Building a waterfall out of pots and rocks can give you a wonderful design accent for either inside or outside your home. Outside, a rock waterfall with flower pots can add beauty to your garden. The soothing sights and sounds of running water will turn your landscape design into a peaceful paradise.
Position a large pot at the top of where the waterfall will be. It can be almost upright, if you wish the waterfall to cascade some distance into the pond, or it can be laid almost on its side to create more of a trickling, multi-tier design. The pot must have no holes or cracks. It can be propped up by dirt or rocks so it is higher than the pond level.
Lay a hose running from the outlet port of a submerged pond pump up to the top of the pot and rock waterfall. Secure the hose over the lip of the top pot so the water will run into it and fill it up.
Place smaller flower pots between the large top pot and the pond itself. Tilt each one enough so the water will spill over one edge into the next pot. Hold them in place with attractive rocks arranged naturally to the sides.
Break several large flower pots into halves to use in a more rustic-looking waterfall. Lay them down the slope of dirt like steps for the water to cascade down. Fill in spaces between them and support them with rocks of varying sizes.
Spray black pond foam between all pots and rocks in your waterfall structure. This will help to hold them in place and prevent the water from leaking down between the pieces and into the ground. Drop small pebbles onto any exposed pond foam before it cures to help hide it.
Turn on the pond pump at least 24 hours after the application of pond foam. Watch until the water is flowing down the waterfall made from pots and rocks. If it does not flow as you'd like it to, make adjustments or add more rocks or pot pieces to correct the flow. After drying it out again, more pond foam can also be added.
