Plant your seedling herbs at the base of trees. Place the herbs that require partial sunlight at various places around the trees in your yard.
Dig a trench in front of the hedges next to your house with a small gardener's shovel. Space out seedling herbs in this trench and cover the base of the plants with loose soil.
Install a row of seedlings behind your hedges. Keep them within 9 inches of the house to prevent spills from your gutter from drowning your herbs.
Cut treated 2-inch by 2-inch boards with your saw to build a frame 2 feet wide, 3 feet tall and 4 feet long. Hammer 8d nails into the lumber to secure the frame.
Lay a plastic tarp onto the frame. Fasten the tarp to the frame with a staple gun. Cut the excess tarp off of your frame with a razor knife. Plant your seedlings under the raised tarp.
