Would I still seal the ends with endseal or similar? or would that inhibit fungus/spalting growth?Silver birch spalts very easily - but if you seal it in bags in the loft or anywhere else it wont happen. It needs to be piled up in the garden, so that at least some of the logs are in contact with the ground. Chuck some leaf mould over it to keep them moist, and to help introduce some "rot" to the party, a bit like a mulch, and forget it for a year. THEN seal it in bags. It gains the fungus that will start the spalting process by being in contact with rotting organics. They don't ALL need to be touching the ground, but as long as some are, and the other are piled on top, the fungus will transfer through the pile.
