All true, but horse chestnut is also prone to rotting from the inside out. I managed to salvage about 500kg from a tree in Edgbaston, but the rot was everywhere and it spreads in a very radial form, thereby creating a lot of waste. OTOH, the colours in a spalting horse chestnut are quite unbelievable. Didn't get much burr or rippling, so well done, Paul.
