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

1L Concentrate
When to use


  • 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 biostimulants, fish and seaweed for larger, healthier plants that resist diseases and insect attacks
  • Feeds soils and plants by including a blend of seaweed and biostimulants resulting in lots of earthworms and soil microbes that build healthy soils and productive, vigorous plants
  • Can be applied any time of the year when plants are actively growing
  • World-leading innovation that feeds continuously for 3 months
  • It goes to work immediately and is effective whether applied to the soil or leaves



  • 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



  • 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


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
  3. The table is a guide for using the Concentrate in specific situations:


Plant Type Quantity How Often?
Seedings & Cuttings Mix 30ml (2/3 cap) in 9L water Apply every 4 weeks
Vegetables & Flower Garden Beds Pre-plant: Mix 50ml (1 cap) in 9L water Prepare the bed for planting then soak the soil
  Established Beds: Mix 100ml (2 caps) in 9L water Soak the soil around the planted areas

Potted Plants - Indoor & Outdoor Mix 50ml (1 cap) in 9L water Water pots with the mixed solution once every 4 weeks



  • Use any time of the year
  • Soil and air temperatures do NOT affect the release of nutrients so it can be used in winter to boost plants that are actively growing during the colder months
