Osmocote® Plus Trace Elements: Fruit, Citrus, Trees & Shrubs

A no fuss, set and forget controlled release plant food for those who don't have the time or inclination to tend every plant or garden bed individually. The smart way to fertilise - one application feeds continuously for up to 6 months.

  • Two applications a year - one early Spring and another in early Autumn
  • Contains everything plants need for healthy growth
  • Releases nutrients at the same rate plants are able to take them up through the roots - no wastage or run-off into waterways and drains
  • Includes a wetting agent to help water and nutrients soak in to the soil

Boosted magnesium

To keep leaves green for longer, especially on citrus

Feeds when plants need it

The release of nutrients depends on temperature - more when it's warm and plants are growing and less when it's cold and growth is slow

Sustainable & environment friendly

Osmocote uses advanced prill technology that ensures even and controlled nutrient release with no wastage Controlled release mean feeding less often and more effectively; less frequent feeding is more economical and environment-friendly

Wetting agent

The added wetting agent enhances water absorption into the soil or potting mix and helps plants take up nutrients

Low phosphorus

Less than 2% phosphorus (the 'P' in NPK) means it can be safely used on most Australian native fruit trees such as Davidson's Plum, Finger Limes and Quandongs


500g, 700g, 1kg and 2kg tubs

Suitable for

Evergreen and deciduous ornamental trees and shrubs, shrubs, climbers, vines and grasses

Fruit trees including citrus, stone fruits, apples and pears, grape vines and berries

Potted foliage and fruiting plants including dwarf, espalier and columnar fruit trees

Safe to use on new plants - the controlled release of nutrients means it will not burn soft leaves or tender young roots

Not suitable for

Do not use in hydroponic growing systems, ponds or pots submerged in water

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

How it works

  • The release of nutrients from the fertiliser depends on soil temperature, not soil moisture
  • When the weather is warm in Spring, Summer and early Autumn, plants need more food and the fertiliser releases quicker
  • In Winter, when soil and air temperatures are lower, plants need less food because their growth rate is reduced, and less plant food is released

How to use

  • Use Fruit, Citrus, Trees & Shrubs throughout the garden to promote healthy growth, beautiful flowers and generous fruiting
  • Use the rates in the table below as a guide for how much to apply OR broadcast over beds using 50-80g/m2

Application Rates

Area Maintenance Transplanting
Trees & Shrubs 2 TBL per 30cm of plant height  15cm pot/bag = 3 TBL
Citrus Tree 10 TBL per mature tree 20 cm pot/bag - 3 TBL
Fruit Trees Years 1&2 6 TBL
Years 3 onwards 10 TBL
30 cm pot/bag = 5 TBL

Note: TBL - tablespoon = 15g

  • Lemons and other citrus have wide, shallow root systems so they need regular watering, feeding and mulching - keep the root zone clear of other plants & weeds
  • Established plants - sprinkle Osmocote in a band around the dripline on the soil (beneath outer perimeter of the leaf canopy) once a year and cover with mulch. This is where the feeding roots will be, not close in to the trunk
  • Pots - sprinkle at recommended rate over potting mix and cover lightly with mulch
  • Self-watering pots - make 10cm deep holes in the potting mix with a pencil or long skewer a few centimetres in from the rim of the pot and fill with columns of Osmocote. Water from the top once or twice to start the feeding process. The number of holes will depend on the size of the pot - as a guide, three equally spaced holes would be enough for a 20cm diameter pot.
