I am a very impatient sort. I put leaves into compost dalek for the winter and then come may I want the dalek. So what to I do with partly rotten leaves, so I simply bury them and planted beans on top. Had a good crop of beans and come autumn I dug through and the leaves had more or less disappeared and there were loads of worms. Also used the partly rotted leaves as a mulch, by the end of the summer they had disappeared too even though I had put straw on top to stop them drying out and blowing away. Having lots of leaves around seems to please the worms.
Leaves need fungus to decompose not sure that instant comes into it.
