have several hass avocado trees in the north. We have a problem
with hares and possums are there deterrents that we could
use that will not affect the trees' production or fruit quality?
The trees are shallow rooted other than a shelter break,
are there other things we can do to help support the trees as they
grow so they do not blow over in gails and such?
is a product used to deter possums. It is known under several names
Thiroprotect, Thiropel or Thiram. Some garden centres stock
this product, otherwise you could try one of the large stock firms.
I have heard spraying trees with liquid sheep manure as a foliar
feed is an effective deterrent.
Avocados have a long
tap root. Trees can become weakened if this tap root is damaged
at some stage from the seed germinating to planting. This leads
to trees being easily blown out of the ground. Avocados require
good drainage, being very intolerant of wet feet which can lead
to root rot disorders. The best thing you can do is establish a
good shelter belt around your trees.
