Avoid using heavy soil, as this can cause issues with drainage and wet feet.

When you’re ready to pot your Petunia, fill the pot with the soil of your choice and make a small indentation in the center. Gently place the Petunia inside, and fill the sides with soil and cover the roots. Firmly press the soil down, until the plant stands upright. Finally, water it thoroughly with lukewarm water.
