I have a monkey puzzle tree planted 3 years ago at around 8 inches, which is now around 14 inches, the tree is around 4 metres from a mature silver birch and a similar distance from a mature pine both of which are around 10 metres tall, the roots of the silver birch appear to be protruding through the surface as a result of an unusaully wet winter and are now within 1 meter of the monkey puzzle tree. Whilst the monkey puzzle still seems to be growing, albeit very slowly, should I replant or take action to remove some of the roots from the mature trees nearby? any advice appreciated.
They'll all be on a collision course in the long term - a mature Monkey Puzzle has branches 5-6m or more long, and not much less for the birch and pine. Their root spreads will be even larger too, but are less likely to be a problem.
