Greening and watering make the house on the first floor moldy. How is the property responsible?

It is not the responsibility of the property to make the house on the first floor moldy by greening and watering.

No, please remember that the property is not responsible for everything in your home. This belongs to the exclusive part of the owner. During the warranty period, both the developer and the construction unit are responsible. Outside the warranty period, you can only bear it yourself. But you can ask the property engineering department to go to your home to help find out what caused it.
