To arrange plants in a large container, follow these steps:
1. Choose plants of different heights and colors for variety.
2. Place taller plants towards the back and shorter ones in the front.
3. Fill the container with a good quality potting mix.
4. Create a focal point by using a centerpiece plant.
5. Arrange the rest of the plants around the centerpiece, ensuring they have enough space to grow.
By following these guidelines, you can create a visually appealing and well-organized container garden.
