If you want to create a more formal-looking bed with 90-degree angled corners, use scrap wood for your garden outline. Lay two pieces of wood at each corner of your garden bed, placing the wood perpendicular to each other, and mark from there. Curved garden beds have more of a natural look. When planning, don’t overdo it on the size of your bed; you can always add on later if you want your bed to be bigger. After using one of the following techniques to outline your garden bed, don’t start digging right away. Instead, examine the outline from multiple angles and perspectives to ensure you’re satisfied with its appearance before you break out the spade.
The Stake and String Method
Plant stakes in the ground in your desired shape for a precise garden outline. Use a tape measure if you’re making your garden bed a specific size. Tightly wrap twine around the perimeter of the stakes. You can use tent pegs instead of stakes if you have them on hand. This method also works well to map out elevated elements of a garden bed, like a slope. To create a circular garden bed:
Break Out the Garden Hose
This is perhaps the most convenient way to outline your garden bed—no need to run to the hardware store for supplies. Simply grab your garden hose and use it to outline your ideal garden bed on your lawn. This method is helpful if you’re creating curves and arches in your flower beds. If no rain occurs, marks from the hose will be left in the grass, so you can easily remove the hose and start digging around the marks.
Paint Your Lawn
Another technique to outline your future garden bed is to use spray paint. Simply spray your lawn with the shape of your desired bed, using measuring tape or string as a guide. With regular lawn mowing, the paint will eventually disappear, but many home and garden stores offer grass-friendly, water-based paint that is washed away by rain. Editor’s Tip: Keep the paint away from hardscape elements like pathways or driveways.=
Powder It Down
Use a string or a hose to form your garden layout. Sprinkle sand or flour over the top to create the layout line, then remove the string or hose. The great thing about this method is that if you’re unhappy with your outline, you can simply wash the sand or flour away with water. Once satisfied with your garden outline, dig along the powdered pattern to construct your bed.
