I have 2 trees (I believe they're chamaecyparis lawsoniana blue surprise) planted in my front garden that have grown a bit too large for the space, visually. Could I top them down to a few feet tall, so they're more like a bush? I worry that would look pretty terrible, but would it also kill the tree? Or is it a viable option to continue pruning it to maintain a shorter shape? If it's viable, are there tutorials on how to prune it correctly? Thank you for your advice!
