I have some escallonia on the north side of the house and it gets a half-day's sun in the summer but in the winter, hardly any. A couple of them have suffered some damage from winter freezes and I pruned and reshaped them this spring in hopes they will fill in the bare spots.

They really haven't 'bounced' back like I thought they would and my question is: should I keep working with them or does their location warrant removal and replacing with something that is more shade tolerant?
