A water feature or pond can transform a garden, we’ve created a few ourselves. For example this modern garden, including a small rectangular pond with a little waterfall.
Just like every other part of a garden, a pond must be maintained well to retain its beauty. The recent warm weather we’ve had in the UK will have warmed up your pond water, making it the perfect environment for algae and other weeds to grow – making your pond go green, rather than staying clear. This is the perfect time to sort it out, and we have this list of things you can do to clean up your pond and hopefully keep it that way.
If you have a variety of fish in your pond then it is likely you will need a filter. On the other hand you may choose to only have a few or no fish and so go without a filter.
Many believe that a filtration system works by removing dirt from the pond, this however is not the case. Filters instead remove harmful bacteria from the pond, breaking it down into chemicals which are beneficial to plants and fish.
There are two different types of filters available, one for ponds with high amounts of fish, and another for ponds with low amounts of fish but high amounts of plants. Filters can be purchased in different sizes depending on the volume of your pond.
Ultra Violet lights can also be used along side an existing pond filtration system, these blast the harmful algae with high level of UV light which causes them to bind together – this means they can be broken down more easily.
String weed is a type of pond weed which cannot be prevented through filtration. There are other ways to deal with it though. A cheap fix is to use Barley straw, which can be stuffed into a container (like an onion bag or a hay net). This can then be placed in the water. After about eight weeks the string weed should be no more. The hay must then be removed from the pond and replaced.
Alternatively for more immediate results, a chemical can be used (String Algae Control) which will clean up the weeds much faster.
A much more simple method (albeit more time consuming) is to use a stick. Simply twist the string weeds around the stick and they can easily be plucked out.
Filters must be changed and pipes must be maintained and checked for leaks in order for your pond to operate smoothly, plants may take some time to place, but once they’ve settled in they shouldn’t require a lot of work. An easy thing you can do to prevent weeds is to plant water lilies. These plants can produce a beautiful flower which can really make your pond stand out. Water lilies also provide a lot of shade, this makes it harder for unwanted greenery to grow underneath.
