rose buds and leaves
are holes in the buds of my roses and irregularly shaped holes on
the ends and in the middle of the leaves. What can be causing this
and how can I get rid of it?
is likely to be either katydids
or New Zealand's native stick insect. The stick insects feed on
a wide range of plants from kanuka to manuka to roses, and they
do so with great gusto. They usually feed at night, so sometimes
you'll have to go out with a torch to find them.
The adult female drops
her eggs on the ground, and out of the eggs come her babies. They
will climb up the same rose as well, so in some cases you can have
hundreds of little baby stick insects, which all grow bigger, feeding
on your roses. Then you've got a problem.
So once you've got your
eye in to find these very cryptically coloured stick insects, all
you have to do is pick them up and take them to the park up the
road and release them in a nice native tree.
