I have planted one green tomato tree around 2020 February and it was growing well by my observations but now after almost 2 months i have seen the tree branches start to drying like this ( maybe could not be seen in pics but could be sensed by pressing the new leaves and seeing that they are dried!!):
And more pic like this:
So my place is in some near dessert situation by this weather :
Also give it almost 2 litter of water for every day.
So i like to know your opinion about the reasons and treatments.
