Replacing A Pond Liner.
Pond liners – Replacing a pond liner the best time to do this is early
spring or in the late autumn.
Often you can leave the old liner behind and place the new liner over
the top of it.
One good tip is to try and save some of the water by filling up a large
water butt to use in the pond once the liner has been replaced this will help restart the water balancing process.
