Siting a Pond
After you have assessed your garden the next step is siting a pond. There are many factors you need to consider that help your ponds health.
Size of your Pond
The bigger the pond the better as they are easier to maintain. Water quality, oxygen levels and temperature will be less erratic and you are also less likely to have green water.
Unless you have a small garden where you have no choice as a large pond would look silly, you need to have good filtration systems in place and never overstock on plants or fish.
I promise that you will wish you had built a bigger one in time to come as you get so restricted with the level of plants and fish you can have.
Don't forget that depth is just as important as surface area so never make a pond less than 50cm deep and for larger ponds a minimum of 1.5metres if not more should be considered.
Algae loves shallow warm water and will thrive so the larger and deeper the pond the better.
The deeper the pond also helps when temperature rises or falls, it will provide healthy living for fish and other wildlife.
The sun provides energy to all your plants and fish but will also help algae growth in shallows. Too much shade and some plants will not grow or flower. Providing a nice balance is essential for a healthy pond. One good example is that lilies need sunlight but provide partial shade for the pond all day long which helps maintain water temperatures.
Trees may provide some shade but falling leaves that land on the pond can become hazardous towards fish. The leaves sink to the bottom of the pond and decompose releasing toxic gases. So stay away from trees when siting a pond.
Trees also grow huge roots that can spread the same length underground as the height of the tree above ground. These roots can rip through liner or cause cracks in concrete.
Other underground hazards could be pipes, drains or electricity cables and if you come across these then it is wise to stop and change the location of your pond.
Frost can damage pond liners, plants and if your pond is not deep enough kill fish. Having a bigger and deeper pond helps with the surface freezing completely over. Moving water also helps prevent ice.
The only way to help with frost when siting a pond is to try and position it on higher ground.
Siting a pond on sloping ground can be very attractive but requires a little more planning and work.
You need to dig into sloping ground and either have a barrier built to stop soil running into the pond or a retaining wall to hold the pond water in.
When siting your pond I would use flat or only slightly sloping ground.
