Used Compost?

Whats the best thing to do with used compost from pots and seed trays?

    Compost it, throw it onto the garden, re-use it to fill the bottom of large containers/pots and top the rest with fresh, bottom of hanging baskets.

    Just a few ideas - I'm sure there's more.

    I throw it onto my clay soil, a bed a month slowly it's helping improve soil

    I put it on the veg bed, and some around the plants on the flower bed - mixed with organic chicken manure pellets.

    Me too Linda, hate to waste it and you're right it does slowly help improve it.

    For potted annuals, use it half / half with new compost, we have done that for years, with the addition of some pelleted fertiliser.  Otherwise as the others say, put it on beds, add to your own compost etc.

    Zap it in the microwave for about 5 minutes to sterilise it, keep covered and use as seed compost.

  • Oh, Fig thats a great idea? Although OH may complain as already have seed trays on all windowsills and one in the fridge image it helps with clay soils? I have a section in the garden thats really bad and was wondering what I could do to help it break up a bit. Like Mandy has you leave it on top or dig it in?

    I mix it up with new compost to use in pots etc. Might consider throwing it on the beds though now. Is it best to dig it if you want to improve the soil or does it just become incorporated over time?

    Just use it as a mulch and the worms will incorporate it into the soil for you.image

    A trowel in the hand is worth a thousand lost under a bush.

    @Sam Glendinning - it does get a bit whiffy, I've got an old microwave in the shed that I use.
