Collect the soil in separate utensils or containers, and dry out in the sun.
“We need thick clay for bonsai. If we keep its soil in polythene [bags], then moisture gets in and the soil starts breaking.
Add thick soil to the pot and then add other types of soil. Press all the layers hard with your hands. Do not fill the pot completely.
Place the bonsai plant in it. Add more soil and pat it down with the help of any wood.
Place the bonsai in a tub or bucket filled with water. After keeping it in water for three to four hours, place the bonsai in a shady location.
