Maintaining your garden pond

There are several garden pond weeds that need to be kept under control and if left can cause chaos in your pond.

The most common weeds found in a garden pound are blanket weed, duck weed and algae. Although small amounts of these weeds are essential for plants, fish and insects to live in the pond, they can completely take over the pond if left for a short period of time and will eventually kill any plants you may have in or around your pond.

To keep these weeds in check, you need to ensure that there are other plants which allow the nitrogen fertiliser to get into the water which will prevent any build up of the unwanted weeds. These plants that can be used to control the weeds are called marginal plants, which you can find in most good garden centres.

However, if this fails to prevent the spread of the weeds, they can be easily removed by hand. Blanket weed in particular is very easy to remove from your garden pond and it will usually come out in large batches.

Similarly, duck weed can cover a small pond in a short space of time and can be removed by hand using your hand or a small sieve, ensuring that you take the small roots out of the water when removing the leaves.

Digging a garden pond

Garden ponds can add so much to a home. The sound of the water is so relaxing on a peaceful afternoon and the pond life that they attract can be hugely educational to the children.

But building a pond is not as straight forward as you might first think. It’s not a case of simply digging a hole and turning on the hose.

The first stage is to make all of the important decisions. Do you want a liner pond, where you get to choose the size and the shape of the pond? Or would you prefer the pre-form style?

Deciding on any pumps, waterfalls and filters that you may need is also a good idea in the early stages, as this means you will be able to dig channels for the wires and pipes as you go along.

Once the hole has been dug, it should be filled with a layer of sand or wet newspaper. This will protect the liner from moulding. You will then need to check that the top surfaces are horizontal to ensure that the water level looks right once it is filled. Do this by placing a plank of wood across the pond and placing a spirit level on top of this. This process can be a little tedious as it can be a case of trial and error to attempt to get the measurements correct.

After this, you can add the moulded pond or liner and finally the water. Job done.

Cleaning and sludge and silt removal in garden ponds

One job that most pond owners will have to face at some point in their pond owning lives will be thoroughly cleaning the pond. Doing anything that is so invasive will undoubtedly alter the balance of life in the pond, so any dramatic cleaning procedure should be avoided until it is absolutely necessary.

The ecosystem in your pond may have taken years to establish so if you remove all the plant and animal life (and of course all the water) you will be lucky if you do not have a few teething problems afterwards. Regular maintenance is the key, and if you use pond maintenance products such as a heavy duty pond vacuum and own items such as arms length pond gloves and pond waders you will be more likely to maintain your pond more regularly. It goes without saying that if you do some of the dirty work on a regular basis your pond life will appreciate it in the long run.

Pond vacuums come in hand powered and electric powered models and are a better solution than the methods used years ago that usually involved a bucket and some very hard work.

Pond maintenance and a balanced ecosystem

Garden ponds offer a diverse ecological environment where many life forms take residence over the years. If the pond is healthy and is self supporting then the organisms that live there should be able to maintain a balanced environment. If however your pond does not have a balanced ecosystem then waste products will build up.

If you are lucky you will never have to try to chemically or physically readdress the balance of your pond because the organisms that live there should do it for you. Fish however produce large quantities of waste products including ammonia, which if not dealt with can actually poison life in the pond. Also over time the pond may silt up due to the deposition of these waste products and other organic products such as decomposed plants, leaves that may have fallen into your pond and uneaten fish food.

There are things that you can do to tackle these problems including adding pond treatments to introduce friendly bacteria into the pond. These may help to restore the natural balance of the pond or may tackle specific problems if they occur. Most pond equipment suppliers will be able to help you with specific questions you have regarding the pond water quality and many will be able to offer you solutions to these problems.

Add a water feature to your garden

A garden pond can be a beautiful addition to anyone’s home, the sound of trickling water and the tranquillity the pond can add to your garden can calm the senses and provide a beautiful backdrop to outdoor eating or entertaining.

A garden pond can fall into many categories, from purely a water garden that is setup to support minimal life to a large formal pond containing Koi. If you have little space and just want to create a feature and a pond would just not fit there are however other options available.

There are many off-the-shelf products available that can give you a water feature in your garden. This could be a standalone water container with some sort of pump creating a waterfall effect, it could be water falling down a sheer face creating a wall of water effect or could be just water falling from a tap into a receptacle and then being pumped back to the tap. You can even get small submerged pools that are covered with decorative stones with a fountain rising from the centre creating an amazing decorative effect.

Whatever option you choose it will add that something special to your garden. Remember however that these small containers and fountains are not suitable for supporting fish life and should only be used for decoration.

Pond Health and a New Pond

So you have designed and built your pond, filled it with water and checked the pump and filter system is working. You have also left the water for a few weeks so that it will stabilise and the eco-system will start to evolve. Now you are ready to give your fish a new home.

Choosing the type of fish for your pond can depend on a lot of things, are you building a decorative large pond that will be capable of supporting Koi? Do you just want a few goldfish? Are you interested in other types of coldwater fish that may need more time and attention?

When you add the fish to your pond be sure not to overstock it, especially if you choose Koi as the fish will need plenty of room to grow and hence need larger dissolved oxygen levels. Goldfish are a form of lowland Carp that is suited to living in garden ponds because of their great resilience to poor living conditions so may be a good choice for the pond novice.

With a new pond it can be difficult to manage water quality, you have just created a new eco-system that would normally take years to evolve so to just add all the new components and expect it to work from the off is expecting a bit much. With the entry of the fish you will be adding ammonia, nitrite, nitrates and changing the pH of the water. Therefore as with any new pond you need to keep a close check on the health of the fish for the first few weeks.

Ensure that your garden pond is safe

On a warm sunny afternoon, there’s nothing quite like sitting by the garden pond, sipping a cold refreshing drink and getting stuck into a good book.

In fact, garden ponds can provide pleasure all year round; with the fish, wildlife and plants that they attract.

But when maintaining a pond, there are the more practical elements to consider and safety should be a priority; particularly when there are children and pets in the house.

A basic but effective pond safety device is the safety net. This is the most widely used method to keep both pets and children protected from the dangers of an open pond. The net is placed above the water level and attached securely around the edge of the pond with specially designed fittings.

Most nets are designed to blend in with the pond so that its beauty can still be enjoyed. The nets can also be adapted to suit any size or shape.

Aside from a pond net, it can be a good idea to install adequate lighting around your pond. This means that you can continue to enjoy your beautiful garden even when the sun starts to set, secure in the knowledge that your children and pets are able to see the dangers easily.

Where can I put a garden pond?

Instead of going gung-ho and digging a pond in any location, a little time and thought needs to be given to the positioning of the pond and where any and how any services will travel to your pond.

You need to take into consideration any overhanging trees or any large shrubs that will provide shade to your future pond life. Whilst it is a good idea to have some shade so your fish can shelter from the midday sun, your pond does not want to be filled in the autumn with all the falling leaves and other garden detritus. Finding a balance is the thing to aim for, and whilst this may be difficult you will benefit from a little forethought in the future.

Another consideration is the positioning of the pond is in relation to services such as electricity and water. If you are installing pond pumps or pond filters you should carefully plan how the electricity supply will reach the pond, the longer the distance from the supply the longer the cable and hence the higher the cost. Remember, electricity and water does not mix, so consult a qualified electrician if you are unsure regarding anything concerning the installation.

A lesser consideration is of course the distance from the water source. Your pond will be self filling from rainfall, but water can be lost due to splashes from the pump or fountain, or from natural evaporation. If you need to fill your pond regularly it could take quite a few trips if the pond is some distance from the source.

The different types of pond liners

Posted in Pond Liners — Written by Steve

There are many ways you can construct a garden pond, but all of them have one thing in common, they all have to have some sort of liner to separate the pond from the underlying earth. These liners can come pre-formed to the exact shape of your pond or come as flexible sheets of waterproof fabric and are made from PVC, Butyl or the newer Epalyn.

If you use a preformed liner it can be difficult to match the shape of the pond to the hole you dig. You are going to be putting in a very large quantity of water so you don’t want any unsupported sections, this could cause the pre-formed liner to crack or split and all the water will soon disappear.

If you are using an Epalyn pond liner then you should use a suitable underlay beneath the liner. This will provide a protective layer under the liner so the liner will not be susceptible to punctures and will provide a support to the liner if the sub soil is loose. This underlay is available in rolls and is easy to fit to your pond space. When the liner is fitted over this underlay it will stand less chance of being punctured from above or below and should be maintenance free for years to come.

Pond pumps, filtration, fountains and waterfalls

Moving water in and around your pond is a good thing to do. It adds extra oxygen to the water that would only normally only be oxygenated by plants and surface oxygen absorption. And a fountain can add a great visual element to the water feature.

A pond pump can be used to power a waterfall, a fountain or as part of your pond’s filtration system to remove harmful substances and chemicals. Whilst a pump may not be required for small ponds, if you want any sort of water movement a pump is essential.

The pump is best installed whist you are planning your pond design, especially is you are planning on different levels of ponds so you can move the water between them. If you are planning on using a pond pump for a water feature and also filtration then you may want to consider two different pumps. This will mean you can switch the feature off at night to save electricity and still have the filtration system running.

Pond pumps come in many sizes and you will be amazed at just how much water they are able to move. If used for filtration the should be able to completely filter all the pond water in around 90 minutes, whereas if the are used for a fountain they should be able to provide a stream of water that is more than just a trickle.
Most online pond suppliers and manufacturers offer advice and can help you choose the right sized pond pump for your pond.
