Absolute newcomer to ponds and soon to be the proud owner of a large (and historic) clay-lined, natural pond... partially excited, partially filled with fear and trepidation. Can I have broad (preferably experienced) views of whether this pond should have a pump fitted, best plants to reinstate, and whether to try and dredge some of the silt out? Pond is substantial with open entry and exit routes for the water but generally sits still in the summer months. Could be beautiful but has been somewhat neglected... all advice gratefully received.
