1, buy lemons from the market, no matter what variety. Collect the leftover lemon seeds, put them in a small bowl, soak them in water, and change the water every day to keep the water free of impurities.

2. After soaking for seven days, a film on the surface of lemon seeds began to loosen.

3. Carefully remove the film and discard any rotten and soft seeds.

4. Find a pot (there is no hole in the bottom), add potted soil, and plant lemon seeds in it, with the bud tip facing down and the ass facing up, forming a concentric circle.

6. The surface is covered with a thin layer of medical stone, small black stone or other small stones. Water the soil back and forth three or two times, and you can wait for the green shoots to break through the ground.
