Bogs are water formations that require both glaciers and hundreds of years to come into existence. A bog might not seem like an appealing addition to a home pond, but there are many flowers and other plants that survive well only in bogs, such as some species of irises, sedges and turtleheads. Not only are these flowers a joy to have, they also can block all views of your bog. You can create an artificial bog that do well as homes for all these different types of plants.
Dig 17 inches below the surface of your soil, and remove rocks from this bog area to protect the lining.
Lay a heavy layer of plastic in the hole. The plastic should be as wide as your bog, so the water will not drain out or away.
Create a mixture of 30 to 50 percent peat moss and 50 to 70 percent soil. For instance, if you have 50 percent peat moss, you need the remaining 50 percent to be soil. Peat moss holds moisture and provides an environment for healthy bog plant growth.
Add compost to your bog, which will provide nutrients for your plants and a healthy environment for good bacteria to grow. Good bacteria break down sludge and create a healthy nitrogen cycle for your bog plants.
Water your bog for 24 hours, turning the soil-peat moss mixture over with a pitchfork periodically to make sure that the peat moss is thoroughly soaked.
Plant your bog plants, and keep your bog evenly moist.
