Weak plants are subject to blight. After it got blight, it gets weaker.
For example, if a plant that requires full sunlight grows under weak sunlight,
or a plant requiring high humidity grows under very dry place,
or a plant got broken off frequently, the immune system of the plant becomes
weak, the cell wall becomes thin, and pests can bite them easier.
Blights that can attack fig trees can attack bodhi trees too.
