I have been growing bonsai in the same area of
Sydney for the past 7 years, but I’ve never seen my trees to be exposed to
sub-zero temperatures. This morning I found frost on some of the leaves and ice
in the drip trays. The lowest night temperature for my area was reported to be
6°C and at the time of taking the photos shown above the temperature was
reported to be 18°C. A disparity of 20 degrees! No wonder everybody thinks
there is global warming.
