Double jeopardy for my daun kaduk and laksa leaves

With Sydney recording its coldest June morning since 1949 when temperatures dived to 4.3 degrees and the cold snap has terminally ravaged my collection of exotic tropical plants and herbs in the backyard. I begin to understand why farmers are always at the mercy of the weather. It is too late to blame myself for not bringing those precious herbs and plants (daun kaduk, turmeric, laksa leaves) indoor earlier. I have also learned, it is worth knowing a bit about how they grow and where they originally came from with their geographically origins as well as between species, so that you can extend the growing possibilities and provide adatation even where you live is outside geographical regions. It is so easy to overlook the climatic needs of these tropical plants and if you ignore its needs and not providing the conditions that suit them, you are likely to be disappointed like me.
In the meantime, I have salvaged the frost damaged daun kaduk and the laksa leaves by freezing them for future culinary use in the deep freezer.
