Dear Rabbi,

Could you please tell me about the ancient practices regarding tree-planting and the birth of a son and a daughter?

In Talmudic times, when a boy was born they planted a cedar tree; when a girl was born they planted a pine tree. The poles of the wedding canopy were made out of the wood of the trees that were planted at the birth of the bride and groom.
