2. Measure the area and mark the corners with paint or flour. Connect the dots to form the bed perimeter (figure B). Remember, if you don't like the way the bed is shaping up, change it. 3. To make grass extraction easier, edge the border of the bed with a shovel (figure C).
4. Use a shovel to dig out the grass inside the perimeter.
5. If you want to create a ground-level bed, all you need are topsoil and plants. Proceed to step 10.
6. For a raised planter--which is more interesting, changes the elevation and improves drainage--line the bed with moss rocks, alternating big and little stones. If the rocks are heavy, get some help and wear protective gloves.
7. Once the perimeter is complete, score the soil by digging and turning it with a shovel.
8. Add about four to six inches of new topsoil to the bed and spread it evenly with a rake. Be sure to fill in the spaces between the rocks.
9. Create a second row of rocks along the interior edge of the first row.
10. Select plants according to color, blooming cycle, growing characteristics and requirements. For instance, if the flowerbed is located in full sun, make sure all the plants tolerate full sun and share similar watering requirements.
