The number and size of the rocks you use for waterfall are one of paramount importance in creating outdoor waterfalls.

There is nothing as soothing as hearing the sounds of falling water as you sit outdoors on a summer’s evening. Outdoor waterfalls in the garden do not have the thundering roar of the large waterfalls you find in exotic locations of the world, but they can certainly help you create an exotic ambiance. This structure will create an oasis of peace and comfort that you will long to come home to at the end of the day.
If, when landscaping, you have rocks that you want to have taken away, these may be the perfect ones for the outdoor waterfalls because they are natural for the environment.

Gravel and pebbles are also vital for outdoor waterfalls. You need to use these as the lining of the structure and to fill in gaps between the large boulders so that there are no visible spaces between them. Algae does not form as readily on large boulders and by using them in combination with gravel and small stones, you will have fewer algae problems to deal with.
Boulders are accent pieces for outdoor waterfalls. Although they are difficult to handle and maneuver into place, you do need to have them placed at varying intervals to create a natural look at the top or the bottom of the waterfall. You don’t need to have the whole boulder showing. Bury about one-third of the boulder so that it will remain firmly in place.

The speed at which the water flows over outdoor waterfalls also determines the sound. When you have a large amount water rushing rapidly down to the bottom the sound will be quite loud, particularly if you also include old world wall fountains or any other type of large water feature.
