Maintenance of your pond in autumn

Pond maintenance in autumn

The basis for a beautiful pond in summer begins in autumn. A pond does not need as much maintenance during the winter months but well begun is half won!

Cleaning the pond

Dead plants and blown-off leaves are removed from the pond to avoid them rotting on the bottom.

Organic remains on the bottom increase the risk of algae and are harmful to overwintering fish.

You can do this job very well with a landing net.

One of the landing nets you can find at Zizzoo:

Superfish scooping net 38x35x220cm fine

You can also use a scoop net for rotting leaves or silt on the bottom. A dedicated pond hoover is of course the most useful to keep the fine silt from swirling all over the pond.

Some pond vacuums that you can find at Zizzoo:

Pontec Pondomatic

Pondovac 4

You can also dissolve soil sludge with:

Bio booster 6000


Maintenance of pond plants

For aquatic plants whose foliage dies off in autumn, you can remove these dead plant parts. If necessary, you can repot and/or divide plants that have grown too large; this will make them grow stronger in spring.

Good plant stock ensures that so many nutrients are absorbed from the water that there will be much less algae.

Water values

To prevent pond water acidification, the gH value should be at least 8 before winter sets in.

However, a water hardness of at least 10 is recommended to allow oxygen plants to develop in time during the year. If the value is too low, oxygen plants will not grow well and algae problems will occur.

You can increase the gH value with:

gH strong acting 2L

gH strong acting 3L

The right kH value (carbonate content) is going to buffer excess CO2 without affecting the balance of the pond. A kH value of at least 6 is recommended.

You can improve this value with:

kH strong acting 2L

kH strong acting 3L

Pond technology

Pond owners sometimes make the mistake of shutting down pond filters in winter. There are important bacteria in the filter material that are killed by shutting down the filter. These bacteria help break down dirt and prevent excessive algae growth.

We therefore recommend keeping filters in operation during the winter period but then also protecting them from freezing temperatures.

Ideally, the pond pump should be placed so deep in the water that it cannot freeze or placed on dry land in a frost-free area.

For waterfalls, skimmers and the like, however, it is better to put these pumps out of action during the winter period. It is also best to remove nozzles, pipes and hoses to prevent frost damage.
