Environmental conditions of the Chinese scholar tree's places of origin

The Chinese scholar tree likes light and is slightly shade-tolerant. It can adapt to relatively cold climates. Its roots are deep and well developed, and it is not demanding about soil. It can grow normally in acidic to calcareous and mildly saline-alkaline soil, and even under conditions with a salt content of around 0.15%. It is wind-resistant and also tolerant of drought and poor, thin soil, and is especially able to adapt to adverse urban environmental conditions such as compacted soil, but it grows poorly in low-lying waterlogged places. It has relatively strong resistance to pollution such as sulfur dioxide and smoke and dust. It grows relatively quickly when young, then grows at a medium rate afterward, and has a very long lifespan. Old trees tend to become hollow, but the dormant buds have a long lifespan, which is favorable for crown renewal.
