Building a Beach in Garden
It is not a bad idea to build a sandy, muddy or stony beach together with one edge of the pond. It can give a striking feature to your garden. You can use pebbles, shells, and boulders to provide a shoreline effect. By assigning an adjacent part of the garden to shingle, where an upturned boat may be at permanent rest and placement of deck chairs and other such stuff can give a perfect landscape of beach. You can also reshape the garden shed to give it a look of beach hut.
Beach can be of any size, it can occupy the space as much as your pond space. In case you use a liner, you need to extend it to about a meter (3 feet) or more in a particular way. It is really not a good idea to create a beach surrounding the entire pond. This will not only occupy a vast space, but also look untidy.
For excavation of the beach area, always start from the farthest point from the pond. Starting from a vertical cut of about 25 cm (9 inches), going down towards the main area of the pond with a very slight slope. The slope should be angle at 45° while going down into the deepest part of the pond. The process of laying the liner is pretty much same for that of ordinary pond.
The only disadvantage of having a home-made freshwater beach is the developing of algae in the deep water. This is very rare in regularly washed seawater pools. However, this problem can be restricted by using any suitable algaecide periodically.
To build a muddy beach, you first need to build a retaining wall from old turfs. The wall should be quite solid with a desired height of 15cm (6 inches). The wall should be placed exactly 20cm (8 inches) back from the point of 45° slope. It is important to secure the turf wall by extending the bottom turf by one meter (3 feet). Now the next step is to fill the area between the turf wall and the vertical part of the liner with a profound clay loam (loam compost). Once the area is filled with loam, you need to compact it. Later rake it to level the far end of the pond with garden soil or lawn. Now what you need to do is to slope the compacted soil down towards the top of the turf wall. The slope should be slight throughout its way up to the top of the turf wall. Fill the pond now until the water level rise up to the turf wall. The water now begins to absorb in soil and give you a perfect muddy beach.
In sandy beaches, we don’t build turf walls rather we build a retaining wall for sandy beaches with stone, firmly secured with mortar. Sandy beaches usually expand beyond the vertical section of the liner. The sand in the beach is wet, but it gradually becomes dry towards the farthest point from the pond. However, the sand outside the liner pretty much resembling the surrounding soil of the lawn or garden, i.e. damp or bone dry.
With sandy beach, the selection of plants is important. The suitable choices may include ornamental grasses, with spiky yuccas, cordylines and phromiums forming the backdrop.
