Laying Out Curved Beds: Smooth Curves With a Hose or Rope
Laying out curved beds goes faster with a flexible line on the ground. Extension guides suggest a hose or rope to see the shape before you dig.
The short answer
Kansas State Extension says to outline the area with a rubber hose or heavy rope. Adjust curves until you have a large smooth curve that is easy to mow. Allow room for plants to reach mature size. Then cut a trench edge 4 to 6 inches deep with a sharp flat spade.
How do you lay out a curved bed?
Maryland Extension says to create a layout plan before building any beds. A simple map shows the space each plant needs. Kansas State Extension then says to outline the bed on the ground with a rubber hose or heavy rope.

How do you make curves look smooth?
Kansas State Extension says to adjust the line until you have a large smooth curve. Mowing around large curves is easy. Maryland Extension adds that every part of the garden should be easy to reach with paths plus room for hoses or carts.
Large curves: easy to mow. Smooth shape: clean bed line. Paths: reach every part.
How do you mark and cut the edge?
Kansas State Extension says use an edger or a sharp flat spade. Cut a trench or V shaped ditch 4 to 6 inches deep plus wide. Angle it toward the bed so grass roots struggle to cross. Illinois Extension says an edge 4 inches deep plus wide can easily contain bluegrass. Lift out soil plus grass to form a small cliff.
Spade cut: forms the edge. 4 to 6 inches: trench depth. Angle to bed: stops grass roots.
Troubleshooting
Wobbly curve: small hose bends. Pull it into larger arcs.
Grass crossing: shallow cut. Recut to 4 inches or more.
Crowded plants: bed too small. Allow for mature size.
