Cold damage on orchids.   Frost and cold damage on Orchids. PART ONE .

     

 

 On Monday  the 3rd  July 2017  Melbourne had its coldest night in 30 years. Here at the nursery we recorded Minus 4  .

Stay tuned as ths blog will progress as more and more damage shows 

Damage is not a huge loss, as I was prepared and had all the nurseries igloos closed down tight. Unfortunatly and unpredictably most of the damage was on the orchids hanging on the barb wire strands up high. Why?, because they were closest to the frozen ice and frost on the igloo skins. Like standing too close to a radiator , but in reverse!! I though higher would be safer, but not the case.

Certain corners copped it worse than others, and plants in the centre of the igloos fared better.

Dendrobium hybrids with Kayla in their backgrounds copped it far worse than other natives with total bud and raceme collapse.

Sarcochilus as always hated it and developed watery leasions.Thank goodness 90% where in a seperate heated igloo made for |Sarcs in winter. 

We expect these negive 3-4.c nights once every 14 years or so and this one, like a good earthquake was overdue.
