Composting pond weed
In autumn and early winter garden ponds should be cleared of excess
weed and dead leaves. Marginal plants that have died down should be
cut back and removed. All this dead vegetation must be taken out of
the water. If it is left to decompose in the pond the bacteria that
break it down take oxygen from the water and may not leave enough
for fish and other animals to survive.
ADD THE DEAD VEGETATION FROM THE POND
TO YOUR COMPOST HEAP
It will rot down quickly and enrich your compost.
The worms in your compost heap will love it.
In the autumn a lot of dry, stalky material goes in to a garden
compost bin. This needs balancing with wetter, more nitrogen rich
vegetation but there are no longer grass mowings to add. All the wet
pond weed will moisten the contents of your compost bin and make it
a more suitable place for the worms to work - you will find them
lying amongst the fronds of pond weed.
Another good reason to compost all material from a garden ponds is
that some species of pond weeds have proved very invasive and have
spread uncontrollably through rivers and canals, choking them.
If you do not know whether the weed in your pond might be a problem
it is safer to compost it. NEVER THROW POND WEED OR PLANTS IN
TO A RIVER OR LAKE.
