I'm a bit of a compost freak but haven't made any leaf mould yet and this
year decided I would. I know that you put them in a bag for about a year. Is
there anything else I need to do? Also, will any leaves with black spot or
other fungal or viral problems, be ok in with other leaves as it's so hard
to separate everything in the garden especially when the leaves are wet.If
everything breaks down properly, will these just be killed off or not?

My father used to collect up autumn leaves and fill a tea-chest with
them. He would then put a couple of inches of good soil on top of the
leaves as they warmed up and use the tea-chest as an over-winter
propagator for seeds or cuttings. Once the contents had done their job
they would be spread over his very productive allotment.
