Ice in the tropics
For those of you who doubt the veracity of those who say they occasionally add ice to their orchids to stimulate flowering, take a look at this photo of our garden, taken after a severe hailstorm. It was already several minutes after the hail had stopped falling and the ice was already beginning to melt - I was reluctant to go out and shoot during the storm itself as the marble sized hailstones were very painful and caused a lot of damage!
I hasten to add that this is not a frequent occurrence: it is only the second time in the 8 years I have been living here I can recall significant hail falling and of course it only lasts a very short time. - Ian.
