 For self-watering pots

  1. Make holes in the potting mix with a pencil or long skewer and fill with columns of Osmocote.
  2. 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

  1. Use a narrow garden stake to make small deep holes spaced around the circumference of the tree.
  2. Fill the holes with columns of Osmocote and water the area well.

 For potting up

  1. Mix Osmocote with potting mix at the rate of 5g per 1 litre of potting mix.

 Important: Check first to see that the mix does not already contain fertiliser.

For broadcasting

  1. Broadcast Osmocote at the rate of 50-80g per sq m. The exact rate will depend on the existing nutrient level of the soil.
