6 essential autumn pondcare jobs
Remove dead leaves and debris using a net. This material will sink to the bottom of the pond, creating sludge. Cut back any overgrown plants that may drop into the water.
Clear out weeds such as blanket weed from the surface, using a bamboo cane. Leave debris on the side of the pond for a few days to allow any pond creatures to return to the water.
Use a fine mesh net or plastic scoop to clear out silt or sludge from the bottom – there’s no need to remove it all as a layer of silt will provide protection for pond creatures.
Cut back upright marginal plants to around 6in/15cm above the water; likewise any submerged oxygenating plants that have outgrown their space and risk taking over.
Remove overhanging tree branches and any foliage that has spread across the surface, such as old water lily leaves. This lets in more light, which oxygenating plants need to grow.
Reassess your pond plants: take out some if you have too many (overgrown plants can be divided in the spring); lift any tender or half-hardy plants that need winter protection.
