2
Clear the site of all large stones and rubbish from the surface.
Tip: If the area has sod, use a disk harrow to cut the sod for faster decay.
3
Break up and pulverize the soil as deeply as possible to increase water-holding capacity and root penetration.
Tip: Deep tillage helps plants survive during dry spells.
4
Break up remaining lumps and compact the soil slightly using a harrow.
Tip: Follow this with a hand rake for a final fine finish.
5
Construct the raised frame or mound the soil to be approximately six inches above the general ground level.
Tip: Raising the bed assists in warming the soil and ensures better drainage.
