How to Fertilise a Big Tree 

Back


How far do tree roots extend?

The roots of a big tree extend much further from the trunk than most people realise.

The roots can extend outwards more that three times the height of the tree itself, so a large tree in your yard may well be getting most of its nutrition from your neighbours’ yards and vice versa.

Scotts® Australia working with the environment

Environmentally responsible gardening

Osmocote®'s unique controlled release technology means there is no surplus fertiliser run-off or leaching to pollute waterways. Check out Scotts® environment stories.

What do you need to feed?

The most important feeding and water gathering roots are at the outer edges of the root zone and most of them are relatively close to the surface. The fine new roots do most of the work while the large roots are mainly there to anchor the tree.

What is the best feeding approach?

Use a controlled release fertiliser to feed your tree.

How do you apply the fertiliser?

Where's the dripline?

The dripline is an imaginary line drawn from the outer edge of the canopy of leaves to the ground.

  • Use a garden stake to make a holes about 20 - 25cm deep at regular intervals around the outer circumference of the root zone, outwards from the dripline.
  • Drop your fertiliser, such as Osmocote® Plus Trees, Shrubs & Citrus in a column into the holes.
  • Water the holes and the surrounding area well.

This will feed the tree for 6 months.
