I recently bought a Eucalyptus Gunnii from a local florist where I was
buying my daughter some flowers. Being transplanted from Australia
myself, I couldn't leave the poor sick thing languishing there.
However, it's not very healthy.
Most of the foliage is dead - dry, brittle leaves with no eucalyptus
smell. It has a few live leaves, close to the base of the trunk. The
sapling is about 60cm in height, and the trunk at its base is about
8mm. the trunk is brown to about 2cm in height from the soil, and is
green above that.
I wondered if it might not be weather damage - although the winter here
in the Czech Republic has felt mild to people, with temps being above
zero most days, our nights are still below freezing, sometimes to -10,
and we have had some constant cold winds.
The trunk itself appears to be quite healthy, but the leaves are grey
and dry, and some have a white powdery coating, which doesn't wipe off
(part of the leaf?), and the twigs those dead leaves were on are
blackened, but with the main trunk itself still remaining green. It's
quite hard to describe in words.
My main query here is whether to give the tree up (which I really don't
want to), or can I take some action to assist in its survival. Should I
give it a prune (and to what extent), can I give it any treatments that
might help, should I water, not water, give fresh air or keep in the
window, warm but in the sun, or something completely different. This
being the first eucalypt I've seen here in Europe's Armpit, I don't
think I can take it to a garden centre - mainly because they're pretty
rare creatures, but also because I don't speak the language! This
forum's help would be enormously appreciated!
