An artificial bog can purify water, filtering gray-water and runoffthat enhances its quality for fish, other animals and plants. A bog also gives the chance to grow quite a few colorful and intriguing plants. It might make a pond look bigger without dropping just as much water to nest within an open pond. The water from an existing pond also can be allowed to back into a bog.
Select a website for the bog at the border of the pond. An superb website is a place where water already flows into the pond. Mark out the region to your bog using flour. Pump enough water from the pond using a submersible pump or allow it to drain via a garden hose so that the water in the pond is at least 6 inches below its ordinary level.
Excavate the bog area to a depth of 2 feet 3 inches under ground level. Catch a ridge of soil between the bog and pond that is 3 inches lower than the pond’s normal water level.
Line the bog with 2 inches of sand. Cover the sand using a flexible pond liner. Drape the liner above the ridge of soil and into the pond. Use waterproof glue or waterproof tape to attach the bog’s liner and pond’s liner. Secure the liner edges, and disguise the liner by putting stones on it.
Fill the base of the bog using 1- to 1 1/2-inch round gravel to a depth of 6 inches. Cover that gravel with at least 6 to 12 inches of pea gravel.
Construct a barrier with rocks along the ridge between the bog and pond. Put a screen of 1/4-inch vinyl mesh on the back of the barrier.
Fill the bog with soil until it is level with the surrounding soil. Cover the soil with organic mulch, such as wood chips or shredded leaves.
Refill the pond. The water will flow over the barrier and into the bog. Allow the soil settle for a couple of days, then plant wetland plants in the bog.
