Choosing the Right Pot

Planting the Cassia Popcorn Plant

Before planting your cassia popcorn plant, water it thoroughly to ensure that the roots are moist. Then, fill the pot with the prepared soil mixture and create a small hole in the center of the pot. Place the plant in the hole and gently cover it with soil. Water the plant again to settle the soil around the roots.
