From China Daily:
Experts have started injecting nutrient-containing microelements like nitrogen and phosphorus into a 200-year-old ginkgo in the front of the former residence of Guo Moruo (1892-1978), a Chinese scholar and one of the leading writers of 20th-century China.
Following days of hot weather in Chongqing Municipality, over half of the tree’s branches and leaves dried and rotted for the lack of microelements. Actually, it is suffering from heatstroke, they say.
They are confident that the tree can be vitalized if it is rescued in time and treated properly.
I’m no tree scientist, but does this kind of thing really work?
