Notes:
I have had this Acer for over a decade and on moving house last year had to top it off. Fortunately this was an early Spring move so the tree was still inert. Lusty Spring growth followed but had bad infestation of Aphids – treated successfully with garlic spray. Over winter, the pot became waterlogged. In March I removed the tree from its pot, cut back some root and and refilled with John Innes #2. Also raised up above the gravel on a pot mover.
