How to get rid of the small trees growing on the balcony wall, we must protect the wall.

1, the small trees growing on the balcony wall should be removed manually, and it is best to uproot them. The roots of many trees are difficult to grow into trees again, so it doesn't matter if there are residual roots; But some plants, especially herbs, may germinate, so try to root them.

2. Plants need soil for growth. Because there are holes, cracks and holes, there are many trees on the balcony wall. After years of dust accumulation to a certain extent, only seeds (such as bird droppings) grow. Therefore, removing the accumulated soil and sealing the holes, crevices and holes that can accumulate dust with cement can basically stop the growth of animals and plants.

If it is the wall root of the ground, it is necessary to remove the long small trees and pour a thicker concrete floor.
