    *compared to other liquid fertilisers in Australia 2016

Liquid advantage

Unlike most liquid fertilisers that give one instantaneous 'hit' of food to plants, this is a slow release formulation that spreads and sticks to plants and the soil.

Feeds soils and plants

Includes a blend of 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

Hose-on or Concentrate


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


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 450L

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

Boosted iron & magnesium

These elements keep citrus leaves deep green and promote lush growth of other trees and shrubs

Suitable for

All trees, shrubs, climbers and vines including Australian natives - it has no phosphorus

All citrus and fruiting trees and shrubs, including vines and berries

Potted fruiting and ornamental trees and shrubs

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

Not suitable for

Do not use on lawns - use only specifically named fertilisers on grassed areas

How it works

  • Unlike most liquid fertilisers which are readily washed off plants, Osmocote Plus Bio Stimulants contains an innovative and advanced form of nitrogen which binds to leaves, stems and soil particles and will not wash through the soil once dry
  • It's boosted with bio stimulants that activate soil micro-organisms, condition the soil and enhance nutrient uptake

How to use

Easy Sprayer

  1. Shake the bottle well before attaching to the hose - ensure the thumb switch is in the OFF position first
  2. Tighten the hose connector on the handle prior to connecting the hose; turn the hose tap on
  3. Slide the thumb switch to the ON position to FERTILISE or slide to the WATER position to just water your garden
  4. Walk slowly using a sweeping action to evenly distribute the spray over the measured garden area (the bottle should empty in approximately 12 - 13 minutes
  5. When finished, switch to OFF position and turn the water off

When using the Concentrate:

  1. The 1L Concentrate comes with a measuring cap that will dispense 30-50mL , the amount required for 9 litres of water
  2. The concentrate can also be used in a pump sprayer. Use the same dilution rate as for the watering can
