Scotts Osmocote® Plus Organics Liquid Fertiliser & Soil Improver

An easy to use fertiliser that has the long feeding benefits of traditional Scotts Osmocote® but with the ease of use of a liquid fertiliser. It has added organics to boost soil and plant health and feeds the entire garden continuously for up to 3 months.

  • Liquid formulation delivers food straight to plant roots and continuously feeds for 3 months
  • Slow release which means there's no wastage of nutrients - they are used by plants as they become available
  • Easy to apply with Scotts Easy Sprayer - no drips, no hassles and simple On/Off tap on the handle grip
  • Ideal for all plants in any situation - garden beds, pots, vertical gardens, raised vegetable boxes, hanging baskets and window boxes
  • Also available in a 1L concentrate for application via a watering can

Slow release with the liquid advantage

Unlike most liquid fertilisers that give one instantaneous 'hit' of food to plants, this is a slow release formulation that not only releases nutrients over a three month period but also spreads and sticks to plants and the soil.

Contains soluble Scotts Osmocote® as well as bio stimulants, fish and seaweed for larger, healthier plants that resist diseases and insect attacks

Feeds soils and plants

Includes a blend of seaweed and bio stimulants resulting in lots of earthworms and soil microbes that build healthy soils and productive, vigorous plants

Use any time

Can be applied anytime of the year when plants are actively growing

World leading Aussie invention

World leading innovation that feeds continuously for 3 months

See 'How it works' section for more information.

Hose-on or Concentrate

The 1L Easy Spray bottle is perfect for small gardens, quick fertilising tasks and covers up to 180m2


The 1L Concentrate is the better option for large or difficult to reach areas where a watering can or pump sprayer may be easier to use. It makes up to 300L

Handy Tip: To determine the size of your garden, multiply the length x width in metres. 1 long stride = approx. 1 metre

Leaf and root uptake

It goes to work immediately and is effective whether applied to the soil or leaves

Suitable for

All trees and shrubs including natives and other phosphorus-sensitive plants - it has zero phosphorus content

All flowering and leafy annuals, perennials, climbers and groundcovers

All vegetables, herbs and fruits

Potted plants including vegetables, herbs, palms and indoor plants

Safe to use on new plants in the garden or in pots indoors or out - its gentle slow release formulation will not burn young leaves or roots

How it works

  • Unlike most liquid fertilisers which are readily washed off plants, it contains an innovative and advanced form of nitrogen which binds to leaves, stems and soil particles and will not wash off once dry
  • It's boosted with organics (bio stimulants, fish emulsion) that activate soil micro-organisms, condition the soil and enhance nutrient uptake
  • It also contains seaweed extracts that: 
    • Increase yields
    • Promote hardy root growth ensuring strong early plant development
    • Enhance nutrient uptake
    • Assist in stress resistance and quick recovery from trauma
