I am an inexperienced gardener looking for some advice on whether to pare back the groundcover from around the base of trees and shrubs.

My garden was planted by landscapers around a year ago for my new house. Since then the ground cover (Myoporum parvifolium ) has taken off and is spreading everywhere including covering the base of the vines (ornamental grape vine), shrubs and trees (japanese maples). Should i be cutting a space in the groundcover around the base of other plants?

Regards

Alex
