I know out of a strem this would be a no no, but if I were to use the old silt from a pond would it be too detremental to just dump it on an empty bed that will later be built up?
The customer wants tom use the area for a rockery, and would prefer to not get a skip in to get rid of all the old silt. After wards I was going to add a load of good manure and fertilizer just so it has nutrietns and isnt just empty soil.
The pond has a small feed in from and out to a small stream, but its not moving much water through the pond to wash out the nutrients. The silt is about 2.5 ft deep (just under a metre) and hasnt been cleaned out for a few years. there are lilys in the pond, and a few leaves would have fallen in there over a few years.
Like I say, if it was form the bottom of a stream I wouldnt use it, but I would greatly appreciate any advice.
