HAVE two trees, a pohutukawa and a rimu, that are in the wrong place.
They are not very big and I'm going to give them to a friend. Can
you please tell me when and how to shift them?
is a good time to shift them before they burst into spring growth.
The pohutukawa will shift easily as they have a very tolerant root
system. Rimu tend to have fewer roots so may suffer more shock.
The procedure is the
same for both. How much soil and root system you take will depend
on the size and height of the trees. As a guide, the diameter of
the root system you take should be 10 to 15 times the diameter of
the trunk. So if the trunk is 3cm in diameter you should take a
root system about 30-45cm across.
Use a sharp spade to
chop through the roots and lift the tree and root system, keeping
as much soil around the roots as possible. The depth of the root
system you take need only be about as deep as your spade. Wrap the
root system to prevent it drying out and keep it intact. Tell your
friend to replant the trees as soon as possible and to water them
well. They may need staking for the first year or so until the new
root system gets established, and watering over summer.
