Not really - the plants you've had in it will have used up the nutrients in it Spread it around the garden, or add a layer in the compost bin.

You can use old compost if you have had no problems with diseases when you used it before. You could mix new compost in with it to add some nutrients to it or add other sources of nutrients to it

I regulary re-use compost, Spritz. I add fresh bonemeal as a fertiliser. If I have been re-potting Fritillaria bulbs that compost might go onto the garden and if a plant has been diseased or I have found vine weavil grubs in it, that would go in the rubbish bin. Otherwise it gets bagged up for re-use.

Really? I don't - it gets used around the garden and not thrown away, as I said. Each to their own, Mr MB.

I had a Fuschia in a large pot a couple of years ago,it died so I thought not an hardy variety as indicated at the gardencentre.But I was gobsmacked to find the compost was full of vine weevil so check your composts history and what was in it before reuse,
