Leaf mould?

Second question of the day :)  Leaf mould: I have tons of leaves and a compost dalek.  Would you put the leaves in the dalek with all the other stuff or "make leaf mould" by sticking them in bags?  What's the difference with / use of the end product and does keeping them separate speed up / slow down the process?  Leavs are silver birch and apple.

Thanks!

    Coincidently your answer is here

    Compost uses bacteria and leaf mould uses fungi apparently,

  • Leaf mould, is a cool fungal process and can take 1-2 years, depending  on whether you shred them first. 
    Proper composting should be a hot relatively fast process largely driven by bacterial action.  The conventional advice is if you only have a few leaves then best mix them into the general compost. If you have plenty of leaves make a leaf bay  and treat them separately.  The alternative option is to  put them in old compost bags . A bag full of leaves will only give enough leaf mould to mulch round 2-3 plants . At all times keep leaves damp, dry leaves will not break down.

  • Thanks @Allotment Boy  - yes, I've read the article referred to by @Kili which refers to the relative slowness of decomp.  Sounds like the mould is worth keeping separate for eg seed compost (fine, not too rich)?

    It takes a very long time for leaf mould to be fine enough for seed or similar, and you'll need to sieve it, even if it looks pretty good. Most people tend to use it as a soil improver or mulch, and it doeesn't have to be too fine for that. 
    I'd echo the others when saying that it's better to have them separate, as it's a different process for breaking down. You can certainly speed up the leaves by shredding [a mower is fine] but it depends how much you have and whether that's feasible. 
    Compost bags are ideal if you don't have room for a leaf cage, and you can turn them inside out so that they look better. They need plenty of holes in them, and the leaves also need to be kept damp. If you make a cage, just check them now and again to make sure they have enough moisture. That will depend on your climate, and where you have the cage sited. Many places have very dry winters, so if that's the case, you can give them a bit of water, and a quick mix so that it's evenly distributed.  :)

  • Thanks @Fairygirl !
  • Mine and Killi's post crossed but at least we said the same thing. 😀
    Another use for leaf mould I heard relatively recently is for hardy perennial and shrubby cuttings. Apparently it encourages very strong root development.  Not tried it myself yet, but I will.
