Question

What is the best fall arborvitae fertilizer?

Answer 1

Usually I wouldn't recommend fertilizing mature trees, as they will get plenty of nutrients from the ground. If you still choose to fertilize, then you will want to use a general purpose fertilizer that is slow release so that you do not over-dose them with nitrogen too fast.
