Tea bush is a tropical and sub-tropical plant and
thrives well in hot and humid climate which is
found in India ,Sri lanka ,Kenya, China, Japan
The ideal temperature for its growth is 20°-30°C
and temperatures above 35°C and below 10°C
are harmful for the bush.
It requires 150-300 cm annual rainfall
which should be well distributed throughout
the year.
Alternate waves of warm and cool winds
are very helpful for tea leaves
Tea gardens are set up on the cleared hill slopes
where shade trees are planted in advance. Seeds
are sown in the germination beds and the saplings
transplanted to the garden.
Kenya's lower land is too hot for tea to grow or
survive, so plantations are situated higher up at
elevations of 4,500 to over 7,000 feet.
Kenya is a fascinating, unique region and one of only
a few locations on the equator that maintains
glaciers.
The Rift Valley floor is far too hot and dry to grow tea, but in the highlands the
elevation and upland climate are perfect for vigorous tea growth.
India had a long tradition of being the largest
exporter of tea in the world, but her predominant
position as an undisputed leader of tea exporting
country has been severely shattered by fast
increasing domestic consumption.
Changing weather patterns in Eastern Africa are
increasingly being felt within agricultural systems not
only by policy levels abut also small farmers
the government of india improve the agricultural
system,drainage and clone old bushes into new
plants so more production could take place
the FAO created a two year project so
the tea cultivation of eastern africa could
increase
