Would planting a shurb of weigela 4 feet out from my grandaflora interfer with the roots of the tree?

Question

I want to plant a drift of "My Monet" weigela about 4 feet out around my Bracken's brown beauty tree. Would this interfer with the growing of the tree or root competion? Thanks

Answer 1

General rule of thumb is that the roots of an established tree extend as far as the spread of the branches.Based on this,one can deduce if a new planting might succeed.
