Cut and place the landscape fabric over the entire bed. Use landscape fabric ground staples to hold it in place while you work.
Arrange the plants in their pots on top of the landscape fabric. Step back and make sure the arrangement works and looks good. Avoid overcrowding and read all plant labels to make sure they are placed in the appropriate light type.
Using a utility knife, cut an X into the landscape fabric where each plant is located and dig a hole appropriate to the size of the plant. Remove the plant from the pot, loosen the roots by hands or with the utility knife and then place it in the new hole.
