A spruce tree or plant is usually thin and not very big, often growing in cold places. It's also an adjective used to describe something that's neat, well-organized, or tidy.
You might have seen pictures of a Christmas tree made from one type of evergreen tree called the spruce. But even without a festive context, you can use the word "spruce" in everyday conversations. For example, someone might say their house was a bit cluttered and they decided to spruce it up with some cleaning or new decorations. The idea is that something becomes more attractive or enjoyable after being made neater or improved.
