Spent compost

[ChocoHazelnutCroissant]

I have some compost in the back garden that, well, doesn’t work, if you will.
I’ve tried to grow things in it to no avail, and the compost is just sat there in containers, looking a bit unsightly.
We are planning to tidy up the garden in the next few days, so where can we dispose of it responsibly?

I assume you mean commercially bought bagged compost, in which case it contains feed which will only nourish the plants for a month or two. After that it makes an excellent soil conditioner so sprinkle it on your flower beds.

Alternatively, if it’s not had diseased plants in it, tip it out, fluff it up and add generous quantity of slow release fertiliser granules and it will go again.

I add mine to the compost bin or just sprinkle over the flower beds. I only tend to empty out completely if it is infestested with vine weaval. Then I spreed it out over a plastic sheet on the lawn for the birds to pick over before spreading.
Most pots I just replace the top half of compost with John in es number 3 and add slow release pellets when planting.

Agree with others, it is good as a soil conditioner on the flower beds. Tip the pots out, get rid of weeds, clumps of roots and any obvious pests (including any little creamy-yellow balls (they are eggs of vine weevils & other pests) and spread the compost over the beds.
