What to do...
For established plants
Apply Osmocote at the dripline (below the outer edge of the
foliage) and outwards. Water well and cover with mulch.
For established pots
Sprinkle evenly over the surface of the potting mix. Water well
and top with a thin layer of mulch.
For self-watering pots
Make holes in the potting mix with a pencil or long skewer and
fill with columns of Osmocote. Water initially from the top and the
fertiliser will subsequently be diffused through the mix as the
water is absorbed from the well of water below.
For advanced trees
Use a narrow garden stake to make small deep holes spaced around
the circumference of the tree. Fill the holes with columns of
Osmocote and water the area well.
For potting up
Mix Osmocote with potting mix at the rate of 5g per 1
litre of potting mix.
Check first to see that the mix does not already contain

Broadcast Osmocote at the rate of 50-80g per sq m. The exact
rate will depend on the existing nutrient level of the soil.
For water plants
Incorporate Osmocote into the potting medium and top the pot
with gravel or pebbles.
