Gravel under a tree?
This must be a common problem.
I have a lovely Acer tree in my very small front garden. It has reached 10ft tall by 6ft wide, and I suspect this is close to the maximum size. It is so dense that it throws heavy shade on the lawn, which as a result has become a mixture of moss and straggly weeds.
I'm thinking of replacing the grass with decorative gravel around the tree, spreading in a circle from the trunk to the perimeter of the tree. Is this a good idea, and how far do the tree's roots spread?
Many thanks, Andrew.
