When adding plants to your container garden, don't be afraid to gently pack them in. Try different placements, but remember that the violas are shorter than the pansies, so they'll probably work better on the outside of your container garden. Also, keep in mind where this container garden will go. Will only one side be viewed, or do you want to use it as a table centerpiece?
Once you're happy with how your plants look, add soil to fill the box. Make sure you get it in all the nooks, crannies and corners. Pat the soil down. You'll want it to be below the rim of the box to make watering easier.
