my question is about my holly bush?
Why is my holly bush growing horizontal instead of vertical? It was growing vertical until a heavy snowfall a few years ago and now it is acting like a vine sending out long sideway branches! you can see by the picture the left side of the bush is now much lower than the right.
It does appear that the shrubs were weighted and began to grow in a horizontal manner.
The roots are always growing on evergreens and the weight of the snow shifted their position in the soil.
You can make some corrections with pruning, though I don't know if you can change the direction of the main branches with just pruning.
You may need to do a mini transplant to position the plants back into the soil.
