I have a large umbrella green acer which has been in a large pot for around ten years. It is around 3.5 feet in diameter and up until this year has been glorious.
I have now discovered the plant is totally waterlogged. In an attempt to drain this off, my other half has broken a root from a cm hole in the bottom of the pot which was leading to an inch thick root in the ground. At the moment the pot is tipped slightly and there are thinner roots (unless also damaged) rooted from the pot into the ground.
Can I save this and if so what is the best thing to do now?
