Maintaining your pond is essential, and there are preventative as well as curative aspects. Putting in a pump, a cascade, water plants; cleaning and filtering… All of these contribute to the ongoing health and vitality of your pond.

Why bother maintaining your pond?

A pond left uncared for is doomed to deteriorate badly. On the other hand, you can keep it going strong by taking a few simple steps – for clean and clear water, thriving plants and healthy fish; in other words everything in beautiful harmony.


It's a fragile environment



A garden pond plays host to a fragile ecosystem which needs to be actively maintained in order for everything to stay in balance. There are several factors that threaten to upset this balance, starting with water stagnation. Stagnation encourages algae growth and the formation of silt. Oxygen levels decrease and the survival of any fish in your pond comes under threat.

In addition, excessive growth of certain aquatic plants can become a problem in itself, such as duckweed for instance. The same goes for an excess of fish, since their waste increases nitrate levels, promoting the growth of algae which bring down the oxygen level. Increased water temperature and evaporation in summer can also pose a risk.

These brief examples illustrate the fragility of the ecosystem in your pond, and show just how important it is to keep it well maintained. There are two aspects to pond maintenance: in advance, or when you first put the pond in; and regular maintenance once the pond is active, the regularity depending on the season and your particular circumstances.


Advance and ongoing maintenance


By taking a few simple steps when you first install your pond, you'll save yourself a lot of time in terms of ongoing maintenance. Here are some pointers:
  • careful choice of pond location; to avoid any nasty surprises later on, choose a shaded location away from any trees that shed a large quantity of leaves, seeds, etc.
  • installing a pond pump, essential to ensure adequate oxygenation by causing the water to circulate
  • installing a filter, letting you eliminate bacteria and algae through biological and mechanical action as well as removing impurities from the water
  • installing a UV lamp, which also acts to eliminate bacteria and algae, leaving clean, clear water for your plants and fish
  • putting in a cascade, to improve water circulation and oxygenation
  • putting in plants, since these fix oxygen into the water by photosynthesis
  • introducing appropriate fish species, in a manageable number, and avoiding notorious over-eaters like the grass carp

Regular housekeeping in your pond will let you maintain the right conditions for the flora and fauna you wish to cultivate. At the same time, it helps show the pond to its best advantage: a well-maintained pond is a true thing of beauty to have in your garden. To that end, here are a few essential tasks:
  • visually check the water level and clarity; if the level looks low – often the case in summer – you'll need to top it up, and if it's a little murky, you should check the filter
  • remove leaves and other waste vegetation using a landing net, particularly in autumn
  • regularly clean the filter, thereby avoiding letting it get clogged



  • keep any potentially invasive plants (e.g. duckweed) in check by removing the excess, and particuarly cutting back overstrong specimens. If you have plants in submerged pond baskets, make sure they're well filled and add more soil if not
  • monitor fish numbers and behaviour, as their size and health of your fish population is very important. A good rule of thumb is to maintain at least 50 litres of water per individual fish

For several years I have been running a garden service with a clientele of both individuals and companies. I manage a team of gardeners and ensure the creation and maintenance of green spaces. At the same time, I bring my expertise to my clients in terms of the maintenance and improvement of their gardens.

In fact, as a trainee and working in the hospitality industry at the beginning of my career, I focused on landscaping in a local community where I acquired solid technical skills through in-house training and the follow-up of major projects in a rapidly changing town.

On a personal level, I am equally oriented towards the art of gardening. With my wife, I created our garden from start to finish and I maintain it carefully, the same goes for the vegetable garden. As for DIYing, it’s not to be outdone. Yes, gardening is also tinkering: pergola, hut, pavement, fence, and so on...There is always something to do in a garden.

After working well together, my wife and I are proud of the result and delighted to be able to take full advantage of a friendly and warm environment. So, let us give you advice and help you in your choice of tools, maintenance, or improvement of your garden, nothing could be simpler.
