There is a maple leaf tree near the grave, which is more than one meter away from the grave. Is this good for the servant?

If there is no forest around, just a maple tree will be fine.

If there are trees around, it is not easy to plant trees at a distance of one meter. Maple trees are tall, and the crown covers the grave. The hue is too strong. It is an invasion for roots to drill into graves. There are many leaves, which all affect Feng Shui.

If there are trees around, cut them down.
