Sweet Revenge! Posted June 30, 2017 Report Share Posted June 30, 2017 I have changed from using sand/grit to perlite this year and I just wondered what other folk do with their spent compost when it has perlite in it? My old compost from re-potting used to go straight on the compost heap and thence on to the garden. Apart from perlite looking pretty unnatural, I wonder how long it takes to break down? Will it end up in the sea like nurdles? I have a river at the bottom of the garden and a sea loch only a few hundred yards further on. I realise in the great scale of life I'm not talking about tons of the stuff, the only thing I could think of was to put it in a bucket with water, give it a stir and see how much I could float off the top. There is nothing like a bit of OCD to exercise the mind ;) Quote Link to comment Share on other sites More sharing options...
Dunc Posted July 1, 2017 Report Share Posted July 1, 2017 (edited) Onto the compost heap! Never really noticed it once its been 12 months there and then onto the garden. Edited July 1, 2017 by Dunc Quote Link to comment Share on other sites More sharing options...
ian Posted July 1, 2017 Report Share Posted July 1, 2017 Why bin it? mix it with some fresh compost and use it again. You save money, it won't get into the water course, it's win/win. Quote Link to comment Share on other sites More sharing options...
Sweet Revenge! Posted July 1, 2017 Author Report Share Posted July 1, 2017 Thanks Dunc and Ian. I wondered if it would just go dark and not show up. I do like the idea of recycling it though and I suppose it could be sterilized before re use to get rid of any potential nasties. Quote Link to comment Share on other sites More sharing options...

Loakesy Posted July 3, 2017 Report Share Posted July 3, 2017 If my old soil is clean (ie, not overcome with weeds or pests) it goes straight back into the bin with the rest of my soil, mixed in and re-used. Why waste it? Anything that us unusable goes on to the compost heap 1 Quote Link to comment Share on other sites More sharing options...
