Garden ponds are popular additions to landscaping. Garden ponds come in a variety of sizes depending on how elaborate you want your pond to be. However, you can build an inexpensive garden pond that will be just as beautiful as the larger, more elaborate ponds. Build the pond as large as you want it to be and as your space allows. It is easier to have the right size in the beginning because you will not be able to extend it should you decide later that you want it larger.
Decide on the size of the pond and the area where you wish the pond to be. Make sure you only make the pond as large as you are able to maintain. Build your pond near the home and an electrical outlet.
Use the water hose and lay the hose in a shape you would like your pond to be. For instance, if you want a kidney-shaped pond, lay the hose in a kidney shape. This gives you an idea of what your pond will look like and how big it will be. Move the hose around into different shapes until you find one you like. Spray the white spray paint directly onto the ground to give you a pattern from which to dig. Remove the hose and you will see your pattern.
Excavate the area inside the white paint. Ponds need to be at least 18 inches deep, but preferably 2 to 3 feet deep. Leave some areas of dirt after 9 inches to create ledges for potted plants. Slope the bottom of the pond toward one end so debris will collect in one spot for easier cleaning. Remove all roots, rocks and other debris from the sides and bottom of the pond.
Lay the pond liner inside the pond with about 3 feet over the sides. Smooth the liner as well as you can to remove all wrinkles. It will be necessary to make folds along the sides so the liner will fit snugly in the hole. Stack different-sized rocks around the edge of the pond to hold the liner in place or use bricks. Make sure the rocks and bricks are fitting snugly against one another. Cut the liner on the outside of the rocks to remove excess liner.
Install the pump in the bottom of one end of the pond closest to the electrical outlet. Use an outdoor extension cord if needed. Add a small amount of water in the bottom of the pond so the pump will circulate it to clean the water. Once the water is clean, fill the pond with water and let the pond circulate approximately one day before adding plants and fish.
