This pond and it's surroundings are very natural and self contained. I really do not do much here at all. I mixed native and hybrids together that all like similar conditions and let them fend for them selves. One thing I did was to off set the bench a bit so you kind of have to look through some greenery to see the pond. It gives the whole a much more natural look, and more relaxing. For the fish it is better as well, they continue their lives much less disturbed. The biggest problem for me with this pond is servicing it. I had to create a walkway behind the pond so I can do what needs to be done, with out going into it every time. All said it truly is a relaxing place to enjoy a bit of time out. The most expensive thing I did was to set up lights for this. Underwater pond lights are expensive but well worth the effort, especially for the fountain it adds a bit of class to the whole. The Bronze Cranes are Fountains as well but I never use them that way.
Always remember no matter how natural the look, a back-yard pond is and it's surroundings are 100 % man made and needs regular care. Spend at least 2 hours a week on it. Or at least commit to that.
Last thing here always leave a lip of the Liner above the ground level. It may look ugly but it will prevent dirt and fertilizer and so forth from entering your pond. A fun thing here is to get creative and hide that liner edge. You see the liner by the walk way in this picture, however it is okay as it is structural and you would look past it into the pond.
