On cold, grey days like these, we long for the heat of the sun and a glimpse of blue sky.
But tea plants are not like us; they like a bit of mist, and flourish in humid surroundings. They love it when the air is cool and visibility is reduced to a few metres. They are not so keen on a blue sky overhead.
I found this beautiful, rare, clear azure sky in Thiashola, in the Nilgiris mountains (India).
