Trimming Holly ‘Tree’
I have a Holly tree and it is about 10 feet tall. It is not looking as healthy as it has in the past year. Can I trim the tree to a short height? Also, the leaves are turning a yellow tint and is not as green as it use to be. I put Miracle Grow tree spikes (2) in the drip line of the tree, hoping it would assist the tree in becoming healthier. Can I prune the tree back, and what can I do to get the green foliage back to where it was? Also, how far do I cut the tree back and what can't I do when pruning?

You can trim the plant back by at least a third and it should be fine. Any further than that can cause problems.
