What feng shui tree should be planted behind the house?

Peach willow is planted in the east, gardenia elm is planted in the west, plum dates are planted in the south, and apricots are forbidden in the north. There are trees in the middle door, rich mountains and three elms behind the house, and ghosts are not close. It is immoral to have apricots in the east, plums in the north and peaches in the west. People like to plant double dates in front of their doors, and bamboo and trees all around make money.

As the saying goes, there are willows in front of the door, pearls and agates go home, trees in front of the door, and gold and silver go home. There are apricot elms in front of Huaizao, persimmon in the east and honeysuckle in the back, pine, bamboo and plum in front of Guiting peony are cold-resistant, creepers are on the screen, and thorns are in front of doors and windows of gold, silver and chrysanthemum, which are not things in the palace. Remove the lilacs, leaving Jin Lan's small peach blossom, as red as fire, and the moon.
