Fertiliser

How to Choose the Right Fertiliser

The best fertiliser depends on what you are growing, your soil conditions and whether you want nutrients to be available quickly or released gradually over time. General-purpose NPK fertilisers are suitable for many garden applications, while lawns, native plants, orchids, fruit trees and vegetables may benefit from more specialised formulations.

When choosing a fertiliser, consider the NPK ratio, nutrient release rate and the requirements of the plants you are feeding. Always follow the application directions on the individual product.

Granular NPK Fertiliser

NPK fertilisers contain the three major plant nutrients: nitrogen (N), phosphorus (P) and potassium (K). Granular NPK fertilisers are a popular choice for lawns, garden beds, vegetables, fruit trees and ornamental plants because they are easy to apply and are available in a wide range of nutrient ratios.

Our range includes general-purpose and specialised formulations, including Incitec Granulock Blue, Healthy Earth Organic Fertiliser and Campbells Rustica Plus. Browse our NPK Fertiliser collection to compare more options.

Slow-Release Fertiliser

Slow-release and controlled-release fertilisers gradually provide nutrients over an extended period. They are particularly convenient for pots, containers, garden beds and situations where regular fertilising is impractical.

Osmocote is one of the best-known controlled-release fertiliser ranges, with different formulations available for particular plants and growing conditions. Selected Osmocote products are purchased in commercial bulk bags and are also available from us in smaller quantities by the kilo.

See our Slow Release Fertiliser range for controlled-release and long-lasting fertiliser options.

Liquid & Water-Soluble Fertiliser

Liquid and water-soluble fertilisers are useful when nutrients need to be readily available to plants. Our range includes complete liquid NPK fertilisers, soluble fertilisers and individual nutrients for gardens, horticulture and hydroponics.

Popular soluble nutrients include calcium nitrate and potassium nitrate, while complete formulations such as Campbells Diamond Special T provide a broader range of plant nutrients.

Organic & Natural Fertiliser

Organic and naturally based fertilisers can supply plant nutrients while also contributing organic matter, minerals and other soil-improving ingredients.

Our range includes Healthy Earth Organic Fertiliser, Neutrog Seamungus, blood and bone, manure, worm castings and other organic-based plant foods.

Fertiliser for Native Plants

Many Australian native plants are sensitive to high levels of phosphorus, so choosing a fertiliser specifically formulated for natives can be important.

Our native plant fertilisers include specialist options such as Neutrog Bush Tucker, Earthlife Native Blend and Osmocote Low P. Always check the individual product directions and the requirements of the plants being fertilised before use.

Fertiliser for Flowers, Fruit & Vegetables

Flowering and fruiting plants require a suitable balance of nutrients throughout their growth cycle. Our range includes fertilisers for roses, orchids, citrus, vegetables, fruit trees and other flowering plants.

Options include granular NPK fertilisers, liquid and soluble fertilisers, organic-based products and specialised formulations for particular plants.

Browse our Flower Fertiliser, Fruit & Vegetable Fertiliser and Orchid Fertiliser collections to find more specialised products.

Lawn Fertiliser

Lawns generally require good nitrogen levels to encourage healthy green growth, together with other nutrients needed for strong roots and overall lawn health.

Our range includes granular, slow-release, organic and liquid lawn fertilisers suitable for popular lawn varieties including buffalo, couch, kikuyu, fescue and rye.

Popular options include Troforte Lawn Fertiliser and Healthy Earth Lawn Fertiliser. Browse our complete Lawn Fertiliser range for more choices.

Soil Improvers to Use with Fertiliser

Fertiliser supplies nutrients to plants, while soil improvers can help improve the growing environment and the soil's ability to retain moisture and nutrients.

Products such as zeolite, biochar, volcanic rock dust and other mineral soil amendments can be used alongside fertiliser as part of a broader soil improvement program. These products complement fertiliser rather than replacing the major nutrients supplied by a complete NPK fertiliser.
