I have had a dead tree (killed by ivy) in the corner of my (French) garden for years and, the other week I decided to cut it down for firewood. It turned out to be partially hollow... in the process of hollowing, as one might say. I think it was a hazel tree, but I am not sure as it has been dead for as long as I remember and obscured by ivy.
As the logs are drying out I have a few litres of the dust-like residue of the tree 'innards'.
Does anyone know if this ('raw') makes good, bad or indifferent compost. I love germinating 'difficult' seeds, and it occurs to me that it might be rich in gibberillins to aid germination...
