Before your plants arrive, it is important to properly prepare the ground where they will be planted. If the border is grass, you will need to follow these steps:

1. Measure and mark out the width and length of the border where the plants will be placed.
2. Use a sharp spade to cut the turf into small, manageable sections for easy removal.
3. Slice off thin layers of the turf without removing too much of the topsoil. The removed turf can be stacked and left to decompose, creating a rich soil in a few months.
4. Use a sturdy fork to loosen and turn over the compacted soil, removing any large stones or debris.
5. Check the quality of the existing soil and add organic matter, such as compost, soil conditioner, or well-rotted manure, as needed. Mix it in with the soil using the fork.
6. Rake the soil until it is level and friable, ready for the new plants.
