How about planting poplar trees outside the yard?

Poplar trees are generally tall and straight, blocking the sunlight in the yard, which is not conducive to the volatilization of Yin Qi. If you want to lift poplars, it is usually in the north, because in geomantic omen, the north is respected. It is better to lift big trees, not short ones, such as peach trees, in the east. Houses usually face south, and the yard is filled with poplars, so the sun is blocked.
