Pond maintenance in spring: give your pond some attention!

As spring arrives, temperatures rise. Most people head out into the garden, but the pond also needs attention. It's high time for pond maintenance! Problems during the growing season can be prevented by properly maintaining your pond in spring. As the water temperature rises, the fish become more active.

You can start feeding your fish once the water temperature reaches 8 to 10°C. Be careful not to overfeed, as if the fish don't eat all the food, it can actually promote algae growth.

Pond maintenance advice

During the autumn and winter months, many leaves and branches likely fell into the pond. This can cause the bottom to become highly acidic, leading to an unwanted algae bloom later in the spring. TIP: In March, you should remove all bottom debris. Restore the oxygen level in the water. This is essential to prevent algae growth. Ensure the pond water is hard, allowing oxygen-producing plants to thrive. Pond water softens due to precipitation in the autumn and winter. This means the pond water has few minerals. By adding foodstuffs for the pond the hardness of the water is stimulated.

Repotting aquatic plants or water lilies is important. Put some pond substrate in a plant bag, add the lilies, and they'll thrive again.

Don't forget to check your fish in the spring. Examine them carefully for signs of illness. If you see cottonwool-like spots, sores, or rocking movements, this could indicate parasites. Start feeding your fish carefully; as the water temperature rises, they become more active again and will need food.
