I collected all of mine in a big bin liner. Then I get a pair of old garden shears and absolutly pulverize them into little pieces.

That reduces 3 bags into only 1 bag full.

Then hose them down with water, get a kitchen glove and mix it all in proper making sure every leaf is wet. Add some grass clippings and then stack the bags on top of each other.

They will be ready in less than a year. I checked recently, the fungus has set to work, ants, woodlices etc. Most of them are brown some are black.
