    Trouble is, there's no perfect solution. Peat and coir are both pretty much clean but peat extraction destroys habitats and coir is shipped from halfway round the world. Green waste can contain undesirable stuff. I've had compost made from bark and wood chips/shreds and some batches were good whereas some were still pretty woody and not a good texture, and I can't tell until I open a bag which it's going to be. Maybe it needs more work (or just more time, and time is money) to get the composting process right. When it comes to green waste I suppose it's down to individuals to stick to the rules about what can go in, but there'll always be some who don't and councils/subcontractors can't check the contents of every bin. I would love for my own compost to be good enough to use for seed/potting but my garden is small so I don't have enough volume of garden waste for it to be hot enough to reliably kill weed seeds, and sieving to get the twiggy bits out is something I just don't have time for.
    I guess we all have to choose what we're prepared to compromise on.

    I know that some people don't like B Guinness, but here she discusses using municipal green waste in borders and raised beds. There is virtue in utilising resources closest to hand and not bringing in from a distance. That's one of the great thing about green waste compost - it should be available close to you for very little money.

    Our council used to bring free piles in the autumn for locals to take. I'm hoping they will start to do this again.

    What sort of quantity do you think you'll need?

    I have raised veg and soft fruit beds and filled them with topsoil and rotted manure.
    Both from CPA Horticulture
    I used about 80% topsoil and 20% rotted farmyard manure and mushroom compost.
    In hindsight I should have used less topsoil and more manure 60/40 as it needs more organic matter in there

    MPC is not formulated for long-term use really

  • Currently I only need about 250 litres or so; which is why I had opted for the smaller bags at garden centres. I might need more in future for other borders around the garden but as I am working through different areas of the garden it might take me quite a while and I wasn't sure how long soil can be stored for unusued.

    Whatever mix of topsoil/compost/manure you buy they'll be good for the season if you keep them somewhere sheltered from the sun and rain
