you need help choosing the right option for your garden, get in touch with our team today.
