How to maintain slender sky pencil holly
Last year we had a significant amount of heavy snow that weighed down on the branches of our sky pencil holly, causing the branches to splay out horizontally. The holly survived just fine, but the branches did not return to their typical vertical shape. It's very "bushy" looking now. Can I wrap the branches to retrain them to grow upwards? What is recommended?
You can certainly tie them together in areas of heavy snow. In fact, it's rather a common practice.
